precision injection molding molding features is;
injection molding parts dimensions requirements degree high, small. need to precision injection molding requirements must need to conditions is: 1, mold material need good, rigid property 足, type dimensions degree, light degree 以入模 sheet/plate 间 定位精 degree need high.
2, need using/adopting precision injection molding machine.
3, need selection combined precision injection molding 工世 材 material. commonly used precision injection molding material large more has below/following types: POM, POM+CF（DMD carbon fiber ）, POM+GF（ glass fiber (GF) 维）, PA, FRPA66（ reinforcement PA）, PBT, PC and other. precision injection molding process in need ensure injection molding parts dimensions degree important methods is control injection molding parts issues, its in has: injection molding parts hot shrinkage, versus shrinkage, orientation shrinkage and pressure shrink shrinkage and elastic property 回复. injection molding features is: for injection molding parts dimensions degree requirements high, generally is can is standards, for injection molding parts appearance requirements versus comparison relatively high, necessary can can utilizing processing （ ratio 如喷油） improvement appearance upper defect. 普通注 plastics molding need use especially precision injection molding machine, need especially 提定 材 material, generally commonly used thermoplastic property plastics can use production. therefore injection molding in plastics industrial in by application.
