Choosing a Spray Gun – A Complete Guide

Posted on by

The intent of this article is to cover all the important things to consider and provide information to help you choose the right spray gun for you.

 

If you are just getting started in spray application you may be over whelmed by all the variables that are to be considered. From choosing the right coating, to safety considerations when spraying, to choosing the actual spray equipment. If you have been able to wade through the choices you may be at the point that you have decided you will be using a spray gun and want to determine which spray gun will best meet your needs.

 

Variable 1 – Fluid Viscosity

 

Viscosity is usually referenced as low, medium or high but if you do not have the viscosity of your coating provided you can also use a measuring device like a Zahn cup which will give you a reading in seconds. You can then use a conversion chart to determine the viscosity of a given coating. Most spray gun manufacturers including Binks and Devilbiss will often list the proper spray gun set up based on the coating viscosity you will spray using a certain cup like for the Trophy Gun the viscosity is listed in seconds in a Zahn 2 Cup. You can also often get a spray gun recommendation on the technical data sheet for your coating. However if you will be spraying a variety of coatings then having a general reference point of the coating type and viscosity of the coating will give you the ability to reference what spray gun setup might be ideal.  In general certain types of spray guns are better suited for heavy viscosity coatings than others.

 

For high viscosity coatings like zincs, enamels, ceramics, or glues you will typically want to use a conventional spray gun. Or if you need to spray even heavier bodied coatings or need higher production then you will often want to consider an Airless or Air Assist Airless.

 

For other coatings it will depend on your finish requirements. HVLP will help reduce the coating you use by having higher transfer efficiency. LVMP will allow for similar transfer efficiency to HVLP but may not meet environmental regulations in certain industries, conventional will provide the finest atomization but can use twice as much paint in a given time that HVLP will.

 

In addition to having implications for the type of gun to choose, viscosity will also be important in determining how fluid is delivered in a spray gun. The three ways to feed paint to a spray gun include pressure, suction, or gravity. Each feed method has its benefits and limitations. In general Gravity feed spray guns will keep waste to a minimum and provide ease of use. However to use a gravity feed spray gun the material must be thin enough to flow easily. Suction feed spray guns will have similar fluid flow requirements to gravity fed spray guns. Suction fed spray guns do offer potential agitators which can be helpful for coatings that require agitation. Suction feed spray guns will require slightly more cleaning. If your coating is highly viscous you will most often need a pressure fed spray gun. Pressure feed spray guns can supply highly viscous coatings easily making them the ideal choice for high viscosity coatings.

 

Variable 2 – Production Requirements

In addition to a variety of feed methods and air cap styles, high quality spray guns have a variety of set ups available. By offering larger air caps and fluid nozzles you will be able to choose a spray gun that will be able to provide the production level you need or if a spray gun is not fast enough you may want to consider an airless.  You can get an idea of what production you can expect out of various fluid nozzles here. The Air Cap you choose will determine a few important things including the size of the spray pattern and the caps ability to break up heavy viscosity coatings the higher the CFM of the air cap typically the heavier bodied coating it will atomize. BY knowing your production requirement you can be better able to choose the right fluid nozzle and air cap

 

In addition to choosing the air cap and fluid nozzle the Production requirement will be pertinent in choosing how you feed your spray gun. Pressure pots offer higher volumes of coating which can be ideal if you will be spraying more than a gallon of paint at a time. They also provide greater control over your fluid and air pressures which can help in meeting a production goal. Or if you need the ability to continuously paint you can feed your spray gun from a diaphragm pump or fluid transfer pump. If you will be painting in small quantities and not have coatings with high viscosity then gravity or siphon feed spray gun could be ideal.

 

Variable 3 – Compressed Air Availability

Different spray equipment will need different amounts of air. A typical spray gun can require 20 CFM of air while an airless can often require significantly more if it is air fed using up to 120 CFM. You can learn more about compressor requirements for spray equipment here.

 

Variable 4 – Finish Quality Requirements

A final variable to consider is the finish requirements you will need. Spray guns are typically the best appearing finishes. If the coatings are not highly viscous most of the times you can achieve an automotive quality break up of a coating with HVLP, Conventional, or LVMP.

 

However with heavier bodied coatings you will typically need a conventional gun to get good break up. An air assist airless will provide a finish that is close to a spray gun but not quite the fine finish, they are often used for higher production that requires a quality finish. If you primary need high production or spraying high solids coatings you will typically need an airless.

