Shrinking and Stretching Methods Used in Sheet Metal Manufacturing in Washington

Tucking metal is a process that refers to one of the oldest methods used for shrinking metal. This method requires operators to bunch metal together. The metal will often be folded over the edges of a tucking fork. Shrinking may also be performed with the use of a lever-operated tool equipped with textured jaws. The jaws grasp the metal at the top and the bottom and then force the metal together in a tight manner. While the process is slower than tucking, it is more precise. One of the benefits of using a shrinker is that you can work specific areas of the metal. In addition, a shrinker results in very little marring of the metal.

Heat shrinking is another process used in sheet metal manufacturing in Washington. Operators must have a tremendous amount of practice in order to successfully use this method. This method is based on heating a section of overstretched metal with a torch. As the area begins to cool, it will shrink. How the area is smoothed out will be determined by the amount or type of stretched metal. This method may also be performed with the use of shrinking discs that can be attached to an angle grinder in order to create friction and heat. This method is often preferred over a torch for the accuracy it provides.

Along with shrinking, sheet metal manufacturing in Washington may also involve the stretching of metal. The most basic method for stretching metal involves the use of a hammer and dolly. A mechanically operated tool known as a stretcher may also be used in order to pull metal apart in a slow and deliberate manner. In some instances, sheet metal manufacturing in Washington may use an English wheel for stretching metal. A flat-faced, large upper wheel is used with a lower anvil to roll the metal back and forth, thus stretching the metal.
