CNC-Machined Mold Cores with ±0.005mm Tolerance in STAVAX/1.2083/M340 Materials for Injection Molding Components

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.

• Roders CNC Machining: 5-axis CNC machines achieving tolerances as tight as ±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 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

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