Applications of 10Ni3MnCuAl Plastic Mold Steel
10Ni3MnCuAl is a precipitation-hardening pre-hardened plastic mold steel, widely used in the manufacturing of high-precision plastic molds requiring superior surface quality due to its excellent combination of properties.
1. Transparent Plastic Product Molds
Typical Products: Optical lenses, camera modules, cosmetic containers, medical device housings, etc.
Advantages:
The material offers exceptional mirror polishing performance (surface roughness Ra ≤ 0.05 μm), enabling high transparency and streak-free surface finishes that meet stringent requirements for precision optical products.
2. Automotive Component Molds
Typical Products: Headlamp covers, instrument panels, interior trim parts, sensor housings, etc.
Advantages:
Its high strength (hardness 37-43 HRC) and fatigue resistance allow it to withstand high injection pressures and frequent mold opening/closing cycles during the molding process.
Corrosion resistance (e.g., against sweat and grease) extends mold service life.
3. Electronic Device Housing Molds
Typical Products: Mobile phone frames, laptop casings, smart wearable devices, etc.
Advantages:
Uniform hardness distribution throughout the material (surface-to-core hardness difference ≤ 2 HRC) ensures dimensional stability of molded products and reduces deformation risks.
4. Precision Thread and Thin-Walled Molds
Typical Products: Threaded bottle caps, micro-gears, thin-walled packaging containers, etc.
Advantages:
High hardness and wear resistance minimize mold wear, while excellent electrical discharge machining (EDM) performance supports precise machining of complex cavities.
