Key Features

Description

Use of servo-motor and constant displacement gear pump can save energy by up to 70%.
2.The outward toggle design concentrates the clamping force on the mold platen which reduces deformation to a minimum.
3.The material storage motor is fixed to eliminate inertia.


Features

100 Ton Energy Saving Plastic Injection Molding Machine

Unique Servo Motor with Constant Displacement Gear Pump:
It features energy saving, silence, low-noise, low thermal growth, high response and high repeatability. The unit is a proven cutting edge that helps to lower production costs while creating more profits.


Energy Saving Plastic Injection Molding Machine High Response Servo Motor Driver:
The use of high response controller dramatically upgrades product accuracy and stability.


Energy Saving Plastic Injection Molding Machine ELIMINATING MOLD DEFORMATION :

Conventional toggle-Significant deformation New outward toggle-minimum deformation
of mold platen. of mold platen.

Energy Saving Plastic Injection Molding Machine Clamping Unit:
Ultra-high Rigidity Assures Increased Service Life of Machine and Mold.
The top and bottom outward toggles are concentrated at the center of machine frame, featuring extra long mold opening stroke and minimized deformation of mold platen.
This feature not only meets various product requirements, but also provides an increase in molding quality.


The machine frame is reinforced by using Pro-E computer-assisted stress analysis, assuring high rigidity, uniform stress distribution, no stress concentration problem and longer service life.
Energy Saving Plastic Injection Molding Machine LOW NOISE:
Noise level is as low as 68dB(A) at 140kgf retaining pressure. During idle running, no noise generated instead of noise caused by continuous running of a conventional motor.
Energy Saving Plastic Injection Molding Machine SYSTEM PACKAGE:
The system integrates electronic and electric devices, hydraulic and control software, making it easy to operate and maintain.


*The flow rate and pressure can be set according to actual requirement. Once the pressure reaches the set value, the motor will run at low speed, eliminating energy loss due to over-flow for saving power consumption considerably.
*Significant energy saving permits great reduction of injection molding cost.
High response of injection control can reach 99% repeatability. In addition, the linear error of injection speed is controlled within 1%.


Extra-high precision pressure control allows pressure linearity error within 1% between setting values and actual values is maintained.

*Energy Saving Plastic Injection Molding Machine HIGH EFFICIENCY HIGH ACCURACY:
The unit applies a cylindrical check seal to stop return-flow of hydraulic oil. When hydraulic pressure generates, the “moon”shape separated bronze presses against both sides of the gear. It automatically compensates gap to avoid leakage, enabling discharges efficiency to reach 95%~98%. In addition, with its low speed with high pressure feature, such as running at 100rpm with 200bar pressure, the unit is also capable of exhibiting high efficiency. It’s an excellent unit specially designed for energy saving and pressure-retaining for plastic injection molding machines.
With the use of a moon shape separated bronze in combination with pressure gap compensation and hydraulic balance design, there is no wearing problem and no particles. This results in minimum rippling wave(1.5%~2%), minimum noise and longer service life.
The effect of a conventional gear pump is its gear clearance, causing inaccuracy 12~16% of pulsation. This defect leads to more vibration, more noise and shorter service life.
*The servo motor is specially designed to meet the requirement of energy saving for a plastic injection molding machine. With the self-developed high-density magnet technology, the construction of the servo motor is greatly reduced with minimum rotor inertia.
*The principle is the same as a car; if a car requires faster acceleration and more fuel saving, the car weight must be lighter. Similarly, if a servo hydraulic drive requires faster raised pressure and more power saving, the rotor inertia of the servo motor should be as small as possible.

The purpose of Slider Kit is to gather common slideshow-like jQuery functionalities (such as news sliders, photos galleries/sliders, carousels, tabs menus)

When tracking mouse movement, you usually need to know the actual position of the mouse pointer. The event object that is passed to the handler contains some information about the mouse coordinates.
