Metal bending is as old as the first time humans have discovered that metal can be used as a property to produce many things that are used daily. But since the metal is very hard, some bending companies need to adopt methods that can bend the metal to the required specifications. However, before technology has yet to reach different areas of operation in today\'s era, people usually use manual folding machines to complete their tasks. The Manual metal bending performed earlier used many of the same methods as those still used today. These industries may use them more precisely, or because some machines still cannot achieve the same effect as manual machines. The difference between bending technology and the old and present machines is mainly that modern machines are driven by electric, mechanical or hydraulic to facilitate the operator. Some modern metal winding machines used in today\'s industry are controlled by computers; This means that the entire task can be entered into it. This method is convenient when a large amount of metal needs to be bent on the same specifications. However, this does not help much when orders of different specifications are needed. Manual folding machine can also be found today; in fact many D. I. Y lovers keep such equipment at home. You can find a strange metal twister somewhere in their garage. This is a good investment. It can help host a lot sometimes. Many home pipes and fittings work by bending a tube or any other metal. It would be helpful if a simple but effective Manual metal winding machine was at home. Every time there is a small problem, there is no need to call a plumber or a pipe fitter. A manual winding machine for light work usually has a mold set. The metal is clipped to the clip and then bent to the mold, which forms the shape. Therefore, the shape is formed when the metal is pushed into the machine. In industry, however, there are many complex methods for bending metals. Some wells- For clarity, the known bending techniques are listed below. It is effective and efficient to use either of them: air bending, folding, winding, rotating bending, three point bending elastic bending and wiping.
