An Introduction to Precision Machining Services and CNC Machining

Posted on by

From a simple coin and electronics we use every day to parts of an airplane, everything comes from a very sophisticated process known as the precision technology service. It is a process of removing materials from a workpiece while gripping close to great finishes. This precision machining service has many types, which include machining, milling, electrical discharge and tuning. Nowadays most manufacturing companies use advanced precision machining performed by an EDM machine. Generally, however, high precision lathes are controlled by the use of CNC or Computer Numerical Controls.

 

A precision technology service contributes to each and every object that we see. Most metal products go through precision machining to achieve consistent, quality products usually from intricate blueprint designs. Also, wood and plastic materials use this machining method operated by highly trained and specialized machinists. The process in precision machining involves cutting tools, which are responsible for removing material from a workpiece. For the tool to do its cutting properly, it moves in a specific direction for a correct and precise cut. This main motion is what we call the cutting speed. The secondary motion is called feed in which the workpiece can be moved while in the process. Simultaneously, the motions and sharpness of the tool allow the precision machining service to operate.

 

One type of precision technology service is a milling machine, which shapes and cuts materials. This machine can either be horizontal or vertical based on the spindle orientation. It works in a manner wherein both the milling cutter and the workpiece move, which is controlled mechanically, manually or controlled by a CNC milling machine. One advanced milling machining used by most manufacturing companies is the CNC Milling Machine. It is mainly controlled by a computer and is normally used with horizontal or vertical milling machines and can also move the shaft along the Z axis. The first CNC machine, eventually called NC (Numerically Controlled) machine, was made in the 1940s. The CNC machining of today work with Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) softwares.

 

The lathe machine was dated back to ancient Egypt. As years passed, it has transitioned from something made out of wood, to something made of metal. Nowadays, lathe machines are operated by a computer. In some countries where technology is advanced, a CNC Lathe Machine is used. It is a lathe machining in which it is controlled by computers. Thus this method generates more varieties of dimensions, features and shapes while holding very close tolerance.

What Are the Different Types of Plastic Raw Materials?

Posted on by

There are hundreds of different types of plastic raw materials. Additionally, each type of plastic may vary in certain specifications, such as density and strength. By definition, plastics are able to be molded, so most plastic raw materials are available in various forms. The choice of plastic rolls, sheets or pellets is usually determined by the type of molding machinery used by product manufacturers. Selection of which plastic compound to use is a matter of what properties are desired in the finished product.

 

Plastic is an organic polymer. Chemically, most are very long chains of repeating hydrocarbons, consisting exclusively or primarily of hydrogen and carbon atoms. There are a few plastics, still relevant to modern civilization, made from very natural organic sources. Rubber is made from the sap of a plant; celluloid is made from cellulose, the ingredient that gives all plants their structural form. The majority of plastics in the modern world have been made from petroleum oil or natural gas.

 

Recyclable plastics are called thermoplastics because their chemical structures are the same in both solid and hot molten states. Less common thermosetting plastics establish their permanent structures once solidified. Plastic raw materials can also be categorized according to whether their polymers line up in an orderly, almost crystalline matrix, or else in a more random, or amorphous structure.

 

When it comes to plastic raw materials, a manufacturer’s buying decision is principally based on the physical requirements of the product they are making. There are many different types of plastic precisely because each has a different mix of properties. Disposable polyethylene (PE) bags are relatively lightweight, but they tolerate a great amount of stretch before easily tearing apart. High density polyethylene (HDPE), on the other hand, is well-suited to form into beverage bottles. Low density polyethylene (LDPE) is particularly tolerant of cold temperature and is often used in furniture and building materials.

 

At the other end of the scale, polyamides (PA) such as variants of Nylon® can withstand very high temperatures and is therefore used for applications such as insulation and mechanical parts. Other technical specifications of a given plastic include its flexibility and elasticity. These variables determine whether a product should be made with polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), or another plastic. Some types of specialized plastic were custom formulated to a single product’s specifications.

