Product Details

Automatic PET Preform Plastic Injection Molding Machine

Features:

The RMZ series adopt high efficiency motor and pump control technology. It accomplish high energy saving, high precise, high response, low noise and easy to be controlled. Under ideal situation, the energy saving could be 40% better than various pump and even 70%~80% better than traditional pump.

In addition, the machine adopts highly sensitive pressure feedback equipment. The close loop design helps the machine move more precisely and stably. Besides, the motor only work when necessary and it won’t create extra heat and that will lower the oil temperature. Sometime the hydraulic oil even doesn’t need to use extra power to cool down. And this helps the machine to save more energy.
