The vacuum evacuation process is a crucial step in the carbon fiber industry, aimed at ensuring the quality and integrity of the final products. In this process, pre-impregnated carbon fiber fabric or materials are placed in a mold, and a vacuum is applied to remove air and gases from within the material. 

—— Ensure Sealing: Throughout the process, the seal of the vacuum bag is crucial. Any air leaks will affect the vacuum evacuation effectiveness.

—— Vacuum Level Control: The vacuum level directly affects the evacuation of gases and the density of the material, so precise control is necessary.
