Thick wall plastic shrinkage problem process skills
If there is sink mark on the surface of the thick wall, or in partial wall plastic parts, such as the introduction of gas assisted injection molding will be solved.
Gas assisted injection molding is made by the high pressure gas is introduced into the thick wall parts, parts inside the injection molded parts to produce hollow section, completely filling process, and realize the gas pressure, eliminate products of shrink mark a novel plastic molding technology. Traditional injection molding process cannot be combined thick wall and thin wall forming, and residual stress in large parts, easy buckling deformation, surface sink mark. Technology in the development of new internal hollowing out through the thick walls, successfully produce thick wall, partial wall products, and products appearance excellent surface properties, low internal stress. Light weight, high strength. Has now developed gas-assisted product structure and ?
