Custom Precision Non-Standard Stamping Die Punches with ±0.005mm Tolerance
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.
Materials--Premium Tool Steel for Precision Mold Parts | Sourced 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 Böhler,Let me break it down for you:
For H13 Hot-Work Steel:
We go with Bohler Uddeholm® material, which has exceptional thermal fatigue resistance. This makes it perfect for high-temperature injection molding applications like automotive molds and complex cavity inserts. Every batch comes with full traceability, so you know exactly where it's coming from.
For Stavax® ESR (420 Stainless Tool Steel):
This one’s sourced directly from ASSAB® and comes with mill test reports. It’s great for surgical instrument molds and transparent plastic components because of its superior corrosion resistance and ability to achieve a mirror finish, ideal for medical and optical-grade molds.
For M340 High-Hardness Steel:
We get this premium-grade steel from leading European suppliers. It offers extreme wear resistance and maintains precision even under heavy-load cycles, making it 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.
