Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of mold steel, it is recommended to prioritize the confirmation of key technical parameters such as hardness, wear resistance, and thermal stability based on specific processing scenarios (such as injection molds, die-casting molds, or stamping molds) to avoid performance redundancy or insufficiency.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers can usually provide more stable material batches and process consistency.
  • In high-precision mold manufacturing in the automotive or electronics industry, special attention should be paid to the purity and isotropic properties of mold steel, as such applications have a low tolerance for internal defects in the material.
  • For long-term cooperative suppliers, it is recommended to conduct a comprehensive evaluation based on their historical delivery cycles and industry reputation. The stability of mold steel supply directly affects the continuity of the production line.

Knowledge Base

Q

Plastic mold steel is mainly divided into two types based on its service life: pre hardened mold steel and quenched steel. Pre hardened mold steel generally has a hardness between HB340-380, and pre hardened steel is more common, such as P20/more well-known P20, such as 718MH/PX4/1.2738/XPM.

Q

P20 mold steel is a high-quality pre hardened plastic mold steel widely used in the mold manufacturing industry. It is known for its excellent machinability, wear resistance, and toughness. The hardness is within the range of 28-34HRC, suitable for mechanical processing, cutting, and grinding. It is easy to polish and suitable for manufacturing plastic molds with high smoothness. And it has good toughness and wear resistance, able to withstand high pressure and wear