 

Plastic raw materials come in many different forms, and this choice is also made in part on the intended product. Bags are made from rolls, for example. More often than not, the choice is influenced by the type of molding equipment the manufacturer employs. Raw plastic in sheet form are needed for compression-molding and vacuum-molding equipment, whereas rods and bricks are fed into most extrusion-molding machines. Small pellets, which are usually the form of any recycled plastic supply, are the preferred form for injection-molding equipment.

 

Prochase Enterprise Co., Ltd. not only provides protective film series products, also offers plastic raw materials to clients.

The History of Barbed Wire

Posted on by

Life in the American West was reshaped by a series of patents for a simple tool – barbed wire – that helped ranchers tame the land. Patents for improvements to wire fencing were granted by the U.S. Patent Office, beginning with Michael Kelly in November 1868 and ending with Joseph Glidden in November 1874, that shape the history of this tool.
Barbed Wire

THORNY FENCE VS. WILD WEST

The swift emergence of this highly effective tool as the favored fencing method changed life in the Wild West as dramatically as the rifle, six-shooter, telegraph, windmill, and locomotive.

 

Without fencing, livestock grazed freely, competing for fodder and water. Where working farms did exist, most properties were unfenced and open to foraging by roaming cattle and sheep.

 

Before barbed wire, the lack of effective fencing limited farming and ranching practices, and the number of people who could settle in an area. The new fencing changed the West from vast and undefined prairies/plains to a land of farming, and widespread settlement.

 

WHY USE WIRE?

Wooden fences were costly and difficult to acquire on the prairie and plains, where few trees grew. Lumber was in such short supply in the region that farmers were forced to build houses of sod.

 

Likewise, rocks for stone walls were scarce on the plains. Barbed wire proved to be cheaper, easier, and quicker to use than any of these other alternatives.

 

MICHAEL KELLY – FIRST BW FENCING

The first wire fences (before the invention of the barb) consisted of only one strand of wire, which was constantly broken by the weight of cattle pressing against it.

 

Michael Kelly made a significant improvement to wire fencing, he twisted two wires together to form a cable for barbs – the first of its kind. Known as the “thorny fence,” Michael Kelly’s double-strand design made fences stronger, and the painful barbs made cattle keep their distance.

 

JOSEPH GLIDDEN – KING OF THE BARB

Predictably, other inventors sought to improve upon Michael Kelly’s design; among them was Joseph Glidden, a farmer from De Kalb, IL.

 

In 1873 and 1874, patents were issued for various designs to compete against Michael Kelly’s invention. But the recognized winner was Joseph Glidden’s design for a simple wire barb locked onto a double-strand wire.

 

Joseph Glidden’s design made barbed wire more effective, he invented a method for locking the barbs in place, and invented the machinery to mass-produce the wire.

 

Joseph Glidden’s U.S. patent was issued November 24, 1874. His patent survived court challenges from other inventors. Joseph Glidden prevailed in litigation and in sales. Today, it remains the most familiar style of barbed wire.

 

BW IMPACT

Living patterns of the nomadic Native Americans were radically altered. Further squeezed from lands they had always used, they began calling barbed wire “the Devil’s rope.”

 

More fenced-off land meant that cattle herders were dependent on the dwindling public lands, which rapidly became overgrazed. Cattle herding was destined to become extinct.

 

BW & WARFARE & SECURITY

After its invention, barbed wire was widely used during wars, to protect people and property from unwanted intrusion. Military usage of barbed wire formally dates to 1888, when British military manuals first encouraged its use.

 

During the Spanish-American War, Teddy Roosevelt’s Rough Riders chose to defend their camps with the help of barbed fencing. In turn-of-the-century South Africa, five-strand fences were linked to blockhouses sheltering British troops from the encroachment of Boer commandos. During World War I, barbed wire was used as a military weapon.

 

Even now, barbed wire is widely used to protect and safeguard military installation, to establish territorial boundaries, and for prisoner confinement.

 

Used on construction and storage sites and around warehouses, barbed wire protects supplies and persons and keeps out unwanted intruders.

