    摘要: Provided is an injection molding machine in which variation in the quality of a molding product is reduced. An injection molding machine includes: a mold clamping unit (10) which performs mold closing, mold clamping, and mold opening of a mold unit (30); an injection unit (40) which injects a molding material into the mold unit (30); a controller (90) which controls the mold clamping unit (10) and the injection unit (40); and a distortion detector which detects a distortion of the mold unit (30) due to a pressure of the molding material which is filled into the mold unit (30), in which the controller (90) controls the injection unit (40), based on the detection value of the distortion detector.

    摘要: A process and apparatus for plastics injection moulding comprises injecting a quantity of molten plastics material into a mould cavity (30) and injecting pressurised gas (52) or pressurised liquid into the plastics material in the mould cavity. After holding the pressure of the gas or liquid on the plastics material in the mould cavity for a period of time in order to apply a packing pressure to the plastics material, a portion of the molten plastics material is expelled into one or more secondary cavities (32) or expelled back into the barrel (22) of the injection moulding machine. The step of injecting the plastics material may be effected with or without packing of the plastics material prior to the injection of the pressurised gas or liquid.
