Plastic parts processing, in order to obtain accurate injection molding products, plastic parts processing size, precision and surface roughness have certain requirements, the specific requirements are as follows:
First, precision. There are many influential factors, such as mold manufacturing accuracy, plastic composition and process conditions.
Surface roughness. Determined by the roughness of the mold surface, so the general mold surface roughness than products to the lower level, mold surface to be introduced to grind polishing, through the product requirements mold cavity and core surface finish to be consistent.
Third, size. Mainly meet the requirements of the use and installation requirements, but also to consider the mold processing and manufacturing, equipment performance, but also to consider the fluidity of plastics.
