Non-Standard Steel Precision Mold Parts with ±0.005mm Tolerance and SKD61 Die Steel in Custom Sizes

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.

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
• Stavax® ESR (420 Stainless Tool Steel): Sourced from ASSAB® with mill test reports, ideal for surgical instrument molds and transparent plastic components
• M340 High-Hardness Steel: Premium-grade steel from European suppliers offering extreme wear resistance for high-volume production molds

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.

• Roders CNC Machining: 5-axis CNC machines achieving tolerances of ±0.005mm for complex surfaces
• 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 various turning operations
• Grinding and Polishing: Mirror-like surface finishes (Ra ≤ 0.1μm) to reduce demolding resistance
• Heat Treatment: Vacuum quenching and nitriding to enhance material properties and extend lifespan

Our comprehensive quality inspection process ensures zero-defect deliveries through advanced measurement technology:

• CMM (Coordinate Measuring Machine): Zeiss CMM for full-dimension scanning against CAD drawings
• Optical Projector: Quick and precise measurements of tiny holes and thread accuracy
• Hardness Testing: Rockwell and Vickers hardness testers for heat treatment verification
• Cylindricity Instrument: Ensures perfect cylindrical shapes meeting highest standards

Quality Inspection Process: 100% inspection at material incoming, rough finished, face grinding, center-less cylindrical grinding, OD/ID grinding, EDM, wire-cutting, and final packing stages with random inspection during heat treatment.

Our precision mold parts serve diverse industries including precision packaging, cosmetics, medical consumables, automotive, electronics, and automation sectors.
