  • Patent number: 9211668
    Abstract: A system and method for post-treatment of a hollow body molding produced in an injection molding mold. A receiving finger is provided with a first end and a second end. The receiving finger is designed that it can engage into the hollow body molding. The outside shape of the receiving finger substantially corresponds to inside shape of the hollow body molding so that the receiving finger (5) can hold the hollow body molding. Preferably, the outside diameter of the receiving finger is substantially equal to inside diameter of the hollow body molding in a cooled condition so that the hollow body molding can be removed from the receiving finger even after shrinkage. Desirably, the outside diameter of the receiving finger is between about 0.01 mm and about 1 mm and preferably about 0.1 to about 0.5 mm smaller than the inside diameter of the hollow body preform in the removal condition so that the hollow body molding can be removed from the receiving finger even after shrinkage.

  • Patent number: 8025500
    Abstract: The present invention concerns a transfer element (1, 9) for an injection molding system comprising a flow lumen for a plasticised plastic material. To provide a transfer element for an injection molding system, which makes it possible to further increase the material throughput of the injection molding system without having to tolerate increased wear of seals and other system components, it is proposed in accordance with the invention that it has a device for degassing of the flow lumen.
