Injection machines can operate for long periods of time under high temperature conditions, but it is necessary to ensure that the design and maintenance of the machine can support such working environments. The operation of injection machines at high temperatures is usually to heat plastic materials to melt them for injection into molds. However, the impact of long-term high-temperature operation on the machine cannot be ignored. Firstly, the heating system of the injection machine needs to have sufficient high temperature resistance to ensure that components such as the barrel, screw, and mold can withstand high temperatures without damage or deformation. Long term high-temperature operation may lead to excessive wear or aging of heating elements, and even cause heating system failures. Secondly, under high temperature operation, the lubrication system of the injection machine may fail due to excessive temperature, leading to increased friction and wear of components, and shortening the service life of the machine. Therefore, during prolonged high-temperature operation, it is necessary to maintain appropriate cooling and lubrication to ensure that the machine temperature is controlled within a safe range, and regularly check the working conditions of the heating system, hydraulic system, and lubrication system to prevent malfunctions caused by overheating. In addition, the degradation of materials and accumulation of residues during long-term high-temperature operation of injection machines may also have adverse effects on the machine, increasing maintenance complexity and costs.
