Hot runner technology is used in plastic injection mold runner system is an advanced technology

Hot runner technology is used in plastic injection mold runner system is an advanced technology . Hot runner technology used since 1946 since the nozzle extension from the initial to shorten the main channel in the form of a plastic surface condensation to use a thermal insulation principle, development become extinct hot  Instrument needle valve  adiabatic nozzles and other forms of pit . Although these forms compared with cold runner systems each have advantages, but there are still some deficiencies still are , especially for some of the Yi salivation plastic ( such as nylon , etc. ) can not be better suited . With the advances in microelectronics technology , as well as mold temperature control machine development and use , to the hot runner temperature control and mold cooling to arbitrary control , whereby the hot runner technology to advance to a new stage of  Compression fitting . Hot runner nozzle according to the different structure of the system can be divided into open gate valve gate nozzles and nozzle . For valve nozzle has a variety of products available abroad , but domestic targeted research in this area is also very little. Based on this situation , the paper and its needle -gate hot runner injection mold application are discussed. And molds molten resin flow channel had previously compacted to a certain extent . When the mold is closed and locked back after the gate valve needle instantly open the pre-compressed molten resin into the mold cavity filling fast .
