Sheet metal is a general term for the process of cutting, punching, folding, welding and other cold processing of metal sheets (usually less than 6mm thick) to make the required prototypes or parts.

Also known as injection molding, its principle is to add granular or powdery raw materials into the hopper of an injection machine. 

What makes CNC machine tools so "obedient" and "accurate" relies on the support of a series of key technologies:

The core of the energy storage battery PACK package die-casting process is to use high pressure to inject molten aluminum alloy into a precision mold to integrate key structures such as the box and liquid-cooling runner into one-time integration. 

Injection molding process setting should consider 7 factors including shrinkage, fluidity, crystallinity, heat-sensitive plastics and easily hydrolyzed plastics,

Have you also encountered this situation: the drawings are fine, the mold is opened normally and the process is in accordance with the process,

After CNC machining is completed, parts usually require post-processing to improve their appearance, performance and durability. 

Many injection molding defects, such as bubbles, silver streaks or insufficient strength, often result from improper handling of moisture in the material.
