5. Heat treatment 
As we all know, 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.
