Research on the Weld Line's Reduction of Injection Molding

Abstract:

This document describes the principles of the weld line’s generation, formation and points out that the impacts of the product mix, mold structure to the weld line. And a new method of improving products’ weld line was proposed, it adds the plastic materials to the plastic product and loads the insert to the mold to improve the weld line, actually, weld line’s quality was determined not only by adding rubers, loading inserts, but also by other complex methods; However, the approach that was proposed by this paper could solve the weld line’s quality easier than other methods, for it can greatly remove the weld line of the product’s appearance and do not need complicated process parameters. Then the Moldflow software was applied to stimulate the filling process and As a result, the weld line was greatly improved.
