Compression tooling requires pressure from press machine to get material molding, then get the products. Normally speaking, we will calculate the pressure based on 3D model prior to molding.
Compression tooling is mainly consist of cavity and core with ejection system. In comparison with process of injection molding, compression tooling is easier to get shear edge damaged, if it’s not hardened. In that case, we need to harden the shear edge by laser, also polishing on cavity side is very critical.
Due to small or even ignored shrinkage by compression tooling, the dimension of molding parts have high accuracy, scarp rate will be lowered down, and production high effective. In recent years, MDC Mould has produced variety of compression toolings in Automotive industry, automotive mould also is MDC’s main business, such as underbody shield, top cover panel,etc.
