A screw injection system provides a specific amount of rubber into a closed, pressurised, mould.
The injection unit is fed by a supply of uncured rubber, which is maintained at room temperature to prevent premature curing.
Large components and components demanding more precision often benefit from being injection moulded. Injection moulding is usually used for multi-cavity moulds and is capable of producing many components per cycle.
Typical tolerances are in accordance with British Standards guidelines, although tighter tolerances can often be achieved by altering the flow of material within the mould. We frequently use mould flow simulation techniques to ascertain the optimum mould design.