Public Seating Is Not Only For the Public but Also For Your Business

Posted on by

Public seating serves only one function, and that is to seat the public. It can be in open or closed spaces, indoors or outdoors. The public cannot be expected to think that having seating is a guaranteed right, but it does help if the seating is comfortable and made memorable by its construction and design.

 

Public seating can be used for many different purposes. It can be used to make a statement, and this is one of the areas where design firms can use public seating to their advantage. In open outdoor spaces, where there is little concern for matching or complimenting decors, a strategically placed custom- designed setting can be used as to drawn attention to design capability, products or services. While there are no legal requirements or legislation for seating in the public sector, there are some regulations that should be followed when seating is installed in commercial enterprises.

 

Since public seating is not a guaranteed right, there can be some open discussions concerning the use. If it is installed indoors as a courtesy to your visitors, you are free to do whatever you wish with it, but there are a few precautions. Your primary concern will be that of the quality. Over the life of your establishment, there may be thousands of people who will visit your premises, and your seating should be constructed to handle the heavy use.

 

In the U.S., seating that meets the Business and Institutional Furniture Manufacturer’s Association American National Standards Institute/ (ANSI/BIFMA), is certified as meeting performance requirements. Metals such as steel and aluminum usually last longer, and injected-molded foam cushions are likely to retain their shapes for longer periods. It may be better to avoid cloth or similar fabrics, because they are difficult to clean, and degrade quickly with frequent use.

 

There is no reason why your seating should not be comfortable. Although your concern may initially be that of durability, your visitors will be impressed and retain a more favorable impression with comfortable seating. You can offer as many accessories that you consider appropriate, such as matching end tables, and arm rests. Many of your visitors may also appreciate attached cup holders and a special touch can include power outlets for charging and operating mobile electronic gadgets such as cell phones and tablets.

 

The arrangement and layout of the seating governs the functioning. Some degree of flexibility may be desirable, as changes may be sometimes necessary. Your system should be easy to re-arrange in different configurations, and one of the most efficient ways to do this is to use a modular design that allows you to place or replace parts independently.

 

What is achieved with your public seating system will depend on your supplier. A solid trusting relationship forms the base for achieving satisfactory results. Many suppliers may have the expertise in design architecture, engineering and manufacturing of seating for public places, but they may lack the necessary skills that relate to developing relationships. As a result, you may not feel comfortable, working with ineffective communications or poor explanations.

 

You can help the perception of your business with public seating. There should be some careful planning when buying public seating for your business. You can try to visit the website of VOXIM Co., Ltd., the professional manufacturer of public seating.

 

Ergonomic design and comfort with vast range of options makes this the ergonomic public seating choice for any type of facility requirement. VOXIM offers various types of public seating to satisfy different needs!

How Does a Surface Grinder Work?

Posted on by

Basics

A surface grinder is a device that is used to accurately and intricately remove unneeded layers from a surface in an effort to smooth the target layer. The reason that a surface grinder is used is that it provides a great level of accuracy and detail that is sometimes difficult to achieve by hand. The use of a surface grinder is concentrated in heavy industry, especially in the automotive industry. Surface grinders are used on various types of metal and woods. The surface being worked on is directly related to the blade being used as they are specialized for different surfaces. This is a better option than trying to grind a surface by hand as it is less time consuming.

 

The amount of time it takes to grind a surface depends on the skill of the user and the surface being ground. The best safety guideline with a surface grinder is to take your time. Most accidents happen by using the wrong blade with the wrong material or running the blade on the grinder faster than the speed it was meant to run at. A surface grinder can be used to prepare surfaces such as floors and sheet metal for cars.

 

How It Works

The typical surface grinder has a table that is capable of moving forward and backward as well as side to side. When moving side to side, the table uses hydraulics to move. The machine also has a grinding wheel that rotates and has an adjustable height. The grinding wheel is generally made of diamond, aluminum oxide, silicon carbide or cubic boron nitride. The majority of surface grinders used in the modern era are at least partially automated. The work material is held on the table of a magnetic chuck and sometimes an electro-magnetic chuck depending on the specific machine.

