Terminology of metal stamping and metal stamping parts

Dongguan Precision Electronic Technology Co., Ltd. is a professional manufacturer of metal stamping parts in Dongguan. Provide non-standard customized processing and production of precision metal stamping parts. What is metal stamping? Metal stamping is a process that uses punches and molds to deform or break stainless steel, iron, aluminum, copper and other plates and other materials to have a certain shape and size. Metal stamping is sometimes called sheet forming, but there is a slight difference. The so-called sheet forming refers to the use of sheet materials, thin-walled tubes, thin profiles, etc. as raw materials. Metal stamping parts are products after a series of processes, with different terms in different processes. The common terms of metal stamping parts are: deep drawing: a stamping process in which straight wool or process parts are turned into hollow parts, or the hollow parts are further changed in shape and size. During deep drawing, the hollow part is mainly formed by the material located outside the bottom of the convex die flowing into the concave die. Trimming: A stamping process that uses a metal stamping die to trim the edge of the forming process to make it have a certain diameter, a certain height or a certain shape. Punching: A punching process that separates the waste from the material or process part along a closed contour to obtain the required hole in the material or workpiece. Flanging: A stamping process in which the short sides are turned sideways along the contour curve. Hole turning: A stamping process in which the material is turned into a side flange along the inner hole. Blanking: A stamping process that separates materials along a closed contour. The separated materials become workpieces or process parts, most of which are flat. Shaping: A stamping process that depends on the flow of materials and changes the shape and size of the process parts in a small amount to ensure the accuracy of the workpiece.
