Single Color EVA Foam Injection Machine

Introduction

Single color EVA foam injection machine is equipped with two full-automatically efficient injectors, high-performance mould clamping system and PC control system. Using EVA as raw material, the injection moulding machine can produce soles and various kinds of EVA foaming products.

Features

1. Injection System
With a potentiometer, it can calculate material quantity accurately in PLC and PC systems.
Single color EVA foam injection machine applies linear rails and the motor drive which realizes immediate braking function to promise rapid movement of infectors. The location machine can measure the accurate location with rotary encoder.
2. Mould Closing System
One color EVA injection moulding machine works rapidly in mould-opening and mould-closing procedures and its mould closing system is assured to proceed in a hermetic unit. It is designed in low operation height to provide extra height for mould opening, making it flexible to use different moulds.
3. Controlling System
Single color EVA foam injection machine applies human-computer interaction interface and touch screen on basis of windows operation system. It realizes real-time controlling in material rotate speed, injection quantity, infection time, injection temperature, sulfuring time and productivity. In PLC and PC controlling system, the machine is functionally clear and operationally easy.
4. Oil Hydraulic System
This machine applies proportional control valve to control oil pressure and flow.
5. Others
According to ergonomics, single color EVA foam injection machine is designed in low operation height. Apart from this, mould thickness adjusting is stepless to accommodate moulds in thickness of 100-260 mm. It uses a unique way to produce rubber material or EVA material.

Advantages

1. Mould closing system of EVA injection moulding machine is designed in rapid open-close way and drove by hydropneumatic power. The injection moulding machine has four oil cylinders to equilibrate itself. Pressure for working can reach to 200 T.
2. With net-based management, single color EVA foam injection machine can be controlled long-distantly. Through industrial PC and PLC, whole controlling system displays powerfully in production.
3. Highly responsive proportional control valve is applied in injection system. Injectable fuel-pump is used to keep high accuracy (2 ‰ ±) to promise high quality and efficiency.
4. For high anti-jamming capacity, long-distance digital module is used to control temperature system of the single color EVA foam injection machine. High accuracy (0.3 ±) reduces size deviation caused by temperature-control failure.
5. There are two moulds in every workstation, and the two moulds work independently without affecting each other. Besides, they can be interchanged to increase productivity in flexible ways.

Single color EVA foam injection machine and disc feeder of Jili Co. are controlled through certain pressure proportion. Disc Feeder has various moulds which inject material in the given pressure by control panel, thus it can produce many kinds of items with different materials of various quantities. Linear rails are applied in one color EVA injection moulding machine to promise rapid movement of injectors during operation.
