Hot Runner Systems are heating component systems used in injection molds that inject molten plastic particles into the cavity of the mold. Hot runner mold is a new structure that heats the runner and runner of traditional mold or three-plate mold, and does not need to remove the runner and runner at each forming.
The hot runner system is generally composed of hot nozzle, shunt plate, temperature control box and accessories. There are two kinds of hot nozzles: open hot nozzles and needle valve hot nozzles. Because the form of hot nozzle directly determines the selection of hot runner system and the manufacture of mold, the hot runner system is often divided into open hot runner system and needle valve hot runner system accordingly. The shunt plate is used in one - mode multi - cavity or multi - point feed or single - point feed with offset level. The material is usually P20 or H13. The diverter plate is generally divided into two categories: standard and non-standard. Its structure form is mainly determined by the distribution of the cavity on the mold, the arrangement of the nozzle and the position of the gate. The temperature control box includes a host, cable, connector, and cable socket. Hot runner accessories usually include: heater and thermocouple, runner sealing ring, connector and junction box, etc.
