Quality Control

Raw material quality control

Our company has signed a long-term strategic cooperation agreement with the raw materials foundry. When the raw materials arrive at our factory, our company will use the PMI to evaluate the raw materials, and will measure the size and wall thickness of them. When the raw materials are qualified, they will be stored in the warehouse; if not, they must be returned to the foundry.
