Single Color EVA Foam Injection Molding Machine

The single color EVA foam injection molding machine is equipped with two full automatic and high-efficiency injectors, combined with high-performance mould clamping system and PC control system. Using EVA as the raw material, the injection molding machine can produce midsoles, soles and various kinds of EVA foaming products.

1. Injection system of Injection Molding Machine
The measuring mechanism which uses potentiometer detection, along with PLC and PC, can compute and control material quantity precisely. The two injectors of the EVA foam injection molding machine utilize the worm gear reducer and the brake motor, running at a high speed controlled by a converter. The orientation system, using ultrasonic linear transducer, provides high accuracy.

2. Mould clamping system of Injection Molding Machine
The two-step mould opening/clamping mechanism comes with a detection device for full mould opening. Large mould design, with high compatibility, enables the flexible use of a variety of moulds.

3. Computer-control system of Injection Molding Machine
The PLC control module works through a graphic display interface to show all monitoring information and setting conditions: material input amount, injection temperature, mould temperature, operation time, output, mould data, etc. All operation processes can be controlled and performed on the touch screen. Besides, the operation instructions are easy to be learned. With the man-machine interface, maintenance and malfunction detection of the single color EVA foam injection molding machine becomes easy and time saving. Multistage code control enables settings for different management levels from operators, maintenance men to managers, which can avoid man-made negligence and keep production information safe.

4. Hydraulic system (Oil pressure system) of Injection Molding Machine
The use of proportional control valve together with the computer control system enables the hydraulic system of the injection molding machine to accurately keep control of the flow of multistage pressure and speed. Pumps are designed to keep noise down and improve efficiency.
