Punching

Metal stamping is a cold metal processing method, also known as cold stamping or sheet metal stamping. 

Using the power of a stamping machine, metal sheets are directly forced into shape within a mold. 

Stamped parts are widely used in automotive parts and household appliances.

🔧Applicable Materials: Suitable for most metal sheets, 

especially carbon steel, stainless steel, aluminum, magnesium, copper, and zinc.

⚙️Process:

1. The metal sheet is secured to the mold table.

2. The upper punch descends vertically, forcing the metal sheet into shape within the mold.

3. The punch rises, and the part is removed for trimming and polishing. The entire process takes approximately 1 second to 1 minute.

🔖One immediate benefit of stamping is cost savings. 

It eliminates the need for nano-injection molding and can be directly anodized after polishing, 

allowing for rapid ramp-up of mass production. However, this technology has the disadvantage that

 the upper and lower ends of the body must be joined by plastic.

 Complex internal structures cannot be created, making it suitable only for back covers.
