Rubber Injection Compression Molding Machine

General Introduction
The rubber injection compression molding machine is specially designed for customers requiring mass production and small injection volume. It can manufacture a great many products at one time by utilizing a small quantity of raw materials, which greatly improves product properties and material utilization, increases production output and also effectively reduces the cost investment of customers.

Currently, this equipment is widely used for producing oil seals, O type rings and other sealing elements. Besides, with the advantages of fast high-temperature vulcanization, raw material saving and high automaticity, it gradually replaces the curing press in the rubber processing industry.

Design Innovation
Except the above mentioned advantages, the rubber injection compression molding machine is also novel in design.
1. There is a heating device inside the upper mould platen, which can promote the rubber vulcanization and shorten the cycle duration.
2. The upper mould plate is designed with several transfer injection runners for maximally saving the raw materials. Besides, each mould cavity comes with the same number of runners, thus the product uniformity is largely enhanced.

Rubber Injection Compression Molding Machine

Remarkable Features
1. This rubber injection compression molding machine can be used to manufacture small precision products without the runner waste or the cured rubber waste.
2. One-time feeding is sufficient for continuous injection and compression.
3. It enables evacuation, ejection and automatic control.



4. Injection and compression metering is accurate.
5. The temperature of heating platens is controlled within ±3°C.
6. The pressure for mould clamping and the integral running are stable.



7. The rubber injection compression molding machine is fitted with imported heating tubes and electric components.
8. It comes with the variable pump drive from Rexroth, high-pressure oil pipes and precise pipe joints.
