Mold design and manufacturing are closely related to plastic processing. The success or failure of plastic processing largely depends on the effectiveness of mold design and the quality of mold manufacturing, and plastic mold design is based on the correct design of plastic products.

The design of air extraction holes for vacuum forming is the key to mold design. The air extraction holes should be located at the last place where the sheet is attached to the mold,
