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 method (300) is provided for controlling an injection unit (100) having a first sub-assembly and a second sub-assembly, first and second sub-assemblies being functionally identical units. The method (300) includes the steps of appreciating an operational parameter for each of the first and second sub-assemblies, appreciating a target set point (146) associated with operating each of the first and second sub-assemblies, and when the operational parameter for at least one of the first and second sub=assemblies differs from the target set point (146), adjusting the operation of the at least one sub-assembly towards the target set point (146) by a control action. The adaptive control regulator (148) is operable to modify the control law of one of the first and second sub-assemblies so that the first and second sub-assemblies have substantially equal performance.

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.

摘要: A process of forming molded articles using an injection molding apparatus is provided. The process includes providing a thermoplastic material to the injection molding apparatus. The thermoplastic material is heated such that the thermoplastic material is in a molten state. The molten thermoplastic material is injected into at least one mold cavity of the injection molding apparatus using an injection element. Melt pressure of the thermoplastic material filling the at least one mold cavity is monitored using a sensor. The sensor provides a signal indicative of melt pressure to a controller. The controller controls introduction of a non-reactive additive to the thermoplastic material thereby changing a viscosity of the molten thermoplastic material based on the signal. A molded article is formed by reducing a mold temperature of the thermoplastic material within the at least one mold cavity.
