 Life of the mold 

 Different purposes, using the correct hardness, high wear resistance, high toughness in order to avoid due to chipping or rupture, resulting in mold early failure of the material with high wear resistance, often with the problem of low toughness, so many examples display, along with high wear resistance and toughness, die life is the most important. ASP-23 tool steel using powder metallurgy manufacturing, combined with the best wear resistance and toughness.

 Mold manufacturing 

 Machining and heat treatment, grinding · heat treatment size of the stability of surface treatment of high alloy tool steel processing and heat treatment, usually higher than the low alloy tool steel is more difficult, so the manufacturing cost of the mold is also very high, while the ASP powder metallurgy manufacturing -23, the machining of manufacture than the traditional method of high-alloy tool steel Fortunately, the dimensional stability of the heat treatment is better, and easier to predict. More features due to its high hardness, high toughness and high temperature tempering, particularly suitable for surface treatment, such as PVD titanium. 
 Use 
 ASP-23 is particularly suitable in thin processing material under the materials and shape, or die failure is because of the mixed-abrasive wear and adhesive wear, or knowledge of abrasive wear, and surface plastic deformation of the risk the higher, for example: carbon steel or high carbon steel cutting punching hardened steel or cold-rolled steel strip contains a glass fiber plastic mold plastics molding machine parts such as: screw, barrel, nozzle, injection head, crush knife .
