Precision Mold Parts - Core Pin Accuracy 0.003 mm for Medical Industry
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 Focus
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: We use Bohler Uddeholm® material with exceptional thermal fatigue resistance, perfect for high-temperature injection molding applications like automotive molds and complex cavity inserts. Every batch comes with full traceability.
Stavax® ESR (420 Stainless Tool Steel): Sourced directly from ASSAB® with mill test reports. Ideal for surgical instrument molds and transparent plastic components due to superior corrosion resistance and mirror finish capability.
M340 High-Hardness Steel: Premium-grade steel from leading European suppliers offering extreme wear resistance and precision maintenance under heavy-load cycles, perfect for high-volume production molds, thread cores, and ejector pins.
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
- Roders CNC Machining: 5-axis CNC machines achieving tolerances as tight as ±0.005mm, forming complex surfaces in one operation
- Makino EDM (Electrical Discharge Machining): Precise electrode discharge technology for intricate structures like deep slots and narrow gaps
- Sodick Wire EDM (W/EDM): Ultra-smooth finishes perfect for optical components and high-precision molds
- Hardinge CNC Turning: Reliable precision and performance for a wide range of turning operations
- Grinding and Polishing: Mirror-like surface finishes (Ra ≤ 0.1μm) reducing demolding resistance
- Heat Treatment: Vacuum quenching and nitriding combination ensuring no oxidation or deformation while increasing surface hardness and wear resistance
