Resin moulding method and apparatus

In resin transfer moulding, each mould cavity is charged initially with a hot curing resin and subsequently with a cold curing resin. This results in a reduction of cycle time because the cold curing resin will be present in the mould near to the injection gate whilst the hot curing resin will flow...

This results in a reduction of cycle time because the cold curing resin will be present in the mould near to the injection gate whilst the hot curing resin will flow to the periphery of the mould.
