HID618A Series, AC Frequency Drive, Frequency Converter, Inverter, Transducer, Injection Molding Machine

Power Range: 5.5kW~11kW/380V

Product Description

Hiconics HID618A Series VFD adopts the most advanced and mature vector control algorithm at the present and special controlling card for injection molding system is used in the machine for the controlling of gas-electric hybrid injection molding system. It has been through a series of strict tests like group pulse test, EMC test and vibration test and could adapt all kinds of bad working environments. With relatively high pressure responding speed and pressure keeping precision, our products could meet the demands of taking shape rapidly and precisely and saving energy as well.

Application Field

Injection Molding Machine, Oil Compressor, Shoe Making Machine, Die-casting Machine, Brick Manufacturing Machine, Material Extruder, Blowing Machine, Packaging Machine, Bending Machine, Cutting Machine, etc.

Working Principle of the System

The hydraulic servo system is composed of servo drive, servo motor, oil pump, pressure transducer, injection molding machine, etc. It uses new type servo control technology of building control method of flow and pressure to instead of constant volume pump valve control method of traditional asynchronous motor, which could not only reduce the electrical energy consumption of the system but improve the working efficiency and lengthen service life of the system as well.

Function Features

1. Saving cost

• Paralleling combination technology of multiple pumps is adopted to get large current flow to drive large machine, which could reduce cost.

• Energy consuming components of proportional pressure valve and proportional flow valve are completely removed to simplify hydraulic pipeline.

• The built in braking units could reduce the installation size and save cost as well.

2. Simple Operation

• Smart control System introduced in the VFD could ensure a direct use of the product without debugging or maintenance process.

• LED/LCD operation panel could save the changed parameter automatically.

   

3. Low Noise

The noise could be quite low during the running process and it could be even lower while in slow running process, usually less than 70 decibel.

4. High Reliability

• Best protection control could make sure that the system run to the largest extent in a short time.

• The drive has been through Antijamming processing and PG card could adapt various kinds of bad working environments.

• The product is suitable for the AC voltage from 310v to 420v and could meet the demands of varied grid or voltage of different area in China.

   

5. Lengthening Service Life of the Product

• The oil temperature rise of the system is largely decreased and the use of cooling water could be avoided or reduced, which could lengthen service life of hydraulic components.

• Various protective functions like over-voltage, over-current and default phase to the motor could lengthen service life of the machine and mould.

• The impact of unlocking or locking mould is largely reduced and service life of the machine and mould largely lengthened.

   

6. Saving Energy

The output flow of traditional constant flow pumps is fixed and could not be adjusted according to the actual demand. When the load needs a relatively small flow, the unnecessary flow will flow back to the oil tank with the help of proportional current valve and proportional voltage valve, which will waste a lot of oil. However, the hydraulic servo drive could direct the oil pump to offer oil according to the actual demand, which could avoid the situation of waste of oil and will save 40%-65% energy and 80% at most compared with constant flow pumps.

7. Perfect Performance

• Various methods like vector control, fuzzy PID, pump leak oil pressure compensation are adopted to ensure a high precise of plastic injecting place within ±0.3mm, fluctuation of pressure less than±0.5bar, responding time of the system as low as 0.05s. Both working efficiency and qualified rate of the product are improved.

• The output current and output torque is 2.5 times that of the rated value, thus could make sure that the machine would not jump during high pressure plastic injecting process and heavy load process and keep a good quality of the products.
