INJECTION COMPRESSION MOULDING APPARATUS

摘要

An injection compression moulding apparatus comprises two mould parts (32, 36) which define a mould cavity and are mounted on two relatively movable platens (40) of an injection moulding press. An actuator (44) is arranged in series with the platen 40 acting on at least one of the mould parts (36) and is controlled in synchronism with the movement of the platens to enable the relative speed of the two mould parts (32, 36) during a mould closing phase of each article moulding cycle to be modified, the speed of relative movement of the mould parts being the vector sum of the speeds of movement and the platens (40) and the actuator (44).
