高光无痕注塑模具材料选用思考

Consideration on material selection of high-gloss non-marking injection mold

高光无痕注塑能解决塑件出现熔接痕、气痕、变形、内应力、表面光洁度达不到要求等缺陷,已在家电和汽车等行业广泛应用。本文讲述了高光无痕注塑定义和模具具体要求,结合业内同行使用高光无痕注塑模具情况,重点描述了高光无痕注塑模具选材的类型,对目前常用几种模具钢基本性能和应用做了较详细的介绍,旨在指导高光无痕注塑模具材料选用,供大家思考。

High-gloss non-marking injection molding can solve the defects of weld line,gas mark,deformation,internal stress,poor surface finish and so on.It has been widely used in household appliances and automobile industries.This paper describes the definition and mold specific requirements of high-gloss non-marking injection molding.Combined with the situation of using high-gloss non-marking injection mold in the industry,it mainly describes the types of material selection for high-gloss non-marking injection mold,and introduces in detail the basic performance and application of several commonly used mold steels,aiming to guide the selection of high-gloss non-marking injection mold materials for everyone's consideration.
