quality assurance
From raw materials to production to finished products, every step is strictly tested to ensure the quality and reliability of the products.
1. Material inspection
- When purchasing raw materials, we will require steel suppliers to provide steel quality certificates and steel tables.
- Carry out sampling tests on materials.
- Only qualified materials are allowed to be put into the warehouse, and then cold rolled and cut to achieve the ideal state of manufacturing the chain.
2. Inspection of parts
- The mold development center has inspected all molds before use.
- The operator checks the chain parts from time to time during the production process.
- The quality supervisor continuously inspects the workshop parts.
- The operator performs anti-rust treatment on all parts.
- The person in charge of quality inspects the mold every hour to ensure the accuracy of the mold.
3. Heat treatment
- Advanced heat treatment equipment ensures the high quality and stable characteristics of all chain parts. And all necessary data during the heat treatment is processed and recorded by the computer.
- The quality management personnel carefully test the hardness and carbon layer of the heat-treated chain parts, and record the results for submission to the quality control center in the future.
- Shot peening is a necessary procedure for GD chain. To a large extent, the fatigue strength and life of the chain are improved.
- All parts have undergone anti-rust treatment again.
4. Inspection during the production process
- Each assembly line is equipped with a part tester, which solves the problem of shortage of chain parts.
- The operator controls the width between the inner panels during assembly.
- Running-in.
- Short circuit test of parts.
- Surface and flexibility test.
5. Finished product inspection
- Tensile test
- Determination of chain length
- Fatigue fracture test
- Wear test
