Production quality control to rail spike
We pay much attention to the quality control and management to the dog spike production, strictly in accordance with ISO9001-2008 QS. In addition, our rail spikes are approved by China’s Ministry of Railways. What’s more, our production base is equipped with full sets of inspection facilities to ensure the spike quality in order to meet our clients’ requirements.
For the quality control from supplier to finished products, we operate following standard procedures:
- Test the raw materials on production batch No, chemical compositions, physical properties, etc.
- The quality controller selects samples from time to time for inspection and quality report issuance.
- Depending on different requirements, we work out chemical or physical inspection accordingly. If the result disobey our requirement, we refuse the materials, till satisfied finally.
- For the semi-finished products or outsource parts, we often organize quality control coordination meetings on technical assistance and guidance, aiming to ship qualified products to our customers.
