For the current production of large molds repair mode more often, gate selection is unreasonable, long molding cycle parts

Currently, the traditional large-scale injection mold design no basis in theory, lead to its presence in the design and manufacture of a series of problems encountered in the process. For example gating system balance workpiece warpage, cooling not guarantee the quality, weld lines and air pockets and so on. Taking a front bumper injection mold design, for example, by summarizing a large injection mold design principles and  Stainless steel needle valve  for the current production of large molds repair mode more often, gate selection is unreasonable, parts molding cycle is long, the number of cavitation more and molding defects such as weld lines, the use of  2 way manifold  software PRO / E for the car bumper design and mold flow analysis software application for car bumper parts for injection molding process optimization. In this paper, the following work on the bumpers of large injection mold for molding parameters gating system design and optimization.