 

Variable 5 – Length and Diversity of Use

Spray guns vary greatly in their prices as well as their quality. Higher quality spray guns offer greater variety of air caps, fluid nozzles, and are able to be completely rebuilt. Lower cost spray guns will often not be rebuild able and have limitations on the variety of set ups that are available. You can learn more about spray gun prices and quality differences here.

 

Conclusion

Choosing the right spray gun for your coating can be a lot to consider. By knowing more about your finish quality, production, compressed air, and viscosity of your paint you will be able to better determine the right spray equipment for you.

How to Use a PEX Crimping Tool

Posted on by

In this article, I’m going to show you the usage of a PEX crimping tool and where to find it.

 

It is best to rent a PEX crimping tool when installing PEX pipe. This tool is a necessity to perform your task, but it is only used for this reason. This is why it is better to rent than spend your money on a new one that will only more than likely be used this one and only time.

 

A PEX crimping tool is a tool that is used when you are installing PEX pipe. It is used to create a water tight seal when finishing off your piping project by securing the crimp ring into place on your pipe.
PEX Crimping Tool

How It Works

Installing PEX pipe is not a complicated procedure, but it does take special works and tools to get it done. Obviously the crimp tool is one of those tools that are necessary.

 

When you have cut your pipe to the size you need it, you will want to slip on crimp rings over the ends of the just cut pipe. Then you will take a fitting, and push it into the tubing. Slide the crimp ring to the edge. Now you are ready to use your PEX crimping tool.

 

Take out your rented tool and open it. This is done by pulling the handles apart to create an opening. Put the opening of the tool over the crimp ring on one end of the PEX pipe. Make sure it is on well, and then shut the tool by pushing the handles back together. This creates an extreme amount of pressure and forces the crimp ring into place. This then creates a water tight seal, which is obviously something any home owner is seeking when dealing with piping projects.

 

 

Only a PEX Crimping Tool

Some home owners have tried to seek out another possible way that the above procedure could be done. One that doesn’t need a PEX crimping tool. Unfortunately in order to replace your old piping with PEX pipe, or even if you are doing new construction, and are starting off with PEX pipe. The only proper, secure, and safe way to get it done is if you have, or have access to a PEX crimp tool.

 

This is the only tool that creates enough force and pressure at just the right areas to be able to securely smash the crimp ring into where it is supposed to be. Using another tool, or finishing this procedure in any other way can result in a faulty crimp ring, or fitting, causing the pipe to leak, which in turn causes damage to the home.

 

All home owners know that a leaky pipe is not what they want to wake up to Saturday morning. So, save yourself the trouble and rent a PEX crimping tool. This will ensure that the job is done right the first time, and there will be no long term problems with leaky pipes, and no danger of finishing the project missing some essentials.

Learn About Composite Materials

Posted on by

Does “composite materials” sound familiar? And do you know what it is? This overview will show you a brief discussion of composite materials.

 

Definition

A “composite” is when two or more different materials are combined together to create a superior and unique material. This is an extremely broad definition that holds true for all composites, however, more recently the term “composite” describes reinforced plastics.

 

Background on Composites

The history of composite materials dates back to ancient times for construction applications; straw was mixed with mud to form a building material known as adobe.

 

The straw provided the structure and strength, while the mud acted as a binder, holding the straw together in place.

 

Since the days of adobe, the use of composite materials has evolved to commonly incorporate a structural fiber and a plastic, this is known as Fiber Reinforced Plastics or FRP for short. Like straw, the fiber provides the structure and strength to the composite, while a plastic polymer holds the fiber together. Common types of fibers used in FRP composites include:

 

  • Fiberglass
  • Carbon Fiber
  • Aramid Fiber
  • Boron Fiber
  • Basalt Fiber
  • Natural Fiber (Wood, Flax, Hemp, etc.)

 

In the case of fiberglass, hundreds of thousands of tiny glass fibers are compiled together and held rigidly in place by a plastic polymer resin. Common plastic resins used in composites include:

 

  • Epoxy
  • Vinyl Ester
  • Polyester
  • Polyurethane
  • Polypropylene

 

Examples of Composites

The most common example of a “composite” in a broad sense is concrete.

