Our H13 mold manufacturing follows strict heat treatment protocols with vacuum oil quenching and triple tempering to achieve optimal hardness distribution and microstructure. Each H13 mold undergoes hardness mapping verification across the cavity surface before final polishing. We have extensive experience processing high-temperature engineering plastics for aerospace, medical, and industrial applications.
Q: When should I choose H13 over P20 or 718H?
A: Choose H13 when processing engineering plastics requiring mold temperatures above 120°C, such as PEEK (180°C), PPS (150°C), or PEI (160°C), where standard mold steels would soften and wear rapidly.
Q: Can H13 molds handle glass-filled materials?
A: Yes. H13 at 48-52 HRC provides excellent wear resistance against glass fiber and carbon fiber reinforced engineering plastics.
Q: What is the maximum mold temperature for H13?
A: H13 maintains its hardness and dimensional stability at mold temperatures up to 200°C continuous operation, making it suitable for the highest-temperature engineering thermoplastics.
Q: Do you perform heat treatment in-house?
A: We partner with certified heat treatment facilities using vacuum furnaces with oil quenching capability, with full hardness and microstructure reports provided for every mold.
