Lots of elastane in the products, and do you know why and how it effects the products?

Posted on by

Elastane was developed as an alternative to rubber in the 1950’s and is a thermoplastic polyurethane synthetic fiber. The unique property of this elastomer, as a result of its randomly coiled polymer structure made up of a mix of stiff and flexible segments, is that it can be stretched 500% or more without breaking or permanently deforming. Giving it the well-known characteristic of the ability to revert to its original shape after being stretched. The long amorphous segments in elastane create the elastic properties and the short rigid segments provide the structure when the fiber is stretched and released. Elastane has the highest stretch tension of all textile raw materials.

 

Elastane is soft, lightweight and abrasion resistant. Elastane is used where a high degree of permanent elasticity is required, as in tights, sportswear, swimwear and in woven and knitted fabrics. Adding elastane just for couple of percent makes fabrics more comfortable to wear. Elastane is always used in a blend with other fibers.

 

Elongation on an elastane yarn is much higher than on a more rigid yarn, like polyamide on Lymed fabric. When stretching a knit, the elastane yarn would practically never get to its limits of the elongation. This means, in most cases, that the elastane would not determine the ultimate elongation in the knit- determination is made by the rigid yarns in the fabric. Also, the construction of the knit has effect on the stretchability- looser the knit, stretchier the fabric.

 

More elastane content in a fabric does not mean that the fabric will have more stretch. By increasing the elastane content in the fabric, more resistance to stretch is created using the elastomeric material. More elastane means more powerful fabric.

Main Features and Benefits of CNC Milling Machine

Posted on by

CNC (Computer Numerical Control) milling machine is one of the common machine tools in machinery industry. It is the popular form of CNC that can perform those repetitive tasks of drilling and turning that used to be human jobs long time ago.

 

CNC Mills are classified based on the number of axes that they have. Axes are labeled as x and y for horizontal movement, and z for vertical movement.

 

Basically, this milling machine has four axes which are Milling Head Z, Table Z, Table Y, and Table X. The quantity of axes it has is often presented in many different ways.

 

For example, there is a five-axis machine. The extra 5th axis is in the form of a horizontal pivot for the milling head that ensure the excellent flexibility of machining with the end mill at an angle follow the table.

 

It is usually programmed by using a series of standard commands that we named it as G-codes to represent specific CNC tasks in alpha-numeric form.

 

There are many different sizes for this machine based on the purpose and location of usage, as well as the materials that need to be cut.

 

Besides that, the size of motor affects the speed of cutting the materials. Normally, materials like plastic and wood are the easiest things to cut, unlike steel that need stronger milling machine and longer time.

 

To evaluate the performance of milling, we can look at its rigidity. For example, the more rigid a mill is, the more precisely it drills and cuts. CNC mills normally have better & tougher engines for higher rigidity compared to manual counterparts.

 

With CNC milling machine, we can improve the speed of cut compared to manual operation. It also reduced the rejection when rigidity results increased. Thus, in long run business, it will indeed save a lot of time and overhead due to less wastage happened.

 

Another benefit is the accuracy of cut through CNC milling machine with a computer numerically controlled machine. In production line, it is very important to have all the parts produced exactly the same. However, nothing is perfect. CNC milling machine may also have a possibility of fault lies in the operator due to a mill can cut with absolute precision as close as.0001 of an inch.

 

In addition, many mills have beds that are able to move at different angles for easy cutting jobs, different angled cut as well as more difficult drilling operation. This is one of the benefits over manual mills.

 

Lastly, with the automated cooling systems, it is able to maintain the quality of raw material by spraying or blasting the hot metal or even tooling with specially formulated coolant.

 

With the benefits of CNC milling machine stated above, it is really worth the money to invest a CNC milling machine for your business use. And there are the popular brands that available in the market, such as Mori Seiki, Dahlih, CNC Takang, DMTG, Mastika, HACO, Takisawa, Okamoto, Creator, Agma, L & L, Hurco, Okuma, Extron, Enshu, Equiptop, Komatsu, Jiuh Yeh.

Understand More Information About Gearedmotors

Posted on by

Adding a gear-train to the output of any motor will reduce the speed, while simultaneously increasing torque. Gearing can be added to any type of motor. There is no need to waste time designing a geartrain and sourcing all the parts. Chances are, there is a gearmotor solution that you can drop right into your design.

 

Gear train construction ranges from simple plastic drive-trains for toys to beefy metal gear-trains for extra-high-torque applications. Gear trains can be mated to brushed or brushless DC motors as well as steppers. Gear-train modules in a variety of gear ratios are available to fit standard NEMA sized steppers.

