High-Precision CNC Machined Mold Inserts with ±0.005mm Tolerance
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 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 and inserts. Our products serve precision packaging molds for industries including daily-use packaging, cosmetics packaging, medical consumables and packaging, automotive, electronics, and automation.
Premium Tool Steel Materials
We source tool steel exclusively from global leaders including Uddeholm, Hitachi, and Bohler to ensure superior material quality and performance.
- H13 Hot-Work Steel: Bohler Uddeholm® material with exceptional thermal fatigue resistance, ideal for high-temperature injection molding applications with full traceability
- Stavax® ESR (420 Stainless Tool Steel): Sourced from ASSAB® with mill test reports, offering superior corrosion resistance and mirror finish capability for medical and optical-grade molds
- M340 High-Hardness Steel: Premium-grade steel from European suppliers providing extreme wear resistance for high-volume production molds and thread cores
Our raw materials are purchased directly from BOHLER and ASSAB with original certifications. We provide full traceability at batch level, ensuring compliance with medical and automotive standards including ISO 13485 and IATF 16949. Optimized steel grades extend mold lifespan by 30-50% compared to generic alternatives.
