Precision Core Pin with 0.003mm Accuracy for Medical Industry Using STAVAX

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.

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.

• Roders CNC Machining: 5-axis CNC machines achieving tolerances as tight as ±0.005mm, forming complex surfaces in one operation
