High-Precision Custom Mold Inserts in H13 / 1.2344 / Dievar Steel with 0.005mm Accuracy for Injection Molding
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.
We use 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.
Sourced directly from ASSAB® with mill test reports. Excellent for surgical instrument molds and transparent plastic components due to superior corrosion resistance and ability to achieve mirror finish, ideal for medical and optical-grade molds.
Premium-grade steel from leading European suppliers offering extreme wear resistance and maintaining precision 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.
5-axis CNC machines achieving tolerances as tight as ±0.005mm, forming complex surfaces in one operation for precision and efficiency.
Precise electrode discharge technology for intricate structures like deep slots and narrow gaps, providing high accuracy while preserving tool life.
Ultra-smooth finishes with minimal surface roughness, perfect for optical components and high-precision molds.
Reliable precision and performance for wide range of turning operations, ensuring consistent quality and high productivity.
Mirror-like surface finishes (Ra ≤ 0.1μm) reducing demolding resistance and improving production efficiency.
Vacuum quenching and nitriding combination ensuring no oxidation or deformation while increasing surface hardness and wear resistance.
