Custom Tool Steel Injection Mold Parts with 0.005mm Accuracy and Polished Finish
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.
- H13 Hot-Work Steel: Bohler Uddeholm® material with exceptional thermal fatigue resistance, perfect for high-temperature injection molding applications
- Stavax® ESR (420 Stainless Tool Steel): Sourced from ASSAB® with mill test reports, ideal for surgical instrument molds and transparent plastic components
- M340 High-Hardness Steel: Premium-grade steel from European suppliers offering extreme wear resistance for high-volume production molds
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.