 

In this use, structural steel rebar provides the strength and stiffness to the concrete, while the cured cement holds the rebar stationary. Rebar alone would flex too much and cement alone would crack easily. However, when combined to form a composite, an extremely rigid material is created.

 

The composite material most commonly associated with the term “composite” is Fiber Reinforced Plastics.

 

This type of composite is used extensively throughout our daily lives. Common everyday uses of fiber reinforced plastic composites include:

 

  • Aircraft
  • Boats And Marine
  • Sporting Equipment (Golf Shafts, Tennis Rackets, Surfboards, Hockey Sticks, Etc.)
  • Automotive Components
  • Wind Turbine Blades
  • Body Armor
  • Building Materials
  • Water Pipes
  • Bridges
  • Tool Handles
  • Ladder Rails

 

Benefits of Composites

In comparison to common materials used today such as metal and wood, composites can provide a distinct advantage. The primary driver and advantage in the adoption of composite materials are the lightweight properties. In transportation, less weight equates to more fuel savings and improved acceleration. In sporting equipment, lightweight composites allow for longer drives in golf, faster swings in tennis, and straighter shots in archery. While in wind energy, the less a blade weighs the more power the turbine can produce. Besides weight savings, the most important benefits of composites include:

 

  • Non-Corrosive
  • Non-Conductive
  • Flexible, Will Not Dent
  • Low Maintenance
  • Long Life
  • Design Flexibility

 

If you have any interest in composite materials, you can try to visit the website of Taiwan Electric Insulator Co. Ltd. TEI has a vast range of specific material for your needs, from electroplated glass-fiber, the latest bulletproof aramid fabrics to high spec carbon fiber and carbon modulus.

How to Choose the Best Anti Glare Screen Protector

Posted on by

When it comes to the transmission of visible light, both glass and sapphire are exceptionally transparent, but the reflectiveness remains one of the biggest problems. Manufacturers use various techniques to scatter reflected light in order to reduce glare, with varying results. The most commonly used technique for displays is called Anti-Reflective coating, or AR coating. It’s based on a thin-film interference principle which is also why soap bubbles produce colorful striations under the sunlight.

 

AR coatings have been around for a while, mostly used for luxury watches and prescription glasses. With more advanced, multi-layer compositions, it most recently made it into handheld devices — Apple Air 2 came pre-equipped with its own AR coating with no visible decrease in contrast and color intensity. It’s by far not a perfect solution, especially when it comes to smartphones. AR coatings come off easily, resulting in a large number of tiny “opaque” scratches and spots which interfere with a user experience. Phone screens are also more prone to scratches and wear than watches or tablets.

 

Screen protectors can help deal with glare issues. There are currently two options: matte finish and AR coating. Both solutions come with some drawbacks which you need to be aware of during your purchasing process. This quick overview will help you choose the Best Anti Glare Protective Film for your specific situation.

 

Anti-Reflective Coating for Tempered Glass Screen Protectors

 

AR coatings are used for tempered glass screen protectors (though not all tempered glass screen protectors come with AR coating). It is hardly noticeable, and colors and contrast look almost the same. As mentioned above, over time, the coating will rub off, or scratch off, and will significantly reduce the anti-reflectiveness. Devices with an AR coating need to be treated with extra care. In case of AR coated tempered glass screen protector, be prepared to get a replacement soon.

 

Matte Finish for Film Screen Protectors

 

The other option is to create a textured surface on the screen (often called a matte finish), which reduces glare and scatters reflections. You may recall that early Apple displays were matte, but to the disappointment of many, no longer are. A matte finish hides fingerprints and smudges better, and since it’s not a coating, it cannot be scratched or rubbed off. This finish, however, has its own drawbacks. Because the texture makes the light waves hit the surface from different angles, you might notice tiny color speckles. Some people love the matte finish, while others don’t — it’s a matter of personal preference.

 

Prochase Enterprise Co., Ltd. is the leading protective films manufacturer in Taiwan. They provide kinds of high quality protective films such as anti glare films, anti fog film, anti scratch film etc. products for clients. If you are looking for the best protective films to protect your screens, please don’t miss the website of PROCHASE, the most excellent products and services won’t let you down.

How to Choose the Right Oil and Grease for Your Equipment

Posted on by

With the Environmental Protection Agency (EPA) emissions regulations, the use of higher-grade engine oil is mandatory to maintain proper engine performance. A benefit of the newer oils is that they’re compatible for use in earlier engines.

