For these products, in addition to ensuring the size and appearance according to the drawing requirements, the customer's most important requirement is the product life, usually 20,000 shots/product. Therefore, the raw materials for these products are often high-hardness materials such as SKH51, DURO-F1, DURO-N1, SKD61, etc. These products, after rough processing, must undergo a heat treatment process to increase their wear resistance as well as product life.

   Therefore, in addition to control the quality of the internal production process, we must choose reputable raw material suppliers and heat treatment partners. In particular, some products require an additional stellite welding step to prevent wear, increase hardness and product life.
