plastic injection mold making of features and trends

Features and trends of plastic injection mold making 

(1) The cavity and core are three-dimensional surface

(2)High precision

Forming parts IT8~9, precision mold forming parts IT6~7, with partial accuracy IT 7~8

(3) High surface quality requirements

Formed parts surface roughness RaO.2 ~ 0.1um, some face requirements for Ra'zum below the general need for manual grinding, polishing, accounting for 40% of the entire mold processing volume precision type mold more for the panel structure, manual processing volume of about 10%

(4) the performance of the tooling requirements are increasingly high

(5)The process is long

Multi-matching, many types of work, many processes, long process flow