 

What a Surface Grinder Does To Material

A surface grinder produces a high level of heat which will create stress on the material. After being run through a surface grinder, a material will be more apt to breakage or fracture than before it was run through the machine. A material can also lose its magnetic properties if its temperature is raised too high.

 

Tong Yi Machinery Inc. is the professional surface grinders manufacturer in Taiwan. Kinds of surface grinding machine series all can be provided by them. If you need further details about surface grinders, welcome to browse Tong Yi’s website or contact with them via email or telephone!

Protect Your Diesel Forklift Trucks from ‘Bad’ Fuel

Posted on by

Tackling chemical effects, water and microbes

Diesel is one of the materials handling industry’s most basic requirements, but like other fuels it deteriorates with age. Chemical degradation, contamination with water and infestation with microbes can turn it into an unhealthy cocktail that damages your forklift trucks and your operation.

 

At best, ‘bad’ diesel reduces the efficiency of your lift trucks’ performance. At worst, it causes serious and expensive damage. If you think you can avoid this by buying only ‘good’ diesel, you are mistaken. The changes that turn good diesel bad usually take place on your own premises.

 

Suppliers of diesel in the EU and other economically developed regions are governed by rules on its quality, content and storage, so you can expect it to reach you in good condition. Always buying from a supplier with a good reputation lessens the risk of careless handling and storage in the supply chain from the refinery to your business. The differences between brands of diesel tend to be in the mix of additives used.

 

The problems

Even under the best conditions, chemical activity will eventually change the nature of stored diesel. The products of that chemistry include solid materials which form a slimy layer on surfaces and sludge at the bottom of tanks. Water is bad news for engines on its own, but it also encourages microbial growth which speeds up the chemical degradation.

 

Let’s look at each of those interacting factors in turn to see where they come from and what effect they have. As soon as diesel is exposed to air it reacts chemically. This starts off chain reactions that result in more and more undesirable molecules and solid breakdown products. As well as causing blockages, these substances are often corrosive. If you store diesel, they can become a problem within a few months – and even sooner if water and microbes increase their production.

 

Diesel can become ‘wet’ through leaks in storage tanks and absorption from a moist atmosphere. Water in diesel is directly damaging to some engine components and it interferes with fuel combustion. It also reduces the fuel’s lubricating effect, exposing engines to excess wear and damage. In a metal storage tank, water can lead to corrosion and further contamination. In addition, the presence of water helps microbes to thrive.

 

Diesel is an organic substance which can be used as food by a variety of bacteria, fungi and yeasts. Arriving via the air, in moisture or from a contaminated supply, these microbes can multiply hugely. Their acidic by-products, along with the slime created by their own biomass and by breakdown of the fuel, can be highly damaging. They form a layer or biofilm on surfaces, often collecting in pits and crevices where their corrosive effect becomes even more concentrated.

 

Slime and sludge produced by these factors blocks filters and fuel lines, while the acids affect engines, fuel systems, storage tanks and any other vulnerable surfaces coming into contact with them. Combustion efficiency decreases, engine life is shortened and bills for replacing components become more frequent. Once microbes have infected a diesel forklift truck they are very difficult to eradicate.

 

For completeness, it should be mentioned that other materials can contaminate fuel. Abrasive particles of rust, dirt and sand are particularly to be avoided in engines.

Before discussing solutions to diesel problems, it is worth noting that the composition of this fuel has changed over the years and is likely to continue changing.

 

Regulations on reduction of sulphur, to clean up exhaust emissions, have led to the use of ultra-low sulphur diesel (ULSD). Sulphur increases the lubricant properties of diesel, so engines using ULSD may wear more quickly.

 

Throughout Europe, biodiesel (biologically produced diesel) is now blended with the fuel to improve lubrication. Unfortunately biodiesel breaks down more quickly, absorbs more water and is more hospitable to microbes. With biodiesel, even greater care must be taken to protect the fuel from contamination.

 

The solutions

The first steps toward avoiding diesel quality problems are to buy it from a reputable supplier, as already mentioned, and to store it in suitable, well-maintained tanks. Regulations on storage of diesel vary a little between countries in Europe and mainly concern the potential environmental impact of leaks reaching water bodies and other natural habitats. For diesel users, avoiding the loss of expensive fuel should be a strong enough incentive to ensure vigilance against leakage.

