Precision Multi-Cavity Bottle Cap Mold Parts with ±0.005mm Tolerance Control
Dongguan SENLAN Mold Parts Co., Ltd., established in 2006, specializes in precision machining of mold components with a focus on non-standard customization for precision packaging molds. With extensive industry experience and technical expertise, we deliver efficient and professional mold parts processing services to global clients.
Core Business Expertise
We specialize in 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 across multiple 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 quality and performance.
H13 Hot-Work Steel: Bohler Uddeholm® material with exceptional thermal fatigue resistance, ideal for high-temperature injection molding applications including automotive molds and complex cavity inserts. Full batch traceability provided.
Stavax® ESR (420 Stainless Tool Steel): Sourced from ASSAB® with mill test reports, offering superior corrosion resistance and mirror finish capability for surgical instrument molds and transparent plastic components.
M340 High-Hardness Steel: Premium-grade steel from European suppliers providing extreme wear resistance and precision maintenance under heavy-load cycles, perfect for high-volume production molds, thread cores, and ejector pins.
Material Advantages: Raw materials purchased directly from BOHLER and ASSAB with original certifications. Full batch-level traceability ensures compliance with medical (ISO 13485) and automotive (IATF 16949) standards. Optimized steel grades extend mold lifespan by 30-50% compared to generic alternatives.
Advanced Manufacturing Process
- Roders CNC Machining: 5-axis CNC machines achieving ±0.005mm tolerances for complex surface formation in single operations
- Makino EDM: Precise electrode discharge technology for intricate structures, deep slots, and narrow gaps with non-contact processing
- Sodick Wire EDM: Ultra-smooth finishes with minimal surface roughness for optical components and high-precision molds
- Hardinge CNC Turning: Reliable precision turning operations ensuring consistent quality and high productivity
- Grinding and Polishing: Mirror-like surface finishes (Ra ≤ 0.1μm) reducing demolding resistance and improving production efficiency
- Heat Treatment: Vacuum quenching and nitriding combination preventing oxidation and deformation while increasing surface hardness and wear resistance
Rigorous Quality Control
Comprehensive inspection protocols ensure 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 verifying heat treatment effectiveness
- Cylindricity Instrument: Ensuring perfect cylindrical shapes meeting highest standards
Complete Production Inspection Process:
Material incoming: 100% inspection | Rough Finished: 100% inspection | Heat treatment: random inspection | Face grinding: 100% inspection | Center-less cylindrical grinding: 100% inspection | OD/ID grinding: 100% inspection | EDM: 100% inspection | Wire-Cutting: 100% inspection | Packing: Final 100% inspection before shipment
