Production process control

For the process, whether it can produce qualified products or high-quality products in a long-term and stable manner must meet two basic conditions: there is sufficient process capability, and the process remains stable and controlled. GRH’s control of the production process is mainly reflected in the control of the production operation plan, the control of raw materials, purchased parts, external parts, process components, the control of the manufacturing environment, the control of equipment, tooling and the control of key processes . GRH took the lead in introducing the concepts of 5S site management and TPM comprehensive production management in the industry.