 

Safety legislation is stricter for petrol than for diesel, but it must always be remembered that all fuels are flammable. Keeping storage tanks away from sources of heat is essential, and a cool environment also helps in maintaining the diesel’s condition.

 

Some people may believe that the fuel filter in their diesel forklift truck’s engine will remove any contamination. This is unlikely. The fuel you put into the truck must be kept clean and in good condition within the storage tank. If diesel is stored at a low temperature, and certainly below 70 ºF (21 ºC), and care is taken to avoid contamination, it should last for a few months. To extend its life further, fuel stabilisers, biocides and other treatments may be needed.

 

A storage tank should be regularly checked for any defects that could let diesel leak out or water leak in, while openings should be water-tight and caps should be secured. The space between the fuel and the top of the tank is filled with air, which can be a source of moisture. Ideally that space should be kept to a minimum, allowing only enough for expansion of the fuel. This is another good reason for topping up frequently with fresh diesel from the supplier rather than storing large amounts.

 

A variety of fuel stabilisers can be bought for use if diesel has to be stored for relatively long periods. Regular, routine testing of stored fuel for water and microbial contamination is a sensible precaution. Simple-to-use test kits are available for this. The sooner these problems are detected, the easier and less costly they are to tackle.

 

If fuel is heavily contaminated by microbes, a large dose of biocide can be used to kill them. The dead bodies of the microbes, along with the solid material they have helped to create, need to be filtered out before the fuel is fit to use. Killing all of the microbes is difficult when they are living deep within slime and sludge, so biocide treatment will not work unless the storage tank is thoroughly cleaned.

 

Simple measures to reduce contamination risks include using a filter whenever moving fuel from one storage vessel to another, or into the tank of a forklift truck, and always doing this in a dry, dirt-free place. At the other end of the scale, for operations that really do require long-term storage of diesel in large quantities, there are specialists who can supply automatic systems for cleaning and removal of solids, water and microbes. Having invested heavily in your diesel forklift trucks and your business, it makes absolute sense to protect them.

How to Clean Different Outdoor Furniture Fabric

Posted on by

Outdoor furniture is designed with durability and longevity in mind, as it has to battle the elements of a patio, backyard, or deck. Designers have created unique fabric blends to resist fading, tearing and to be easy to clean after long periods of storage. There are several types of materials commonly used in outdoor furniture, and each requires a different level of care and cleaning routine.

 

Solution-Dyed Acrylics

 

Commonly used for softer, more pliant pieces of furniture, solution-dyed acrylics are commonly used for outdoor pillows, umbrellas, and awnings. To create this type of fabric, the acrylic is formed in to colored fibers prior to becoming thread and dyed prior to being woven into cloth. This chemical treatment makes the material water-resistant and provides a better colorfast, which means the fabric is far less likely to bleed color when wet. According to a home-guide on SFGate, to properly clean this soft, breathable material, use a mild, soapy solution in warm water. Easily wipe away any dirt or mildew with a soft sponge or cloth.

 

Acrylic-Coated Polyesters

 

Polyester is a durable, man-made material which is commonly used in protecting outdoor furniture, especially due to the availability of many color choices. Unlike the solution-dyed acrylic fabric, this type of fabric is woven prior to being dipped into a colorful acrylic coating. This type of material is also available as a polyester-cotton blend, and most commonly used in protective covers for automobiles and watercraft. To clean this material, shake or vacuum loose dirt or debris from the fabric before using a mild soap with lukewarm water to wash and rinse clean. The fabric should be allowed to air dry and properly breathe in order to prevent growth of mold or mildew.

 

Vinyl-Coated Synthetic Fibers

 

Also known as PVC mesh, this type of fabric is most commonly used in outdoor hammocks and sling-style chairs due to its strength and durability. PVC mesh is created from polyester or acrylic yarns which have been coated in vinyl for a strong, non-stretching material that is intended to support the weight of an individual. Vinyl-coated synthetic fibers are colorfast and easily cleaned with a cloth, lukewarm water, and a mild powdered soap solution. Avoid acid-based or vinegar-containing cleaning solutions, as these may damage the mesh. Never use an iron or heat exceeding 150 degrees as this may cause melting or warping of the material. Due to the combination of durable, water-resistant fabrics, PVC mesh is also mildew-resistant.

