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 across industries including daily-use packaging, cosmetics packaging, medical consumables and packaging, automotive, electronics, and automation.
Premium Tool Steel Materials from Global Leaders
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, 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.
Material Advantages: Raw materials purchased directly from BOHLER and ASSAB with original certifications. Full traceability at batch level ensures compliance with ISO 13485 and IATF 16949 standards. Optimized steel grades extend mold lifespan by 30-50% compared to generic alternatives.
Advanced Machining Techniques for Micron-Level Accuracy
- Roders CNC Machining: 5-axis CNC machines achieving tolerances of ±0.005mm for complex surface formation
- Makino EDM: Precise electrode discharge technology for intricate structures like deep slots and narrow gaps
- Sodick Wire EDM: Ultra-smooth finishes with minimal surface roughness for optical components
- Hardinge CNC Turning: Reliable precision and performance for diverse turning operations
- Grinding and Polishing: Mirror-like surface finishes (Ra ≤ 0.1μm) reducing demolding resistance
- Heat Treatment: Vacuum quenching and nitriding for enhanced material properties without oxidation or deformation
Rigorous Quality Control for Zero-Defect Deliveries
Our comprehensive inspection process ensures every component meets exact specifications:
CMM (Coordinate Measuring Machine): Zeiss CMM for full-dimension scanning against CAD drawings
Optical Projector: Precise measurements of tiny holes and thread accuracy
Hardness Testing: Rockwell and Vickers testers verify heat treatment effectiveness
Cylindricity Instrument: Ensures perfect cylindrical shapes meeting highest standards
