Analysis of Effect of Process Parameters on Warpage of a Automobile Bumper Injection Molded Parts

Article Preview

Abstract:

Take a automobile bumper for example, analysis of effect of process parameters on warpage of a automobile bumper, including melt temperature, injection time, cooling time and packing pressure, on the warpage of the automobile bumper were analyzed by means of Moldflow software. The results show the warpage decrease of the increase of the injection time, the cooling time and the packing pressure, but when the packing pressure reached 45MPa, the warpage slightly increased; the melt temperature should be picked out by the characteristics of the plastics material.
