Common Mold Materials for Different Production Requirements
Mold steel is selected according to plastic material, annual production volume, required surface finish, corrosion resistance, dimensional stability and expected mold life.
| Mold Steel | Hardness | Typical Applications | Mold Life | Recommendation |
|---|---|---|---|---|
| P20 | 28–34 HRC | General-purpose injection molds, household products, automotive interior parts and medium-volume production. | 300,000–500,000 shots | Recommended for cost-effective standard production molds. |
| 718H | 33–38 HRC | Automotive components, appliance housings, medium-to-large molds and applications requiring improved polishability. | 500,000–800,000 shots | Recommended for durable molds with stable machining performance. |
| NAK80 | 37–43 HRC | High-gloss plastic parts, optical housings, consumer electronics and molds requiring mirror polishing. | 500,000–800,000 shots | Recommended for excellent surface finish and dimensional stability. |
| S136 | 48–52 HRC | Transparent plastic parts, medical-related housings, corrosive resins and high-polish precision applications. | 800,000–1,000,000+ shots | Recommended for corrosion resistance, cleanliness and long mold life. |
| H13 | 48–52 HRC | High-temperature tooling, die casting molds, hot runner components and wear-resistant mold inserts. | 800,000–1,000,000+ shots | Recommended for high heat, impact resistance and demanding production. |
