  • Patent number: 8142184
    Abstract: Tools of plastics processing machines are cooled over their surface and/or at particular points as soon as compound supply is finished. Heat is thus suitably withdrawn from the shaped compound, ensuring the fastest possible cooling and shortening cycle times. The invention relates to a closed, coolant-filled cooling system for tools of plastics processing machines having at least one compressor, a supply pipe, a tool region to be cooled and a discharge pipe, the supply pipe being connected to the outlet of the compressor and the discharge pipe being connected to the inlet of the compressor, while at least one open end of the supply pipe plunges into at least one bore arranged in the tool region to be cooled, and an open end of the discharge pipe is sealed to this bore. The supply pipe and the discharge pipe may be combined in a coaxial pipe with the supply pipe arranged in the centre and the discharge pipe enveloping the supply pipe.

  • Patent number: 7887320
    Abstract: An auxiliary device and a method for finishing and calibrating preforms that are removed from a multiple tool in an unstable shape, the calibration process being performed with compressed air immediately after removing and withdrawing the preforms from the multiple tool. Nipples that can be inserted into the preforms are provided with expandable press rings or sealing rings in order to seal the interior of the blow-molded part of the preforms. The compressed air is introduced via the nipples, the sealing process being performed by radially expanding the press rings or sealing rings in analogy to the closing process of thermoses, thus protecting the preforms from adverse forces. The sealing point can be randomly selected in the transition zone from the threaded part to the blow-molded part of the preforms. The interior of the blow-molded part is optimally sealed without affecting the form stability and dimensional stability of the preforms.

  • Patent number: 7887742
    Abstract: The process and the apparatus serve for the blow moulding of containers (2). A parison (1) composed of a thermoplastic material is first subjected to heat conditioning along a transport path in the region of a heating section (30). The parison is then subjected to a forming process within a blow mould with exposure to blowing pressure to give heat container. The heat conditioning of the parisons is carried out by a plurality of mutually superposed radiant heaters (41). The blow moulding of the container is followed by wall-thickness measurement at at least one level within the height of the container. The heating power of a radiant heater associated with this height level is controlled. The control system receives a prescribed wall-thickness value as required value and the measured wall thickness as actual value.

  • Publication number: 20110031659
    Abstract: A method and apparatus for stretch blow moulding a preform into a desired article is disclosed. The method includes the steps of inserting the preform into a hollow mould, stretching the heated preform with a stretching member, filling the preform with an incompressible fluid such that the preform expands and is formed into the article by the mould and draining the incompressible fluid from the interior of the formed article. The apparatus comprises a hollow mould for receiving the preform, a stretching member for stretching the preform, an incompressible fluid filling means for filling the preform with an incompressible fluid such that the preform expands and a drain for draining the incompressible fluid from the formed article.
