Holding pressure and time near the end of the injection molding process, the screw stops rotating, just move forward, at this time of injection into the packing stage. Packing process in the injection molding machine nozzle continuously fed into the cavity to fill the vacated due workpiece volume contraction. If the cavity is filled without packing, large parts dating shrink about 25%, in particular due to the contraction of the muscle is too large and the formation of shrink marks. Holding pressure is generally about 85% of the maximum pressure Baoan filled plastic products, of course, be determined according to the actual situation. Stripping stripping stage is a plastic injection molding cycle in the last link. While the products have been cold-molded plastic products Fukunaga, but the release is still very important to the quality of the products influence, improper stripping method may result in product during stripping uneven force, deformation and other defects caused by the product ejection . There are two main methods of stripping: stripping ejector and the stripper plate mold. To choose the right way to design mold releasing According structural characteristics of products to ensure product quality. For the selection of a mold releasing jack, the jack should be uniform set of high-quality plastic products suppliers, and the location should be selected in the release resistance and maximum strength and stiffness of plastic parts where the biggest plastic products, in order to avoid damage to the plastic deformation. The stripper plate is generally thin-walled containers for deep cavity and does not allow transparent products putter traces of mold release characteristics of this mechanism is that the release force and uniform, smooth movement, no obvious traces left.