 

Synthetic Fabric

 

Other types of pliable, synthetic materials used in outdoor furniture include those designed to protect from fading and sun damage. Furniture covers and umbrellas take the brunt of the elemental beating, and have been designed to stand up to the harsher conditions which affect an outdoor space. According to Terra Patio, who specialize in outdoor furniture, to properly clean these types of fabrics, immediately brush off accumulated dirt and spot-clean spills quickly to avoid staining. Avoid cleaning products which contain bleach, as they may discolor the fabric, and do not use detergents. Mild dish soap and lukewarm water should suffice in caring for the area. Avoid using an iron or steamer on the synthetic fabric as it may warp or melt. Air dry for best results.

 

Olefin

 

Olefin is a man-made material related to plastic which is created by heating polyethylene (or other petroleum-based compounds) and pressed in to a spinneret to create long fibers. Olefin is manufactured in a similar style to other man-made fabrics such as nylon or polyester, but has a much smoother texture. Olefin is used in furniture such as lawn chairs and outside carpeting due to its quick-drying and weather-resistant properties. It is also stain and mildew-resistant, making it a great fabric for the outdoors. To clean Olefin, wipe off or vacuum dirt particles before using a mix of bleach, dish detergent, and warm water. Saturate the fabric with the solution and rinse well.

 

Properly caring for outdoor furniture increases the longevity of the pieces, protecting against mold, dry rot, and damage due to adverse weather conditions. Although the fabric used in the manufacture of outdoor furniture is more durable than those intended for exclusive indoor use, homeowners should properly clean and store their patio furniture when not being used for an extended period of time.

What is a Pressure Control Valve and Why Do You Need It?

Posted on by

Pressure control valves are found in virtually every hydraulic system, and they assist in a variety of functions, from keeping system pressures safely below a desired upper limit to maintaining a set pressure in part of a circuit.

 

Every pressure control valve switches (or controls) at a predetermined pressure setting. The switching pressure is generally a variable setting on the valve itself. A change in position of the pressure control valve (i.e. open or closed) occurs either gradually (by control) or suddenly (by switch). Pressure shut-off valves and pressure sequence valves are hydraulic valves with a fixed throttle whereas relief and reducing valves are hydraulic valves with a variable throttle.

 

Pressure valves are hydraulic valves that gradually (control) or suddenly (switch) change in position.

 

The most common types of pressure control valves are the pressure relief valve and the pressure reducing valve. Pressure relief valves control the system pressure by relieving part, or all, of the flow to tank. Pressure reducing valves reduce the pressure supplied to a sub-system of a hydraulic system. Sequence valves are used to direct the flow to a secondary circuit. Unloading valves are used to direct flow to tank at pre-set system pressure.

 

Type of Pressure Control Valves

 

  • Pressure valves, relief function
  • Pressure valves, reducing function
  • Pressure valves, fixed throttle

 

A hydraulic system can only function – as per requirements – by using valves. Thus, you should always look for the correct type of hydraulic valve to serve your intended purpose. You can try to browse the website of ASHUN, the professional hydraulic valves manufacturer in the industry, to get more information about pressure control valves. If you have any questions, welcome to contact with ASHUN via email or telephone!

Difference between Manual Thermostats and Electrical Thermostats

Posted on by

A thermostat is a temperature–sensitive device that turns HVAC systems on and off when the temperature of an environment reaches a preset level. Essentially, it turns on the air conditioning when it gets too warm, or the heating when it gets too chilly. Thermostats control the workings of comfort systems by directing energy to the appropriate system when needed. When selecting a thermostat, property owners can either go for simple manual thermostats or sophisticated electronic thermostats that provide improved functionality and highly efficient operations. Thanks to the easy to understand packaging and universal compatibility, choosing a thermostat is easy.

