Yirongsheng Technology Co., Ltd. specializes in manufacturing precision plastic injection mold parts, including core cavity sets with thread functionality. These components form the foundation of injection molds, directly impacting final product quality through dimensional accuracy, surface finish, and precise fit tolerances.

Our threaded core cavity sets utilize premium S136 steel from ASSAB for exceptional polishing performance. Thread production employs CNC lathe and grinding equipment, while bushings use 1.2344/8407 or copper materials to ensure extended service life and meet high-gloss requirements for cosmetic tooling applications.

The core forms the internal shape of molded parts (male component), while the cavity forms the external shape (female component). These paired components create the mold cavity where plastic is injected.

The core and cavity create the mold space where molten plastic is injected. The material fills the gap between core and cavity, then hardens into the final product shape with precise dimensional accuracy.