 

There are two characteristics to look for when choosing the right engine oil for your compact equipment: classification and viscosity rating.

 

Oil Classifications

Oil categories for use in diesel engines begin with “C.” The American Petroleum Institute (API) CJ-4 category was introduced in 2006 and was intended for high-speed, four-stroke diesel engines. It was designed to meet 2007 model year on-highway exhaust emission standards, and is uniquely formulated to avoid impacting new diesel engine technology durability.

 

In December 2016, API introduced a new heavy-duty oil engine category: CK-4. The new formulations help protect engines from high-heat, high-load conditions typical in non-road applications. CK-4 oils are backwards compatible with all trucks and non-road equipment that use CJ-4 oils.

 

Always use premium oil that meets or exceeds the API service classification of CK-4 for EPA-compliant engines.

 

Viscosity Matching

It’s important to properly match the viscosity rating of your engine oil to the outside temperatures at your work environment. Always refer to the Operation & Maintenance Manual to determine the weight of oil that is recommended in various conditions.

 

A 10W-30 weight oil is a common factory-fill for many current production machines. It offers top performance in temperatures typically ranging from zero degrees F to 90 degrees F and above. A 15W-40 weight performs well from 25 degrees F to 110 degrees F and above.

 

Synthetic or synthetic-blended oils are formulated with additives that can extend oil change intervals and promote longer engine life. A 5W-40 weight synthetic oil is usually capable of providing protection in harsh conditions as cold as minus 40 degrees F and as hot as 120 degrees F.

 

Hydraulic and Hydrostatic Oils

Hydraulic and hydrostatic oils are formulated to meet the growing demands placed on hydraulic components, and there are several different types of these fluids for various applications:

 

  • High-performance — Typically, a custom blend of high-quality lubricants designed to provide peak flow at subzero temperatures while maintaining stability during periods of high-temperature use.
  • Synthetic — An advanced liquid technology designed to optimize cycle times and productivity, and provide good cold weather fluidity for seasonal changes.
  • Biodegradable — Introduced to meet customer demand as federal, state and local governments set environmental-related project restrictions. It’s biodegradable, non-toxic and formulated to reduce the potential for environmental damage.

 

Grease

Many machines require grease as a lubricant in pivot points where pins and bushings are located. The lubrication points need greased at various intervals specified by the machine manufacturer. If used correctly, the right type of grease will help extend the life of components:

 

  • Multi-purpose #2 — Developed for normal applications, it provides lubrication to prevent rust and corrosion and protection under heavy and shock loads.
  • Heavy-duty — Containing moly for better adherence to all surfaces, it offers water resistance, extreme pressure capabilities, pump ability in cold temperatures and good seal compatibility.
  • High-performance — Formulated to provide high-temperature performance in severe operating conditions, it’s intended for lube points with sliding and pivoting movements.

 

In view of above, if you want to choose the right engine oil and grease, I recommend that you can visit the website of Min Jung Hong. They are the professional manufacturer of specializing in high performance motor oil, heavy duty machinery oil, agricultural lubricants, MoS2 grease, fuel injector cleaner and more. Learn more information about lubricant and oil, try to check out Min Jung Hong’s product pages and feel free to send inquiries to them.

How to Make Beaded Safety Pin Jewelry

Posted on by

Why Safety Pins Are A Fashion Staple

 

Safety pin jewelry doesn’t sound super sophisticated, but even the high fashion world has embraced the trend. For years, safety pins have cycled in and out of style, which makes them an accessory staple. Fortunately, you don’t have to spend hundreds of dollars on a couture version of the look, nor do you have to go bare bones with safety pins like the punk rockers that sported them in the 1970s and ’80s did.

 

For just a few bucks, you can make your own beaded safety pin jewelry, be it a pair of earrings, a necklace or a bracelet.

 

It’s a fun and easy craft to make and even more fun to wear. With these instructions, you’ll transform an ordinary safety pin into a fashion statement. It’s as simple as slipping some seed beads onto the pins. They make great gifts for tweens and teens or for the adult who’s perpetually young at heart.

 

The Supply List

The supply list for safety pin jewelry is pretty simple. In addition to the pins and the beads, it is helpful to have needle-nose pliers and a small flat-head screwdriver. You can find all of these items at a chain craft store like Michael’s. Art supply stores also carry these goods.

