Precision Mold Core And Cavity In Injection Molding 48-52HRC Hardness
S136 Precision Mold Core Inserts Cavity Inserts For Precision Injection Molding
Compared with other molds of packing products, cosmetic molds have higher requirements on appearance, especially for lipstick tubes, mascara tubes, and transparent caps. Mold Core and Cavity serve as the heart of the mold, where their quality, surface finish, and fit directly impact mold performance.
Our solution utilizes S136 from ASSAB with excellent polishing performance for cavity production. Threads are produced by grinder, and bushings use 1.2344/8407 or copper to ensure service life and meet high gloss requirements for cosmetic molds.
