Servo System

Injection Molding Machine with Servo Drive will be future trend in the market, and reconstruction of standard(fixed pump) or even variable pump machine to ones with servo system is now a popular and profitable investment.

Servo System Features

1: Energy Saving and Cost Reduction

Case of customer: The electric power charge of a machine was 70,000 RMB/year,after reconstruction the charges was reduced to 35,000 RMB/year for paticuler working condition, the charge was even reduced to 7,000 RMB/year. This means the money invested can be withdrew within a year.

2: High repeatable accuracy and High pass rate of products

Through accurate feedback control repeatable accuracy can be improved and the pass rate of products will be enhanced.

3: Enable the machine to produced precisions products

System provides accurate feedback control and rapid response speed. Some of the precision products which cannot be produced by the original machine now can be produced.

4: Lower Noise

The noise of the system can be reduced approximately from 80dB to 65dB by using crescent gear pump.The comfort index of the working environment can thus be improved.

5: Lower system oil temperature, longer service life of the machine

Servo system can provide oil according to the actual need, no overflow occurs, thus the oil temperature of the system can be reduced, maintain cost can be reduced and the life of machine can be extended.

6: Reduction of the water usages

The water usages amount can be reduced due to low oil temperature.

7: Saving charges from increasing electric capacity Due to high energy saving ratio, the electricity load is reduced after reconstruction increasing electric capacity would not be necessary.

Characteristics of Servo energy-saving injection molding machines

1. High energy saving: In an ideal working state, compared with conventional injection molding machines,

their energy saving can reach 50%-80% with servo system.

2. Better Molding Stability: Compared with conventional injection molding machines, repeatability is

greatly improved due to servo motor close-loop control.

3. Quick response: due to sensitive servo motor, the response time is only 0.05 second.

4. Quiet & low noise: The machine runs with low noise, and will be much quieter in a low speed.

5. Reliable holding pressure: Compared with all electric injection molding machines, the time for pressure

holding will be much longer and steady.

6. Slow Oil temperature rise: Servo motor proportionally deliver hydraulic oil base on our needs, it can

prevent unnecessary heat being generated, even in some cases does not require cooling.

Comparison table of dynamic control system’s precision grade and energy

saving grade of hydraulic injection molding machines:

CHARACTERISTIC ENERGY SAVING GRADE

Constant pump+close-loop PQ proportional valve /

Constant pump+PQ proportional valve

Variable pump (close-loop type) 20%-40%

Variable pump (open-loop type)

Gear pump frequency conversion electromotor 30%-50%

Servo motor dynamical control system 50%-80%

WARRANTY

Our system covers warranty for one year from the date of commissioning against manufacturing defects.

Mal functioning, mishandling or any electricity disorder will not attract this warranty clause.

We shall provide free of cost service during warranty period except the buyer will have to arrange

boarding and lodging of visiting engineer. The buyer has to provide complete detail of complaint on

mail to enable us to identify nature of complaint before sending engineer.

Servo System Energy Saving Principle

The uniqueness of the injection molding machine’s requirement for flow: discrete flow

recycles.

Ordinary Machine

Using fixed flow delivery system, the flow supply exceeds the machine’s demand, much

overflow occur when operating thus huge waste of energy cannot be avoid.

Servo Machine

Using servo control system the flow supplies according to the machine’s demand. 1. The Servo motors stops rotating during cooling, so the system does not consume energy. 2. In pressure retaining the servo system output experience very little internal leakage of hydrologic oil refreshing system

with minimum power consumption. 3. The system runs substantially without overflow loss or useless consumption of Energy.

SES Servo Drive

Advantage of the SES Servo Drive 1:- Excellent voltage compatible range: 330V-528V three phase alternating current input.

2:- Built in break unit in all series , less space occupied.

3:- Parameter storage panel , allowing mass test and convenient system replacement.

4:- Both KTY and PTC overheating protection are incorporated.

5:- Optional PID control, better solution for the problem that the flow decreases when the

p ressu r es r ea ch es i t s instruction. This solu ti on is testified by an contrast

experiment with other brand of servo system – when manufacturing high hardness plastic

such as PC, our system shows better performance.

6:- Supporting distributed control of multiple servo system confluence and compound

control of distributaries and confluence.

Ses Servo Motors

Advantage of SES Servo Motor 1:- Double Cooling-down design: The combination of air cooling and water

cooling

Lets understand this by following diagrams .

As shown in figure 1 , The cold air from the motor rear will become hot as it reach the fore

part due to heat exchange of the motor. And combined with the heat conducted from the

pump, the actual temperature of the motor’s for part will be much higher than that of rear.

Service lives of the bearing will thus be shortened.

As shown in figure 2, water cooling design for the fore part can effectively reduce the

temperature of this part and both the motor and the sealing equipment of pumps are

protected.

2: Low Interior Rotor

Short service of the bearing and heat demagnetization are two major defects of the servo

motors.

Large inertia is the main cause of thses problems. On the other hand large intertia leads to

large impact to the bearing in the rapid acceleration, deceleration and backward-forward

roatating processes, which will shorten the service life of the bearing.

On the other hand large intertia required large current in both acceleration and

deceleration processes which causes more heat and finally leads to heat

demagnetization.

To resolve the problem , unique hollowed-out design is adopted for SES servo motor sheets

which makes these motors much lighter then the ordinary ones and thus the problem

mentioned above can be easily avoided.

Interior installation of the maganetic steels is adopted to guarantee that the magnetic steels

never be detached when the rotor running in high speed.
