Automatic Plastic Injection Molding Machine PET Bottle Preforms Making 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.

Machine Features

-High Energy saving Under the ideal working state, Power consumption is 40% less than that of variable displacement pump and 70% less than that of fixed displacement pump, save the cost effectively.

-High precision Precise control of low pressure & low flow, repeating precision is less than 0.5%. Weight error of the products is 0.4%~0.7%, with semi-close loop system nearly.

-Fast response With steady capability, servo gearshift dynamical control system has equipped with pressure feedback device with high precision and sensitivity, which forms close-loop precision control, cycle time effectively shortened and improving production efficiency.

-Low noise Different from ordinary fixed pump injection molding machine, servo power-saving injection molding machine is working only when necessary. And working noise 70dB,will be much quieter for your working area.

-Oil temperature rise slowly The system can restrain arising of oil temperature, so smaller oil cooling system can be used in the machine.

-PQ control Control pressure and flow simply by inputting simulated voltage of pressure (P) & flow (Q) into the computer.
