Products Quality Control
Quality control involves the inspection and control of incoming materials, production processes, and finished products. The quality control process includes:
- Firstly, incoming raw materials undergo random sampling and analysis using a metallographic microscope to ensure the chemical composition meets production requirements.
- During the production process, QC staff conduct timely sampling to ensure products are defect-free, coordinating and addressing any quality issues that may arise.
- The final step involves using a magnetic particle flaw detector on metal parts to detect hidden cracks or defects.
- All finished metal parts are proportionally sampled and sent to the laboratory for mechanical performance tests, size measurements, and 100% manual surface quality inspection.
