Precision Multi-Cavity Bottle Cap Mold Parts with ±0.005mm Tolerance Control and Premium Tool 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.

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.

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.

• Roders CNC Machining: 5-axis CNC machines achieving tolerances of ±0.005mm for complex surfaces in single operations
• 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 turning operations with consistent quality
• 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

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 specifications
• Optical Projector: Quick and 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

Quality Inspection Process: Material incoming (100%), Rough Finished (100%), Heat treatment (random), Face grinding (100%), Center-less cylindrical grinding (100%), OD/ID grinding (100%), EDM (100%), Wire-Cutting (100%), Packing (final 100% inspection)

Our precision mold parts power diverse industries including daily-use packaging, cosmetics packaging, medical consumables and packaging, automotive components, electronics, and automation systems.
