Roughly speaking, it can be divided into punching that cuts objects from materials, bending materials along molds, making thin-walled parts such as cylindrical and stepped shapes invisible, and spinning and stamping objects that rotate materials together along molds to press out concentric circular parts, which are widely used in various fields. Household products, computer cases in the workplace, parts in the automotive industry, and casings of some machine tools are all used in daily life. The forming principle is a processing method that applies pressure and deformation to materials through punching machines and molds. The punching mold is quite important, in addition to determining the size of the product. In addition to appearance, there needs to be sufficient structural strength to withstand tens of thousands of impacts, which heavily relies on experience in mold design. If the design is improper and affects production, it can be serious. In fact, charging is a comprehensive application function. So in the first product or software, techniques such as punching, bending, stealth, and spinning are used. It is a common phenomenon in stamping products, and the requirements for processing quantity are also not strict. When there is a large amount of manual feeding in two hours, automated production can also be achieved with great processing flexibility, which is also a commonly used effect in manufacturing.
