Detailed Explanation Of Metal Stamping Process And Application

1. Overview of stamping process
Stamping is the use of molds and presses (punch presses) to apply pressure to metal sheets, causing them to separate or undergo plastic deformation, in order to obtain parts of the desired shape and size. It is mainly divided into two categories:
Separation process (such as punching, dropping): The material breaks and separates.
Forming process (such as bending, stretching, and flanging): The material undergoes plastic deformation without breaking.
2. Common materials
Low carbon steel: Low cost, easy to form, used for structural components.
Stainless steel: corrosion-resistant, used for household appliances and medical devices.
Aluminum alloy: Lightweight, used in automobiles and aerospace.
Copper and copper alloys: Good conductivity, used for electronic connectors.
Galvanized sheet: rust proof, used for outdoor parts.
3. Key points of quality control
Dimensional accuracy: depends on mold accuracy and machine stability.
Surface defects: Avoid scratches, indentations, and burrs (deburring treatment is required).
Material thickness: The thinning rate of the stretched parts should be controlled to prevent cracking.
Strength testing: Key components need to undergo tensile, hardness, and other tests.
4. Typical application areas
Automotive industry: body panels, chassis components, seat belt buckles, fuel tanks.
Electronic appliances: phone shields, heat sinks, connectors.
Home appliances: refrigerator door panels, washing machine casings, microwave oven brackets.
Industrial equipment: motor housing, gears, spring plates.
