Custom Injection Mold Parts in Tool Steel (Böhler / ASSAB)
Dongguan SENLAN Mold Parts Co., Ltd., established in 2006, specializes in precision machining of custom mold components for precision packaging molds. With extensive industry experience and technical expertise, we deliver efficient and professional mold parts processing services to clients worldwide.
Core Business
We focus on 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 across 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.
Material Specifications
- 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
- Stavax® ESR (420 Stainless Tool Steel): Sourced from ASSAB® with mill test reports, offering superior corrosion resistance and mirror finish capability for surgical instrument molds and transparent plastic components
- M340 High-Hardness Steel: Premium-grade steel from European suppliers providing extreme wear resistance for high-volume production molds, thread cores, and ejector pins
All materials include full traceability with original certifications from BOHLER and ASSAB, ensuring compliance with medical (ISO 13485) and automotive (IATF 16949) standards. Our 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 surface forming
- Makino EDM: Electrical discharge machining for intricate structures, deep slots, and narrow gaps
- Sodick Wire EDM: Ultra-smooth finishes with minimal surface roughness for optical components
- Hardinge CNC Turning: Precision turning operations ensuring consistent quality and productivity
- Grinding and Polishing: Mirror-like surface finishes (Ra ≤ 0.1μm) reducing demolding resistance
- Heat Treatment: Vacuum quenching and nitriding for enhanced hardness and wear resistance
Rigorous Quality Control
Our comprehensive inspection process ensures zero-defect deliveries through advanced measurement technology:
- CMM (Coordinate Measuring Machine): Zeiss CMM for full-dimension scanning against CAD specifications
- Optical Projector: Precise measurements of tiny holes and thread accuracy
- Hardness Testing: Rockwell and Vickers testers verifying heat treatment effectiveness
- Cylindricity Instrument: Ensuring perfect cylindrical shapes to highest standards
