The Influence of the Weld Line and the Selection of Mold Gate Location

Through injection molding simulation software and examples of injection,This paper analyzes the causes of the weld line when injection molding products, the impact on the quality of products, analysis of the injection mold gate location selection problems and defects produced by principle, think weld line has a great influence on the quality of injection molding, on this basis, put forward in view of the weld line, the influence of the mold gate location selection method in the practical work of is: reasonable choose the location of the gate, to control the degree of weld line, as far as possible to reduce the number of the weld line, or make them produce not important position in the mold.
