摘要： A method and apparatus for producing an injection moulded plastics article comprises introducing a supply of plastics material (20) into a mould space (13), supplying a first stream of pressurised fluid into the molten plastics material to form a fluid containing cavity (25) therein, maintaining fluid pressure in the cavity until the plastics material can sustain the form dictated by the mould surface. During the step of maintaining fluid pressure in the cavity, at least a portion of the first stream of pressurised fluid is vented or allowed to vent from the cavity, and simultaneously a second stream of pressurised fluid from a second source (26; 40; 41) is supplied to the cavity, which second stream replaces that portion of the first stream which has vented from the cavity.

摘要： A method for manufacturing a molded article comprises injecting a quantity of molding material sufficient for the preparation of the molded article into a cavity of a mold, injecting a first portion of fluid into the mold cavity, creating a gas channel within the molding material, and forming the molded article within the mold cavity. At least a portion of the first portion of fluid is exhausted through a gas port, a second portion of fluid is injected into the mold material, and the molded article is cooled within the mold cavity to a temperature beneath a softening point of the molding material.

摘要： A plastic tank comprises a line which is connected at least in certain sections to its wall and is formed in one piece with the plastic tank. For its production, the plastic tank is injection-moulded between a hollow mould and an inner mould inserted into the latter, the mould having a recess, in which a sprue body is formed as the starting material for the line. Before this sprue body can solidify completely, material is blown out from it by means of the internal gas pressure or pressure blowing technique via channels provided in the mould, so that the required line is created there. The lines may be arranged on the outside and/or inside and parallel and/or at an angle to the tank walls.

摘要： An apparatus for use in gas-assisted injection molding of plastic material so as to form an injection molded product includes a pair of mold members defining, when closed, a sealed cavity. A first opening is provided in one of the mold members for allowing the injection of a plastic material into the mold cavity and a second opening is provided in one of the mold members, and spaced from the first opening. A sleeve extends through the second opening. A probe extends through the sleeve and is adapted to be reciprocated therein from a retracted position to an extended position. The probe includes a first end adapted to selectively extend into the cavity, a second end and a longitudinally extending bore which terminates adjacent the second end. A reciprocating device is provided for reciprocating the probe in the sleeve held in the second opening of the one mold member in relation to the cavity.
