What is metal stamping?

Metal stamping is a metal cold processing method, also known as cold stamping or sheet metal stamping, with the power of stamping equipment, the metal sheet is directly formed in the mold, stamping parts are widely used in automotive parts manufacturing and household appliances manufacturing.

Suitable material: Suitable for most metal plates, especially for: carbon plate, stainless steel plate, aluminum plate, magnesium plate, copper plate and zinc plate

Metal stamping process

Metal stamping process

The metal stamping process consists of the following steps:

cutting

First, the metal raw material is placed on the work table of the cutting machine. Cutters use cutting tools to cut sheet metal to the desired size and shape. This process involves precise measurement and cutting techniques to ensure that the dimensions of the raw material meet the requirements. At the same time, in order to improve production efficiency and accuracy, some modern cutting machines are also equipped with automatic feeding systems and computer control systems.

blanking

After the cutting is completed, the cut sheet metal is sent to the blanking station of the punching machine. Blanking refers to the process of placing the sheet metal in the lower die and pressing the sheet metal into shape through the pressure of the punching machine. During blanking, the upper die is closed with the lower die, fixing the sheet metal in the desired position and applying enough pressure to shape it.

molding

After blanking is completed, adjust the mold to the forming station. Molding refers to the process of extruding sheet metal into parts of various shapes through a mold. During the molding process, the upper and lower die are closed, the metal sheet is fixed in the mold cavity, and enough pressure is applied to make it form. The design and manufacturing accuracy of the mold play a crucial role in the molding effect. In order to ensure the quality of molding, it is necessary to select the appropriate mold material and processing technology, and carry out accurate measurement and debugging.

trimming

After forming, trimming treatment is required. Trimming refers to the removal of excess burrs and flash edges of metal stamping parts to improve their appearance quality and assembly performance. Edging can be done manually or mechanically. When mechanical trimming is used, a rotary or swinging trimming machine is usually used to cut off the excess part through a cutter. The effect of trimming depends on the choice of tool, cutting parameters and the skill level of the operator.

inspect

After each processing stage, inspection should be carried out to ensure that the quality and dimensions meet the requirements. Inspection usually includes visual inspection, dimensional measurement, and more detailed testing using inspection tools. If non-conforming products are found, they need to be reworked or scrapped. Inspection is an important link to ensure the quality of the final product.

The metal stamping process usually works with the help of a slider or punch, a press, and a stamping die or stamping tool. The process itself can be broken down into a few simple steps as follows:

Insert sheet metal: The manufacturer inserts the metal plate into the punch, which is a fixed workbench.

Complete shaping operation: A mold is a tool consisting of a custom-designed cavity to form a metal part from an inserted metal plate. The upper part of the die is connected to the press slider, which maintains the movement in and out of the press, while the lower part is connected to the press. Another mold component, called a punch, completes the molding operation by pushing a metal plate through the mold.

Secondary processing: The metal stamping parts after forming usually go through one or more secondary processing, such as flanging, deep drawing, bending, etc., to get the final product.
