    Abstract: A pivot casting component used in an apparatus for extrusion blow molding polyethylene teraphthalate (“PET”) is disclosed. The pivot casting is designed to provide increased strength and increased reliability over prior components with the blow mold clamping linkage system. Prior art pivot elements were designed and fabricated from separate elements such that weak points, and stress concentration points were created. Such weak points resulted in the pivot element being a weak component in the blow mold clamping linkage system. The inventive pivot casting is cast as a single component from higher strength materials, with an improved geometry to increase component strength, durability and overall system reliability. In a preferred embodiment, the air side pivot casting is formed from 80-55-06 ductile iron resulting in a 40% increase in tensile strength over prior pivot components.

  • Patent number: 8790111
    Abstract: The device according to the invention is used to blow-mold containers. After thermal conditioning, a preform is shaped into the container inside a blow mold by the effect of blowing pressure. The blow mold is retained by a support. A pressure area (43) is sealed from the surroundings by a seal (41). The seal (41) has at least two areas (45, 46). A first area (45) is composed of a harder material than the second area (46). The two areas are rigidly connected to each other.

  • Publication number: 20140178522
    Abstract: The invention relates to a method for producing hollow bodies from thermoplastic material, comprising the molding of at least two sheet-like, web-shaped preforms of plasticated thermoplastic material in a multi-part tool forming a cavity to form two complementary shells, and also the joining together of the shells to form a substantially closed hollow body, wherein the preforms are brought between open parts of the tool which each have part-cavities, the parts of the tool are then closed against a tool separator arranged between the preforms, and the preforms are inserted into the part-cavities with the use of differential pressure and molded. In a subsequent separate method step, the tools are reopened and internal components of the hollow body to be produced are fastened to the shells. Finally, the shells are joined together by reclosing the tools to form a closed hollow body.

  • Publication number: 20140161920
    Abstract: What is described is a blow-molding machine for plastic containers, comprising a plurality of platens for supporting blow mold halves, wherein at least two of the platens are in the form of movable multi-carriers for simultaneously supporting at least two blow mold halves which are assigned to different blow-molding cavities. Since the multi-carriers are driven in such a manner that at least one of the blow-molding cavities can be opened and at the same time at least one other of the blow-molding cavities can be closed by means of a continuous movement of the multi-carriers, acceleration and deceleration ramps can be reduced upon opening and closing and it is possible to gain process time for the blow molding.
