Processing polymers such as PFA/FEP by injection moulding is extremely critical as the process requires close monitoring with controlled heating & cooling of assemblies during the entire moulding stage.
This process at Horizon takes place in its very own fully equipped in-house manufacturing facility. It houses a semi-automatic special purpose injection moulding machine which is used for pre-heating and lining cast housings. The machine has a transfer system in which injection and transfer of plasticised material is done through an isothermal process. The facility is a one of its kind in India having its own advantages over the conventional lining method which uses transfer moulded system.
The design for tooling assembly ensures that mandrels are centrally located when assembled inside the cast housing and maintain this position through the entire moulding stage. This ensures uniform lining thickness of every fitting/cast body and zero residual stress. The lining technique also ensures that the liner fits closely inside the cast housing which is very important for high vacuum ratings.
