High-Precision Custom Mold Inserts in H13 / 1.2344 / Dievar Steel
Dongguan SENLAN Mold Parts Co., Ltd. was established in 2006 and specializes in precision machining of mold components, particularly for non-standard customization in precision packaging molds. With years of industry experience and technical expertise, we provide efficient and professional mold parts processing services to global clients.
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 and inserts. Our products are primarily used in precision packaging molds for industries such as daily-use packaging, cosmetics packaging, medical consumables and packaging, as well as automotive, electronics, and automation.
Premium Tool Steel Materials
We strategically source tool steel exclusively from global leaders like Uddeholm, Hitachi, and Bohler to ensure superior quality and performance.
H13 Hot-Work Steel
Bohler Uddeholm® material with exceptional thermal fatigue resistance, perfect for high-temperature injection molding applications like automotive molds and complex cavity inserts. Full traceability with every batch.
Stavax® ESR (420 Stainless Tool Steel)
Sourced directly from ASSAB® with mill test reports. Superior corrosion resistance and mirror finish capability, ideal for surgical instrument molds and transparent plastic components.
M340 High-Hardness Steel
Premium-grade steel from leading European suppliers offering extreme wear resistance and precision maintenance under heavy-load cycles, perfect for high-volume production molds and thread cores.
Material Quality Assurance
Our raw materials are purchased directly from BOHLER and ASSAB with original certifications. We provide full traceability at the batch level, ensuring compliance with medical and automotive standards like ISO 13485 and IATF 16949. By using optimized steel grades, we extend mold lifespan by 30-50% compared to generic alternatives.
Advanced Manufacturing Process
- 5-Axis CNC Machining: Achieving tolerances as tight as ±0.005mm for complex surfaces in single operations
- Makino EDM: Precise electrode discharge technology for intricate structures and hard materials
- 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) to reduce 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 to verify heat treatment effectiveness
- Cylindricity Instrument: Ensures perfect cylindrical shapes meeting highest standards
