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.

The wall thickness of the die-casting part is too thin, making it difficult to fill during die-casting and prone to poor filling. The wall thickness of die-casting parts is too thick and internal parts are prone to appear.

Wire cutting  uses electric spark discharge to cut metal, and CNC machining uses computer-controlled machine tools to perform precision machining. Both are commonly used in mold making.