 

Applications:

  • Robot Drive Trains
  • Radio Control Vehicles
  • Cordless Tools

 

Advantages:

  • Speed Reduction – Many DC motors simply run too fast to be useful in direct-drive applications.
  • Increased Torque – A lot of work can be coaxed from a relatively small motor if fitted with a suitable gear train.

 

Limitations:

The potential downsides of adding a gear train to a motor include:

 

  • Friction – This is especially a problem with low-cost plastic gear trains used with low-voltage motors. The extra resistance can make these gear-trains balky at low speeds.
  • Inertia – This is more of a problem with metal gear-trains. All that additional rotating mass can inhibit rapid acceleration.
  • Backlash – Any sloppiness in the gear-train tolerances create slack that must be taken up whenever the direction reverses. This can be a problem in precision motion control applications.

 

High-end precision gear-trains can be optimized to minimize any or all of these disadvantages. But be prepared to pay a premium price for them!

 

Hsiang Neng’s geared DC motor is widely used by various applications, such as magnetic bike, vending machine, game player, instrument and appliance, massage tools, stage spinning light, auto shutter, auto mah-jongg table, medical equipment. The DC gear motor is designed and manufactured in high precision and superior quality. If you are interested in learning more information about gearmotors, welcome to contact with Hsiang Neng.

Hydraulic Modular Valves and Manifolds

Posted on by

Valves are normally mounted onto a valve skid with piping at the rear, or underneath, to allow quick changes to be made for maintenance purposes. Piping can, however, be dispensed with almost totally by mounting valves onto a manifold block- with interconnections formed by drilled passages in a solid block or by cut-outs on a plate-formed manifold.

 

Modular valve assemblies allow piping to be reduced still further. These follow standards laid down by the Comit~ European des Transmission Oleophydrauliques et Pneumatiques and are consequently known as CETOP modular valves.

 

Modular valves consist of a base plate, shown in Figure 4.45a, and a wide variety of modules which may be stacked up on top. Figures 4.45b to d show some modules available. At the top of the stack a spool valve or crossover plate is fitted. Quite complicated assemblies can be built up with minimal piping and the ease of a child’s building block model.

CETOP Modular Valves

 

Mentioned modular valve, I can recommend you to visit the website of ASHUN if you are interested in learning more information about valves. Ashun was established in 1984 as a manufacturer for hydraulic and pneumatic products. For the hydraulic valves, they have 01 series modular valves, directional control valves, pressure control valves and flow control valves. Especially 01 series modular valves which can be afforded high pressure (31.5MPa) and large flow (40L/min).

Guide On How To Buy A Laser Cutting Machine

Posted on by

A laser cutting machine is a machine that uses laser lights to cut through different materials such as metal, wood, textiles, acrylic among many others. When it comes to metal cutting, you can use it to cut different types of metals such as stainless steel, steel, and aluminum.

 

Laser cutting is preferred by many people as its accuracy, has a very small kerf width, yields excellent cut quality, and has a small heat effect zone.

 

For you to buy the right machine you need to consider a number of factors:

 

Function

 

How will you be using the machine? You can use the cutting machine for two main functions: cutting and engraving. As mentioned, you can use it on different materials. The materials have different specifications; therefore, before you head to the stores you should decide on how you will use your machine.

 

Bed size

 

The bed size of the machine determines the amount of work you can do. The bed size varies from A3 to A1 where the bigger the size, the more the work that your machine can handle. The bed size is a permanent feature; therefore, you can’t change it in the future.

 

The decision should be based on the amount of work that you are planning of handling. For example, if you are planning of handling large projects you should go for a machine with a large bed.

 

Optic quality

 

The quality of the optics is the one that determines how well the machine performs. Many unknowledgeable people think that the wattage is the one that determines how effective the machine works, but this isn’t true.

 

When making the purchase you shouldn’t bother with the amount of power that the machine consumes-you should concentrate on the quality of the optics.

 

To determine the quality of the optics you should ask the seller to demonstrate how the machine works on different materials and settings.

 

Ease of use

 

If you are a new buyer you most likely don’t know how to use the laser cutting machine. A good machine should come with an easy-to-follow manual. The manual should not only show you how to use the machine, but also how to undertake minor repairs.

 

Conclusion

 

These are tips on how to buy the right laser cutting machine. Although, the machine is designed to cut different materials, you should avoid cutting plastic with it as plastic tends to give off chlorine gas which is harmful when you breathe it.

The mini lathe machine will usually incorporate both CNC technology and manual operation. Not only is this a great learning machine, but it also works well for the hobbyist.

