ABSTRACT:
An injection moulding machine used in conjunction with a closed split mould, has its shot volume controlled by a device which responds to widening of the mould parting line occurring when the mould is completely filled with moulding material as a result of the pressure build up which occurs inside the mould. Contactless sensing of widening of the parting line is described, by means of electromagnetic sensing devices. The shot volume can thus be held at the optimum value at which minimum flash occurs and complete filling of the mould is assured.
