Xiamen Creator Technology Co., Ltd. manufactures injection molds using premium S136 (420 ESR) stainless mold steel, ideal for high-polish optical and medical parts requiring corrosion resistance, excellent polishability, and long-term dimensional stability. S136 is the preferred choice for transparent PMMA and PC optical components and medical device molds.
| Mold Steel | S136 (420 ESR Stainless) |
| Hardness | 48-52 HRC |
| Polishability | SPI A1 Mirror (Ra ≤ 0.025μm) |
| Corrosion Resistance | Excellent (vs PVC, FR Resins) |
| Mold Life | 500,000 - 1,000,000 shots |
| Application | Optical Lenses, Medical Devices, Transparent Parts |
| Heat Treatment | Vacuum + Triple Tempering |
| Tolerance | ±0.01mm |
Since 2007, our mold steel selection is driven by application requirements. For optical and medical molds, we exclusively use S136 ESR stainless steel sourced from certified mills (Assab, Bohler, Daido). Each steel batch is verified with spectrometer analysis before machining. Our vacuum heat treatment with triple tempering ensures optimal hardness distribution and stress relief for long-term dimensional stability.
Q: Why use S136 stainless steel for molds?
A: S136 offers excellent corrosion resistance against aggressive resins (PVC, FR grades), superior polishability for optical parts, and consistent hardness through the entire cavity depth.
Q: What is the difference between S136 and NAK80?
A: S136 is stainless with superior corrosion resistance, ideal for medical and optical parts. NAK80 is pre-hardened with excellent polishability for general high-gloss applications without corrosion concerns.
Q: How do you verify steel quality?
A: We use spectrometer analysis to verify chemical composition of every steel batch, and hardness testing to confirm heat treatment results before machining.
Q: When should I choose S136 over P20 or 718H?
A: Choose S136 when producing transparent optical parts, medical components, or parts using corrosive resins (PVC, flame-retardant grades) where surface quality and corrosion resistance are critical.