 

How Many Safety Pins Do You Need?

How many safety pins you’ll need depends not only on the pattern you choose but also on the kind of jewelry you want to make. The typical safety pin jewelry project will require between 10 and 14 small pins.

 

From there, you can open the pin, and slip the seed beads onto it. Once all beads are in place, close the safety pin. You may want to use the needle-nose pliers to pinch the end of the safety pin so it will not pop open later. Repeat this step until all the safety pins are beaded.

 

Connecting the Small Pins to One Big Pin

Now you are ready to put all the beaded pins onto a larger safety pin.

 

 

Open the large safety pin (the size you need that will be stated in the pattern you choose). Use the flat-head screwdriver to slightly pry apart the coils at the end of the large pin.

 

Slip the loop of the first beaded safety pin onto the large one. Pull it down to the loop at the base of the large pin. Pull it around the loop and up through the backside of the pin. Repeat this for each beaded safety pin.

 

Once all your beaded safety pins are on your larger pin, use the pliers and squeeze the loop to close it. You can now affix your new safety pin jewelry to your shirt, hat, shoelaces, etc.

 

Shuen Fuh Enterprise Co., Ltd. provides kinds of safety pins for customers. Their factory is equipped with the state-of-the-art equipment to develop and manufacture high quality safety pin products in assorted sizes, styles, and shapes for your applications. If you are interested in learning more information about safety pins, welcome to visit Shuen Fuh’s website to browse more relative products.

The Ultimate Guide to Plastic Recycling

Posted on by

Plastic is among the most popular and important materials used in the modern world. However, its popularity is part of the huge problem and reason why plastics should be recycled. Instead of throwing them away polluting the land and our water bodies, we can optimize the lifespan of plastics by recycling and reusing them.

 

Plastic recycling refers to the process of recovering waste or scrap plastic and reprocessing it into useful product. Due to the fact that plastic is non-biodegradable, it is essential that it is recycled as part of the global efforts to reducing plastic and other solid waste in the environment.

 

Process of Plastic Recycling

 

The following is a step by step process of plastic recycling:

 

  • Collection

 

Plastics are available in a number of forms for example plastic containers, jars, bottles, plastic bags, packaging plastic, big industrial plastics just to mention but a few. Due to their nature and availability, there are plastic collection centers and some business people have ventured into plastic collecting business as a source of income. Tons and tons of scrap plastic are collected and sent to a collecting yard where they are then packed and transported to plastic processing plants. Unfortunately, not all countries have the capacity to recycle plastic. Very few developing countries can actually recycle plastic. This means that, plastic waste is still a major problem to some countries in the world.

 

  • Sorting

 

The actual plastic recycling process starts with sorting of the different plastic items by their resin content and color. This process is also done to ensure all contaminates are eliminated. There are specially designed machines that help in sorting of the plastics according to their resin content. Then the recycling mill sorts the scrap plastic by symbols at the bottom of the plastics.

 

  • Shredding

 

After sorting the plastics, the next step is to cut the plastics into tiny chunks or pieces. The plastic bottles and containers are then ground and cut into tiny pieces or flakes. The heavier and lighter plastic flakes are separated using a specially designed machine. The separation process helps in ensuring that the different plastics are not put together or mixed up in the final product. Remember that different plastics are used to make different items.

 

  • Cleaning

 

After a complete separation, the flakes or chunks are then washed with detergents to remove the remaining contamination. Once the cleaning process is complete, the clean flakes are passed through specialized equipment that further separates the plastic resin types. The plastic flakes are then subjected to moderate heat to dry.

 

  • Melting

 

The dry flakes are melted down. They can be melted down and molded into a new shape or they are melted down and processed into granules. The melting process is done under regulated temperatures. There is specialized equipment designed to melt down plastic without destroying them.

 

  • Making of pellets

 

After the melting process, the plastic pieces are then compressed into tiny pellets known as nurdles. In this state, the plastic pellets are ready for reuse or be redesigned into new plastic products. It is important to point out that recycled plastic is hardly used to make identical plastic item or its previous form. It is in this pellet form that plastics are transported to plastic manufacturing companies to be redesigned and be used in making other useful plastic products.

