followed the principle container seals

container seals injection time, packing time and cooling time must be set according to the product thickness, mold temperature, the material properties. Injection time setting generally slightly larger than the screw to complete the injection stroke time to move, Security seals long injection time will not only produce mechanical wear, increased energy consumption and other negative effects, but also to extend the molding cycle. container seals as long as sufficient power to achieve the required injection velocity, so that the cavity can be filled with the melt smoothly, excessive pressure tends to produce stress in the article; however, at higher dimensional accuracy of the molded article, in order to prevent product shrink over, you can use Barrier Seals the high-pressure injection to reduce shrinkage products after release. Injection speed will affect the appearance of the quality of the product, container seals its setting should be set according to the mold geometry, exhaust status, usually in the premise of ensuring good appearance, try to increase the injection rate to reduce the filling time.
