Working
Strips of rubber are fed into the worm barrel which transfers the rubber into the injection cavity which is already at a higher temperature, then a present quantity of rubber is injected into the mould, where vulcanization takes place.

Advantage Compared to Conventional Press Machines
» Due to the Injection process the cycle time is reduced considerably ,almost by 50% .
» Wastage and rejections are controlled as compared to conventional press system.
» Injection process results in burr free finish as a present quantity of rubber is injected.
» Opening of the mould is automatic as compared to conventional press in which mould is taken out and then manually opened.

Clamping Unit
The machine uses high efficiency direct ram clamping system to ensure burr free product. No need for mould height adjustment due to Hydraulic Clamping. Each station is equipped with P.I.D temperature controllers to ensure accurate heating and consistent product quality. Long mould opening ensures easy retrieving of finished product.

Injection Unit
It uses specially designed screw barrel in which strips of rubber can be fed. Screw barrel are made from EN- 41B nitriding alloy steel and are engineered on imported milling and boring machines to ensure high productivity for years to come.

The injection unit is equipped with 3 stage P.I.D temperature controllers to ensure fast and accurate heating .As the rubber is already at a higher temperature when injected into the mould, the cycle time is reduced considerably almost by 50%.

Control Unit
It uses PLC control systems for full automation with display unit.Premium quality electrical parts are used to give optimum results.