 

Lathe machines are designed to operate with wood, aluminum or brass. The mini machines work on the same basis as its grown counterparts. Even though you will not be able to the type of work with a mini machine that you would with a large lathe machine, as in long runs, etc, you will still be able to create projects on the same basis. Carve, etch, taper, you name it, the CNC mini lathe can still do it.

 

The great thing about CNC technology is that with the software program you can recreate any project over and over. It could be years in between that same specific project and all you have to do is download the same software again and the project will turn out to the exact same measurements and specifications as the original.

 

Many people create their own versions of the mini lathe machine. Homemade DIY mini CNC machines can be created, but you must have some sort of knowledge about how the CNC technology works, computers, circuitry, the different axes that is used, etc. There is actually quite a bit of stuff that goes into a computer numeric controlled machine that incorporates robotic technology.

 

CNC mini lathes come in a variety of sizes, believe it or not. Some offer higher rpm rates. They usually operate on two or three of the axes and those are X, Y and sometimes X, Y, and Z. By knowing about the different axes and the type of movements that can be created using a combination of the axes, you will really be able to create some amazing projects.

 

Most of the time the program interface that is used with CNC mini lathes is very simple to operate and you can find the ones that even operate off of Windows. Different graphic programs can be used and then turned into a program that the machine will then duplicate. Just imagine all the different things that you can do with this sort of technology.

 

A variety of different manufacturers offer versions of the mini lathe machines and if you have any questions all you have to do is contact them. They can help you to even determine what size of the mini lathe machine would be perfect for you.

Advantages and Disadvantages of CNC Machining Vs Manual Lathes

Posted on by

While the Metal Spinning industry is ploughing its way through making hundreds and thousands of machine spun products, you have to wonder what the advantages are and disadvantages of CNC (Computer Numerical Control) machines compared to manually operated center Lathes?

 

CNC machines are very expensive to buy; however as the years move on the cost is decreasing due to the development of more efficient CNC models (and software). Manual lathes are cheaper to buy and require less setting up whereas CNC machines require you to either have somebody install and set it up or you can do this process yourself.

 

Size matters! If you are an SME (small to medium size enterprise) you may not have the space available for a CNC machine. Most models take up more than space then a manual lathe. CNC’s can contain and collect unwanted debris compared to manual lathes where the debris fall to the floor, making it a trip hazard and generally making the workshop look untidy.

 

CNC machines can be operated by one person. That one person can attend to more than one machine due to the machine producing all the work, with only a need to either change the tooling, replace a finished product with a new piece of material or to collect and dispose of material debris. Little training is needed for this one person to work the CNC machine. This is declining the need for skilled manual lathe workers, putting people out of work, and threatening the industry with less people being taught in the art of manual machinery type jobs.

 

CNC machining is reliably 99.99% accurate, and can produce products four times quicker than on a manual lathe. The other .1% is when the product dimensions can sometimes be off by up to 0.5mm, often this is due to the type of material, the temperature of the environment or the tooling being faulty; however this is a very rare occurrence. The machine is designed and programmed in such a manner that thousands of products with the same dimensions can be manufactured with complete accuracy and just with a single command. Even though the advantage to a CNC machine is that it can produce products with speed and accuracy, there are some jobs it can’t do, that a skilled worker can achieve on a manual lathe. But the downside to this is that human error can’t product a perfect product every time.

 

The CNC machine can be operated 24 hours a day, all year round, only stopping for maintenances. At the same time, updating the software can improve performance and speed. Depending on the type and size of job the CNC is required to do; renewing the tooling can be both cheap and expensive.

 

Prototypes are often required by the client before making the actual product. This could be to make sure the product has been designed correctly and can be made to the exact specifications. Finding a fault in the design early in the product life cycle will mean the design can be altered and will save time and money. The CNC machine does have the software that can simulate prototypes, therefore eliminating the need to use the CNC machine to make a physical prototype. This is another way to save money and time.

 

There may be more positives for the use of a CNC machine, but it would be wise if a SME wants to invest in a CNC machine, to always keep the manual lathe process within the company and not always rely on CNC machines. Although they allow for a much faster and accurate production line and eventually it will pay for itself, there is always the possibility that It could break down, so a backup of manual lathes can at least keep up with the constant demand of work should the need arise.

 

Shun Chuan is a professional lathes manufacturer who specialize in producing CNC lathe and manual lathe for more than 15 years. They insist to manufacture the efficiently and high-performance lathe machines for clients. Also, Shun Chuan dedicates in research and development to innovate lathes to meet the clients’ demands in top standard.
