Holding connector mold parts pressure is used in fingerprint cavity was filled pressure. Connector mold parts role is to fingerprint cavity melt to the cooling under pressure. In this way, the appearance of the product development of dimensional tolerances can be guaranteed, the amorphous connector mold parts, depends largely on the packing pressure and the pressure holding time. In general, injection molding, filled to 95% - 98% cavity, to the packing stage. When connector mold parts filling of less than 90% will advance into the holding pressure time, holding pressure, in addition to the mould fill also need to melt the compaction and get qualified product. This makes the molding in the injection period, its weight and size by holding pressure effect is very big, not easy to stable. If the cavity is filled to 95% -98% into the packing stage, which reduces the pressure of the pressure value. The general connector mold parts production, packing pressure and injection pressure is 25% - 65%. In the actual production, some special products, such as thin-walled products, high precision connector mold parts gear injection parts, PMMA resin and thick wall products, packing pressure of injection of more than 90%, or even higher than the injection pressure. And as some easy to produce burr, flash products, to avoid the burr problem of product packing stage can be very low rate of fire and beyond the injection pressure high pressure at the same time.
