What to do if the temperature of the injection molding machine is too high?

As a Film Tapes Plastic Core Tube Exporter, share with you the reasons for the high temperature rise of the injection molding machine:

1. The volume of the fuel tank is too small and the heat dissipation area is not enough. The cooling device has too small a capacity.

2. The fixed pump oil supply system that selects the oil pump capacity according to the fast forward speed, during operation, most of the excess flow will return from the relief valve under high pressure and generate heat.

3. The unloading circuit in the system is faulty or because the unloading circuit is not set, the oil pump cannot be unloaded when it stops working. The entire flow of the pump overflows under high pressure, which causes overflow loss and heat generation, resulting in temperature rise.

4. The system piping is too thin and long, too much bending, local pressure loss and pressure loss along the process are large.

5. Insufficient component accuracy and poor assembly quality, and large mechanical friction loss between relative movements.

6. The mating clearance of the mating parts is too small, or the gap is too large after wear and tear, and the internal and external leakage is large, resulting in large volume loss. For example, the volumetric efficiency of the pump decreases and the temperature rises quickly.

7. The working pressure of the hydraulic system is adjusted much higher than the actual need. Sometimes it is because the seal is too tight, or because the seal is damaged, and the leakage increases, the pressure must be increased to work.

8. High climatic and operating environment temperatures cause the oil temperature to rise.

9. If the viscosity of the oil is selected improperly, if the viscosity is large, the viscosity resistance is large, if the viscosity is too small, the leakage will increase. We have Injection Plastic Plugs on sale.

High temperature treatment of injection molding machine:

1. According to different load requirements, often check and adjust the pressure of the relief valve to make it just right.

2. Reasonably select hydraulic oil, especially the viscosity of the oil. When conditions allow, use a lower viscosity as much as possible to reduce viscosity friction loss.

3. Improve the lubricating conditions of moving parts to reduce friction losses, which is conducive to reducing workload and reducing heat generation.

4. Improve the assembly quality and accuracy of hydraulic components and hydraulic systems, strictly control the clearance of mating parts and improve the lubrication conditions. The sealing material with small friction coefficient and improved sealing structure are used to reduce the starting force of the hydraulic cylinder as much as possible to reduce the heat generated by mechanical friction loss.

5. Check whether the hydraulic oil cooling system is blocked.
