High-Precision Connector Mold Component Made of 1.2312 Mold Steel with 0.005mm Accuracy and Polished Surface 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.

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.

Our state-of-the-art manufacturing techniques ensure micron-level accuracy in all our precision mold components.
