ASSAB Mold Steel Custom Non-Standard Cores with 0.005mm Precision for Packaging Molds
Dongguan SENLAN Mold Parts Co., Ltd., established in 2006, specializes in precision machining of mold components with expertise in non-standard customization for precision packaging molds. With extensive industry experience, we deliver efficient and professional mold parts processing services to global clients.
Core Business Expertise
We specialize in precision machining of multi-cavity mold components including plastic mold cavities, core pins, inserts, movable core assemblies, and automotive die-casting mold cores. Our products serve precision packaging molds for industries including daily-use packaging, cosmetics packaging, medical consumables, automotive, electronics, and automation.
Premium Tool Steel Materials
We source tool steel exclusively from global leaders including Uddeholm, Hitachi, and Bohler to ensure superior quality and performance.
H13 Hot-Work Steel: Bohler Uddeholm® material with exceptional thermal fatigue resistance, ideal for high-temperature injection molding applications including automotive molds and complex cavity inserts. Full batch traceability provided.
Stavax® ESR (420 Stainless Tool Steel): Sourced from ASSAB® with mill test reports. Excellent for surgical instrument molds and transparent plastic components with superior corrosion resistance and mirror finish capability.
M340 High-Hardness Steel: Premium-grade steel from European suppliers offering extreme wear resistance, maintaining precision under heavy-load cycles for high-volume production molds, thread cores, and ejector pins.
Material Advantages: Raw materials purchased directly from BOHLER and ASSAB with original certifications. Full traceability at batch level ensures compliance with medical (ISO 13485) and automotive (IATF 16949) standards. Optimized steel grades extend mold lifespan by 30-50% compared to generic alternatives.
Advanced Manufacturing Process
- Roders CNC Machining: 5-axis CNC machines achieving ±0.005mm tolerances for complex surfaces in single operations
- Makino EDM: Precise electrode discharge technology for intricate structures, deep slots, and narrow gaps
- Sodick Wire EDM: Ultra-smooth finishes with minimal surface roughness for optical components
- Hardinge CNC Turning: Reliable precision turning operations with consistent quality
- Grinding and Polishing: Mirror-like surface finishes (Ra ≤ 0.1μm) reducing demolding resistance