 

Systems that Use a Thermostat

Single–stage heating systems have one electrical or gas heating device, which may consist of a heater or an AC device as well. Most units that use natural gas provide single–stage heating. Usually, a single–stage thermostat should have room for three wires if the system handles heating only. However, if the system handles heating and cooling, the thermostat will have to accommodate five wires or less.

 

Multi–stage systems have a standard electrical or gas heating device as well as an emergency and/or auxiliary heating device. The emergency or auxiliary heating kicks in when temperatures drop faster than the standard heater can handle, or if the standard heater fails. Line voltage systems, on the other hand, use direct current. Homeowners should choose line voltage thermostats that can handle additional conducted power.

 

Difference between Manual and Programmable Electrical Thermostats

 

Electromechanical or annual thermostats are the traditional mercury units that have internal coils to contract and expand in response to changes in temperature. They are becoming obsolete because of two main reasons:

 

  • Products containing mercury are banned or restricted in most states
  • Programmable thermostats are more accurate and sensitive to temperature changes

 

However, manual thermostats are still popular due to their ease of use, low cost, and the familiarity of their controls.

 

Digital manual thermostats use an electronic sensor to register temperature changes in an environment and then compare those changes to the preset settings. If there is a difference, the thermostat sends a warning to the cooling or heating system that immediate action is required. However, users still have to physically adjust the settings to their preferred level.

 

Programmable electrical thermostats are an upgrade from the manual thermostats. In addition to saving energy costs, they allow homeowners to program their preferred temperature settings into the unit’s memory, along with the time of day they would like the changes to occur.

 

For most homes, a pre–programmed electrical thermostat does not need any adjustment. Homeowners simply need to install it and they are ready. When determining the right thermostat, homeowners should consider the flexibility and functionality they need from day to day.

 

Alpha Brass electrical thermostats are manufactured and calibrated with precision to provide accurate temperature points. These thermostats are snap-acting and the temperature is controlled by signal interrupting the gas flow to the burner. If you need further details about our electrical thermostats, welcome to browse our website or contact with Alpha Brass directly!

How to Use Metal Eyelets?

Posted on by

Sometimes you see projects and they just don’t look finished. They are probably fine the way they are, but a little dressing up never hurt anything, right? One of the ways you can dress up plain punched holes is with eyelets. They aren’t hard to use when you know how, so here are a few tips to get you started!

 

There are several sizes of scrapbooking eyelets, such as 1/8″ and 3/16″. This size refers to the hole in the center of the eyelet, not the outside diameter of the design. They come in all shapes and sizes, similar to scrapbooking brads.

 

One question I get asked a lot is, “are these for use on cloth or clothing?” Certainly we all see metal eyelets all the time on curtains, hats, belts, and on shoes & hoodies where the strings go through. Generally, these are a sturdier type of eyelet than scrapbooking eyelets and they have to be attached with a special setter that can go through thick materials. So while you might be able to use scrapbooking eyelets on cloth, they probably won’t stand up well to the harsh environment of wear and washing for very long.

 

Scrapbooking eyelets are usually a weaker metal than clothing eyelets and can easily be attached with a simple metal setter and a craft hammer. There are even eyelets that can be set with a ball point pen tip. They are called Quicklets and are made by Eyelet Outlet. The metal is very soft and is scored so that the back flattens easily when pushed on firmly with a pen tip.

 

Depending on your budget, there are several types of eyelet setters available on the market. There are silent setters which are a spring-loaded type of setter, the crop-a-dile, a squeeze type of tool, but most common and economical is the eyelet setter tool. An eyelet setter is a metal took about 5″ long with a special tip that fits into the hole on the back of the eyelet.

 

To set a metal eyelet, simply make a small hole in your paper and place the eyelet through the hole. Then turn the paper & eyelet over onto a firm surface. Place the tip of the setter into the hole, Give the top of it a firm whack or two with a craft hammer. That’s it! The back of the eyelet will splay out holding the eyelet in place. If you need a neat appearance on the backside of your project, consider buying finishing washers or rivets. They are placed on the back of the eyelet before setting it.