 

Advantages of Recycling Plastics

 

Plastics should be recycled because of a number of reasons as can be seen below:

 

  • Provision of a Sustainable Source of Raw Materials
  • Reduces Environmental Problems
  • Reduces Landfill Problems
  • Consumes Less Energy
  • Encourages a Sustainable Lifestyle among People

 

In summary, any sort of effort aimed at saving the environment is very important and matters a lot. Since its inception during the environmental revolution in the late 1960s, plastic recycling is one of the most encouraged solid waste management programs in the world. Prior to the push to use of plastic containers by manufacturers, products were packaged in glass, metal and paper. Therefore, in order to keep our environment clean, reduce landfills, provide a sustainable supply of plastics to manufacturers, it is important to recycle plastics.

 

Song Ming Machinery Industries Co., Ltd. is a professional manufacturer of PVC pelletizing plants. They are not only reputable for its pelletizing extruders, it also has the best credentials in the plastic recycling peripherals such as granulators, mixers, ribbon blenders, and knife grinders. “Contributing to the World through Recycling plants”, it is their goal.

Everything You Need To Know About CNC Equipment

Posted on by

CNC machines are electro-mechanical devices that manipulate machine shop tools using computer programming inputs. Did you know? The name “CNC” actually stands for Computer Numerical Control and it represents one of two common methods to generate prototypes from a digital software file.

 

The first CNC equipment was developed in the 1940s and 50s and relied on a common telecommunication data storage technology known as “punched tape” or “perforated paper tape.” Punched tape technology is long obsolete as the data medium quickly transitioned to analog and then digital computer processing in the 1950s and 1960s.

 

How Does CNC Equipment Works:

 

Machining in general is a way to transform a stock piece of material such as a block of plastic and arrive at a finished product (typically a prototype part) by means of a controlled material removal process. Similar to the other prototype development technology, FDM (3D printing), CNC relies on digital instructions from a Computer Aided Manufacturing (CAM) or Computer Aided Design (CAD) file like Solidworks 3D. The CNC machine interprets the design as instructions for cutting prototype parts. The ability to program computer devices to control machine tools rapidly advances shop productivity by automating the highly technical and labor intensive processes. Automated cuts improve both the speed and the accuracy with which prototype parts can be created – especially when the material is critical (such as is the case with polypropylene – read more about polypropylene).

 

Oftentimes machining processes require the use of multiple tools to make the desired cuts (e.g. different sized drill bits). CNC equipment commonly combines tools into common units or cells from which the machine can draw. Basic machines move in one or two axes while advanced machines move laterally in the x, y axis, longitudinally in the z axis, and oftentimes rotationally about one or more axes. Multi axis machines are capable of flipping parts over automatically, allowing you to remove material that was previously “underneath.” This eliminates the need for workers to flip the prototype stock material and allows you to cut all sides without the need for manual intervention. Fully automated cuts are generally more accurate than what is possible with manual inputs. That said, sometimes finishing work like etching is better accomplished by hand as well as simple cuts that would require extensive design work to program the machine for automation.

 

Want to learn about the different types of CNC equipment? Read more below.

 

Types of CNC Equipment:

CNC machines typically fall into one the two general categories: conventional machining technologies and novel machining technology:

 

Conventional Technologies:

 

  • Drills:

Drills work by spinning a drill bit and moving the bit about and into contact with a stationary block of stock material.

 

  • Lathes:

Lathes, very much the inverse of drills, spin the block of material against the drill bit (instead of spinning the drill bit and putting it into contact with the material). Lathes typically make contact with the material by laterally moving a cutting tool until it progressively touches the spinning material.

 

  • Milling Machines:

Milling machines are probably the most common CNC equipment in use today. They involve the use of rotary cutting tools to remove material from the stock unit.

 

Novel Technologies:

 

  • Electrical and/or Chemical Machining:

There are a number of novel technologies that use specialized techniques to cut material. Examples include Electron Beam Machining, Electrochemical machining, Electrical Discharge Machining (EDM), photochemical machining, and Ultrasonic machining. Most of these technologies are highly specialized and are used in special cases for mass-production involving a particular type of material.

 

  • Other Cutting Mediums:

There are a number of other novel technologies that use different mediums to cut material. Examples include laser cutting machines, oxy-fuel cutting machines, plasma cutting machines, and water-jet cutting technology.

