Things to Look For When Selecting a Coil Straightener
The best coil straightener for your needs depends on the application, the type of work to be done and on the quality of the coil to be used. The coil straightener is usually the core of all the coil processing lines: it compensates for any deformation of the strip or sheet metal due to the process used. The ideal coil straightener would define the perfect parameters that would ensure the best possible performance. Unfortunately, it is hard to estimate the ideal parameters since this depends on a number of factors. However, as with any other product or service, you should try to get as accurate information as possible.
For example, the ideal coil straightener will have a minimum slippage of less than 1%. In addition to this, it must also have a minimum feed rate that is fast enough to feed the material through the machine without having to stop the process midway. On the other hand, a two-in-one uncover will have a lower feed rate, which will reduce slippage. A two-in-one uncoiler also ensures that the heat is evenly distributed and does not leave any part of the strip or sheet cold.
The main difference between a two-in-one coil straightener and a standard one is that the two-in-one has a larger feed rate than the standard one; and it has a larger and therefore larger roll adjustment. The large roll adjustment is necessary because the larger feed rate is needed to handle the thicker and heavier wire. If the wire is too thick or heavy, the two-in-one will not be able to complete the entire process, as its smaller roll adjustment will not allow it. The two-in-one also has an automatic shut off facility, which means you do not have to manually switch it off.
When selecting a coil straightener, you should check that it has a full width dual action design. It should have both a center core and ring core spring. A full width dual action spring enables it to work more precisely as compared to a standard spring with a one-piece ring core. The center core is used to get the material through the rollers smoothly and firmly. The ring core helps to support the rollers while they are in operation, and is essential to give you smooth and consistent results. It should also have preload protection to prevent sagging.
A coil straightener should be made using materials that are of high quality. It is a known fact that metals come at a higher price, but when it comes to applications and performance, they are actually worth it. The best metals to use are those that have the best resistance to corrosion, such as stainless steel, titanium, and copper. These materials are so strong and resilient because they are more malleable than the other materials. They can withstand a greater force as well as retain their shape without being destroyed easily.
Another factor that you have to consider is variable speed performance. It is imperative that you choose a coil straightener that has variable speed capabilities for better smoothing of fabric, and even heat control. Some of the variable speed units can work at an amazing 180 revolutions per minute. There are even some electric models that have twin or multiple speed settings so that you can choose the right one for the application needs that you have.
