Rubber and Plastic Processing Machinery (Energy Saving Solution)
 
 
 
1. Applications
  
    Plastics injection machine, hollow forming machine, press casting machine, hydraulic machine, squeezing machine,
    crushing machine, extrusion machine, forming machine, sealing machine, film blowing machine, bag blowing machine,
    bag weaving machine, hydraulic press machine etc.

2. Basic principle
 
     The energy consumption of injection machine is divided into 4 parts:
  
Main power equipment % of Power consumption Energy-saving 
by inverter
Power consumption for 
oil pump of hydraulic system
75 - 80 %
Power consumption of 
heating system
10 - 15 %
Power consumption of 
cooling water pump
5 - 10 %
Power consumption of 
other signal controller
1 - 5 %

     A hydraulic pump uses over 75% of total power consumption. Although the amount of oil applied by a hydraulic pump
     is fixed, the demand of the oil during the injection process is varied. By stallingthe inverter technology, the power
     consumption can be obviously reduced, and the production efficiency can be improved.

1.Save up to 25-65% of total power consumption. Improve the production efficiency. Accelerate the investment return.

2.Reduce the starting current of a motor. Scenario can be seeing significantly when a power generator is used.

3.The hydraulic oil temperature obviously drops 5°C-15°C to extend the lifetime of oil seal, and also to reduce the consumption of cooling water.

4.Smooth start to reduce the hydraulic pressure impact. Effectively reduce noise and equipment failure rate.

5.Shorten the production cycle and increase the productivity under specific molding conditions.

6.After installing the inverter, the operational process is as same as before.



Actually, the pressure, flow rate of injection machine is varied at lock mold, injecting,cooling, open mold, pin inject,
and clearing. During time of mold open , cooling and clear, inverter could lower the RPM of oil pump, eliminate oil
overflow and the temperature of hydraulic oil also can be reduced at the same time.

►Save the power output generated by one Kuguan Reservoir per year

There are 50000 injection machines in Taiwan. If Rhymebus's inverters are installed on them, the power
(0.5 billion kWH/year) generated by Guguan Reservoir can be saved and 314000-ton carbon dioxide can be
 reduced according to 33% energy-saving rate.