 

Materials Used:

Almost any material can be used in a CNC equipment. It really depends on the application. Common materials include metals such as aluminum, brass, copper, steel, and titanium, as well as wood, foam, fiberglass, and plastics such as polypropylene.

 

Application for Rapid Prototyping:

CNC equipment was the first major break-through in the field of rapid-prototyping. Before numerical control (in the case of punched tape technology) and computer numerical control (with analog and digital computing), parts had to be machined by hand. This invariably led to larger margins of error in end prototype products and even more so if/when machines were manually used for larger scale manufacturing.

 

Application for Manufacturing:

Many novel CNC specialty machines are built specifically for niche manufacturing processes. For example, electrochemical machining is used to cut highly durable metal products not otherwise feasible. Conventional CNC equipment is more adept at and typically used for prototype development than manufacturing.

 

By the way, when mentioned CNC equipment, I recommend that you can try to visit the website of SEHO Industry Co., Ltd. if you need more information about CNC machinery. SEHO is the professional supplier of specializing in new or used CNC machinery. They adopt stock supply, you can visit their website to check out the machines that can quickly meet your demands of urgent orders. Now, to obtain further details about excellent CNC equipment, please don’t hesitate to contact with SEHO.

No Machines Are Called Shoe Manufacturing Machines?!

Posted on by

Someone will need to buy shoe-manufacturing machines to make sandals, heels, and boots. However, they don’t know what they are called because running a “shoe making machine” query on Google simply isn’t working. In this article, I will tell you something about “shoe manufacturing machines”.

 

First and foremost, there is no “shoe making machine” as such.

 

Shoes are made on several machines including gluers, injection molders, sole makers, toe binders, riveters, upper stretchers, lasts, heat curing ovens, sewing machines, and more. There’s no one machine where you dump in plastic pellets, a square of leather and a buckle and a perfectly finished sandal is spit out the other end. There are lots of steps-each step requires a different machine and there’s some hand work too. Rivets are set by a worker using a riveter. Uppers are sewn by a skilled operator on a special sewing machine designed for sewing uppers. Soles are glued down and cured in a heat treater. So the machines you see are used for making shoes -even if they aren’t called “shoe manufacturing machines”

 

Integral Parts of The Process in Footwear Manufacturing

 

You might want to become a bit more familiar with the tools, words and terminology and machines used in making shoes. Several fashion colleges have programs for shoe and footwear design starting with design and moving into making shoes and manufacturing processes. You will learn the way they are made and the correct words for each step in manufacturing. Speaking of words -change your search terms: you will have better luck searching for footwear manufacturing equipment and supplies. Again you will find injection molders, sewing machines, heat treaters, cement lasters, leather cutters, skivers, lasting equipment, belt solers, sanders, and band saws, welt stitchers, and more. While none are called “shoe making machines” all are integral parts of the process in footwear manufacturing.

 

To start you might want to learn custom shoemaking – this is far more doable with less investment. You can start by getting a job in a shoe repair shop and learning the equipment, how it works, what tools are essential (lasts are the most important piece of equipment and/or tool used in making shoes) what goes into making high quality shoes, and how to make and repair shoes. Or look for a custom footwear maker/seller and work there. Learning from a master is a time honored method of learning a skill. When you know what you need from seeing what the master crafts-person uses you can find the specific machinery you need.

 

Find Out The Right and Suitable Shoe Making Equipment

 

There are courses in custom footwear and shoe-making -these will help you get a handle on the tools, machinery and the process used in making higher quality footwear. Custom shoe-making can be done in an artisan workshop setting: high fashion shoes and boots made mostly by hand in small quantities can be sold for higher prices and for high profits -and with time you can start to make a name for yourself the same way people like Ferragamo and Louboutin started. Again you won’t find anything labeled “shoes making machine” but you will find lasters, stitchers and more and you will know why these machines are what you are looking for.

 

MINZ Inc. divided shoe making equipment into three parts, one is shoes cutting machine including plane type cutting machine and traveling head type cutting machine, another is cutting machine energy saving system, and the other is automation development equipment. Their average energy saving is 70~90% comparing to traditional power system. When the machine is not cutting, it generates zero noise, and the temperature of hydraulic fluid and motor are reduced half.

 

If you are interested in learning further details about related shoe making equipment, please feel free to send inquiries or contact with MINZ.
