1. Heat treatment
As we all know, heat treatment is very critical in the screw production process. In order to ensure the quality of products, Jiangning has purchased professional heat treatment equipment to produce, so as to control this key process by itself.
2. The accuracy of the product
Finishing is carried out after the heat treatment, which can eliminate the deformation of the parts in the heat treatment, so that the accuracy is higher, so that seamless connection can be achieved.
