The injection molding machine heating and cooling

- Feb 05, 2021-

The heating system is used to heat the barrel and the injection nozzle. The barrel of the injection molding machine generally uses an electric heating ring as a heating device, which is installed on the outside of the barrel and is detected in sections by a thermocouple. The heat conducts heat conduction through the wall of the cylinder to provide a heat source for the plasticization of the material; the cooling system is mainly used to cool the oil temperature, too high oil temperature will cause a variety of faults, so the oil temperature must be controlled. The other location that needs to be cooled is near the feeding port of the feed pipe to prevent the raw material from melting at the feeding port, causing the raw material to fail to be fed normally.
