400 Ton Injection Molding Machine

The 400 ton injection molding machine has a clamping force of 4000KN, and the 400 ton large screw machine is about 1000 grams, and the maximum can reach 700~800 grams. The products are different, and the results are different.

The parameter table of the ZOWEITE® 400 ton injection molding machine is shown in the figure below:

The ZOWEITE® 400 ton injection molding machine can be used to make barrels: plastic barrels, oil barrels, paint barrels, etc./fruit and vegetable baskets/plastic preforms/pipe fittings/lampshades/egg trays/auto parts.

What are the reasons for the high temperature of the 400 ton injection molding machine? What is the solution?

1. The temperature rise of the 400-ton injection molding machine is too high:

1. Choose hydraulic oil with poor viscosity, high viscosity, high viscous frictional resistance, and low viscosity, and leakage will expand. Both conditions can cause hot and heat up.

2. The pressure adjustment of the hydraulic transmission system is much higher than the specific one. Sometimes it is due to tight sealing, or due to the damage of the hydraulic seals, and the expansion of the leakage. It is necessary to increase the working pressure.

3. The quality of component installation is poor, and the friction loss of mechanical equipment between relative speeds is large

4. The general unloading circuit of the system software has common failures or because the unloading circuit is not set, the oil pump cannot be unloaded when it stops working. All the total flow of the pump overflows under high pressure, causing overflow loss and hotness. Cause to heat up.

5. The volume of the fuel tank is small, the total area of heat rejection is insufficient, and the volume of the refrigeration equipment is too small.

6. The climate and working temperature are high, which causes the oil temperature to rise

7. The mating gap of the mating parts is very small, or the gap is too large after the application is worn out. The external leakage is large, resulting in a large loss of capacity.

8. The system software pipeline is too thin and too long, too many bends, part of the working pressure loss and pressure loss, the working pressure loss is large.

9. Select the oil system software provided by the variable of the oil pump volume according to the fast release rate. During work, most of the unnecessary total flow will overflow under the high pressure and the speed control valve will overflow and become hot.

Second, the ZOWEITE® 400 ton injection molding machine solution to the excessive temperature rise of the injection molding machine

1. Check if the gear oil refrigeration system is blocked

2. Improve the lubrication standard of fitness sports parts to reduce friction loss, which is beneficial to reduce the load during work and reduce heat.

3. According to different load regulations, often check and adjust the working pressure of the speed control valve to make it appropriate.

4. Improve the installation quality and accuracy of the hydraulic system and the hydraulic transmission system, strictly control the gap between the mating parts and improve the lubrication standard, select rubber seals with low friction resistance and improve the sealing structure to minimize hydraulic pressure The starting force of the oil cylinder to reduce the heat generated by the friction loss of the mechanical equipment

5. Effectively select gear oil, especially hydraulic oil viscosity. Under the conditions allowed by the standard, choose a lower viscosity as much as possible to reduce viscosity friction loss
