Five major hazards to injection molding machine ca

Too high temperature rise brings five hazards to the injection molding machine

the injection molding machine is the processing machine used the most in the plastic processing industry. There are not only a large number of products that can be directly produced by the injection molding machine, but also the key equipment that constitutes the injection, drawing and blowing process. In the process of injection molding, many enterprises will find that the temperature rise of the injection molding machine is too high, which actually does great harm to the injection molding machinery and equipment. Specifically, it will bring the following five hazards:

one of the hazards: lead to thermal deformation of the machinery. The difference of thermal expansion coefficient in the hydraulic components also damages the visual acuity. The lower base weight moving components are stuck due to their smaller cooperation internship, causing action failure, affecting the transmission accuracy of the hydraulic system, and leading to the deterioration of the working quality of the components

hazard 2: it leads to the decrease of oil viscosity. If the temperature of the injection molding machine is too high, the viscosity of the oil will decrease, the leakage will increase, and the volumetric efficiency of the pump and the efficiency of the whole system will decrease significantly. Because the viscosity of the oil decreases, the oil film of moving components such as slide valves becomes thinner and cut, and the friction resistance increases, resulting in increased wear

hazard 3: change the shape of rubber seals. Too high temperature of injection molding machine will lead to deformation of rubber seals, accelerate aging failure, reduce sealing performance and lead to service time, causing leakage

hazard 4: accelerate the oxidation and deterioration of oil. Too high temperature rise of the injection molding machine will accelerate the oxidation and deterioration of the oil, precipitate asphalt, and reduce the lead time of the hydraulic oil. The precipitates block the damping holes and slot valve ports, causing the pressure valve to be stuck and unable to move. The biggest driving factors are the work of the express industry, the elongation and bending of metal pipelines, and even cracking

hazard 5: it leads to the decline of the working quality of components. Too high temperature rise of the injection molding machine will reduce the working quality of components, and dissolved air in the oil will escape, resulting in cavitation, which will reduce the working performance of the hydraulic system
