Precision Machining of Mold Components for Daily Packaging and Cosmetics Packaging
Our high-precision machined mold components are engineered for superior performance in daily-use and cosmetics packaging production. Utilizing advanced CNC machining and EDM technologies, we ensure micron-level accuracy, exceptional durability, and flawless surface finishes.
These molds are tailored for intricate designs, consistent quality, and high-volume efficiency, catering to caps, jars, bottles, and compacts. Made from premium materials like hardened steel and carbide, they resist wear and corrosion, extending service life. Ideal for PET, PP, glass, and metal packaging, our solutions enhance production speed while minimizing defects.
About Our Company
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.
Core Business
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.
Premium Materials from Global Leaders
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.
H13 Hot-Work Steel
Bohler Uddeholm® material with exceptional thermal fatigue resistance, perfect for high-temperature injection molding applications. Full traceability with every batch.
Stavax® ESR (420 Stainless)
Sourced from ASSAB® with mill test reports. Superior corrosion resistance and mirror finish capability for medical and optical-grade molds.
M340 High-Hardness Steel
Premium-grade steel from European suppliers offering extreme wear resistance for high-volume production molds and thread cores.
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.
Advanced Manufacturing Process
Our comprehensive manufacturing process ensures micron-level accuracy and superior quality in every component we produce.
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
Heat Treatment: Vacuum quenching and nitriding for enhanced material properties without oxidation
Rigorous Quality Control
Our comprehensive quality inspection process ensures zero-defect deliveries through advanced measurement technologies and 100% inspection at critical production stages.
