Non-Standard Mold Components with Böhler H13 Steel for Cosmetic Packaging and 0.005mm Accuracy
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.
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.
While our expertise lies in machining multi-cavity molds for cosmetic caps, medical syringes, and automotive components down to micron-level accuracy, every masterpiece begins with its raw material. We strategically source tool steel exclusively from global leaders like Uddeholm, Hitachi, and Bohler.
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.
Sourced directly from ASSAB® with mill test reports. Superior corrosion resistance and mirror finish capability, ideal for surgical instrument molds and transparent plastic components.
Premium-grade steel from leading European suppliers offering extreme wear resistance and precision maintenance under heavy-load cycles, perfect for high-volume production molds.
Why Our Materials Matter: 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.
5-axis CNC machines achieving tolerances of ±0.005mm, forming complex surfaces in single operations for precision and efficiency.
Precise electrode discharge technology for intricate structures like deep slots and narrow gaps, providing high accuracy while preserving tool life.
Ultra-smooth finishes with minimal surface roughness, perfect for optical components and high-precision molds.
Reliable precision and performance for wide range of turning operations, ensuring consistent quality and high productivity.
Mirror-like surface finishes (Ra ≤ 0.1μm) reducing demolding resistance and improving production efficiency.
Vacuum quenching and nitriding combination ensuring no oxidation or deformation while increasing surface hardness and wear resistance.
Our comprehensive quality inspection system ensures zero-defect deliveries through advanced measurement and testing equipment:
- CMM (Coordinate Measuring Machine): Zeiss CMM for full-dimension scanning to verify CAD drawing compliance
- Optical Projector: Quick and precise measurements of tiny holes and thread accuracy
- Hardness Testing: Rockwell and Vickers hardness testers to verify heat treatment effectiveness
- Cylindricity Instrument: Ensures perfect cylindrical shapes meeting highest standards
