Energy Solutions

1. Apply the product:

Plastic injection molding machines, die-casting machine, blowing bag machines, hydraulic machines, extrusion machines, shredders, extruders, sealing and cutting machine, molding machine, film blowing machine, bag machines, blow molding machines, hydraulic presses, and many other devices.

2. Rationale:

Injection molding machine energy consumption, probably divided into four parts:

3. Frequency advantage

• First, the overall power savings of up to 25 to 65%, improve performance, accelerate investment cost recovery.
• Second, to reduce motor starting current, more significant than when generator power.
• Third, the hydraulic oil temperature significantly lower (5 ~ 15 ° C) to extend seal life and reduce the amount of cooling water elimination Mao.
• Fourth, the smooth start, eliminating hydraulic shock, reduce noise and equipment failure rate.
• Five, under certain molding conditions, shorten the production cycle, increase production efficiency.
• Sixth, the modified constant operation without re-education study.
• Seven, do the switching frequency and the mains, when the controller is abnormal or unable to clarify the attribution of responsibility, you can switch the mains; if the inverter abnormal, can remove the service, does not affect the utility control and productivity.
• Eight, injection machine Express Signal Source:Voltage DC 0 ~ 10V; Current (0 ~ 1A, 0 ~ 2A, 0 ~ 3A, 0 ~ 4A, 0 ~ 5A).Nine, energy-saving mode selection module mention strength, according to different pieces of the mold transfer parameter selection intensity, for a variety of hydraulic pumps (vane pumps, gear pumps) features to the series plus AC reactor (ACL) and the DC reactor (DCL) to suppress the power of low frequency harmonic currents and to prevent interference, can improve the power factor, poor working conditions and isolation.

4.The injection molding process:

• In packing, cooling, the standby process, injection molding of a relatively low power consumption. Hydraulic pump electric injection molding machine as a whole accounted for more than 75% of electricity consumption. Because quantitative hydraulic pump injection molding machine only a fixed amount of oil, but most of the injection molding conditions oil oversupply, a large excess of high-pressure hydraulic oil all through the relief valve reflux, resulting in waste of energy. Oil pressure had become elevated due process, large amounts of energy consumed by the temperature rise and exacerbate a variety of valve wear. Because temperature rise often need extra cooling supply cooling water system caused a waste.

• Quantitative pump injection molding machine injection molding machine modified energy-saving cabinet control panel settings according to injection molding machine set the speed and conditions

• Pressure commands into 0 ~ 10V voltage signal or 4 ~ 20mA current signal injection machine energy-saving cabinet and so commandHydraulic pump motor speed control, regulation and control of the output of each molding operation pump oil to make realistic demands, the overflow traffic to a minimum, which can effectively save energy.
