If the temperature of the injection machine is too high, it can indeed cause material degradation. The heating temperature of the material cylinder is one of the key parameters in the production process of injection machines, which directly affects the melting state and processing performance of plastic materials. When the temperature is too high, plastic materials undergo a series of complex physical and chemical changes, leading to degradation.
Specifically, plastics are prone to thermal decomposition reactions at high temperatures because polymer chains can break and produce lower molecular weight products such as gas, oil, and carbon black. The generation of these products not only changes the original properties of plastics, but may also cause damage to the equipment and molds of injection machines. In addition, high temperatures may also cause additives (such as antioxidants, stabilizers, etc.) in plastics to become ineffective, further accelerating the degradation process of plastics.
The reasons for high temperature in injection machines may include out of control heating system, temperature controller failure, mismatched or damaged thermocouple types, etc. To avoid this situation, operators should strictly control the heating temperature of the injection machine to ensure that it fluctuates within a reasonable range. At the same time, regularly inspect and maintain key components such as heating systems, temperature controllers, and thermocouples to ensure their normal operation and accurate temperature control.
