Product quality:
We know that quality comes from details, so in every process of product manufacturing, we strictly require and control it.
1: From the selection of raw materials, we strictly choose 65CrMnTi. This grade has good hardenability and temperability physical characteristics. Because the material itself has the characteristics of high strength and high toughness, the products made of this material also have such characteristics.
2: Product manufacturing process: We have sophisticated machinery and equipment to ensure product accuracy.
3: Product inspection: We have advanced product production inspection equipment, and the products after production and processing have passed 100% inspection. The product will only leave the factory if it passes the inspection.
4: Product labeling: After inspection, it will be marked on the product according to the different load capacity and specifications of the product.
5: Product Precautions: For each product, there are instructions for use and precautions for product use.
