Cooling Of China Pet Bottle

It is necessary to provide a flow path in the injection Pet Preform mold to connect the nozzle (of the injection molding machine) to each precision point. This flow pattern is the interior of the feed system. Typically the feed system includes gates, runners, and gates. These terms apply equally to the flow path itself, as well as to molded materials that are removed from the flow path itself during the extraction of the molded article. It can be seen that the material passes through the gate, main runner, branch runner and gate before entering the stamp. As the molten plastic passes through the gate and the runner, the temperature decreases and the viscosity rises, so the viscosity is reduced by the shear heat generated when the cavity is filled through the gate. It is desirable to keep the distance that the material must travel down to minimize pressure and heat loss. For this reason, the layout of the stamp and the design of the gate must be carefully considered. slag The gate is a passage for transferring molten plastic injected from the injection molding machine nozzle to the mold. It is part of the runner of the sprue bushing and is the part that separates from the mold. runner The flow channel is the channel for introducing molten plastic into the mold cavity door The gate is the inlet of molten plastic into the cavity. The gate has the following functions: restricting the flow and direction of the molten plastic; simplifying the cutting and forming of the flow path, simplifying the finishing of the part; rapidly cooling and solidifying to avoid reflow after the molten plastic fills the cavity Cold section The purpose of the cold section plug opposite the injection port is theoretically to receive material that is cooled at the front of the nozzle during the cooling, cooling and injection phases. More importantly, it provides a positive way to pull the gate out of the sprue for jetting purposes. Gates, runners, and gates will be discarded when the part is completed. However, runners and gates are important items that affect part quality or cost. Jilian Molding from Huangyan, China, is an expert in China Pet Bottle. We have a wealth of experience in this area.
