3. Process of making
4. Raw material guarantee
The company has been cooperating with domestic and
foreign first-line brand material suppliers for a long time, and
has a strict quality control and performs regular audits and
inspection of the factory (elemental analysis, metallographic
analysis, ultrasonic flaw detection, etc.) to ensure a 100%
qualified status.
5. Heat treatment
Heat treatment is very important in the screw production process. In order to ensure the quality of products, Joiner has purchased professional heat treatment equipment to produce, so that we can control the construction process by ourselves. In China, we are the only company that does heat treatment by ourselves, and the heat treatment of screw components made by Nanjing factory is processed by outsiders, so the quality of products can not be completely guarantee.
