Hydraulic oil temperature is too high

Hydraulic oil temperature is too high

1. The oil pump pressure is too high: appropriately lower the working pressure according to the plastic molding process.

2. Insufficient oil in the tank: add enough hydraulic oil

3. The oil cooler has been used for too long and is full of scale. The cooling effect is poor. Clean the cooler.

4. The cooling water flow is not large enough, or the cooling water temperature is not low enough
