摘要： A method for injecting plasticized masses such as rubber, silicone, and the like into a mold die of an injection-molding machine, directly or by way of a cold channel, uses a nozzle whose opening width can be changed. The opening width is maximal at the beginning of the injection process, and is changed over the course of the injection process, up to its end, using a predetermined control profile. The temperature of the mass is influenced in a targeted manner in accordance with the opening width, and the friction losses in the mass that change as a result of this.

摘要： An injection molding apparatus includes an injection piston that is slidable within a nozzle having a movable valve gate pin. The injection piston is movable from a retracted position to an extended position in order to force melt towards a mold cavity. A valve is located at a forward end of the piston to selectively block communication between a recess, which is provided in an outer wall of the piston adjacent the valve, and a melt chamber of the nozzle. Movement of the injection piston from the retracted position to the extended position causes the valve to close so that the predetermined volume of melt located below the valve is forced into the mold cavity, when the valve gate pin opens the mold gate.

摘要： A method and system for forming an injection molded plastic part. After the injection of plastic material has started, a volume of gas from a fixed volume reservoir is introduced into the plastic material at a low pressure forming a hollow cavity. The gas is introduced into the mold by a gas pin having a temperature sensing device, such as a thermocouple, positioned on it. The introduction of this volume of gas is initiated when the temperature of the plastic material in the mold has reached a predetermined value. After the mold is filled and packed with plastic, pressurized gas is introduced into the hollow cavity forming the completed plastic part.
