  • Patent number: 10518448
    Abstract: Additional injection modular system applicable in any process for molding parts or products by polymer injection is provided, wherein injecting one or more parts or products with a single material or a plurality of polymer materials requiring separate, simultaneous or sequential complementary injections becomes necessary in addition to the injection of a base material processed in a conventional injection machine. The system has a module configurable in both composition and dimension with optimized rheological and energy behavior which is installed between the closure assembly plates of the base machine and the mold, comprising a frame, front mold clamping plate, structure clamping plate, structure spacer blocks, at least one additional injection assembly, at least one additional injection nozzle and injection nozzle extension. The system herein can be used in the production of parts by injection processes generally designated as multi-component injection.

  • Publication number: 20170291340
    Abstract: The present application describes a modular unit for injection-compression molding (1). The modular unit for injection-compression molding (1) is arranged between the movable platen of the injection machine (21) and the stationary platen of the injection machine (22), in particular in the half-mold bearing face resulting from the division thereof by the opening joint. This modular unit for injection-compression molding (1) allows a substantial reduction of energy spent by reduction of inertial masses involved. The present application describes a modular unit for injection-compression molding (1) to be used in the production of pieces by injection being installed on any thermoplastic molding process.

  • Patent number: 7108501
    Abstract: The present invention refers to an Integrated Injection-Stretch-Blow Mold suitable for producing bi-orientated thermoplastics containers, which can be installed in an injection molding machine, occupying the space normally destined for injection molds. It consists of a central chassis (8) having in its interior a central block mechanism (30), with the injection cores (6cores (12) and the mechanisms for stretch and blow (9, 13, 23) and for release of the finish containers (18, 20); a motorized system (31), connected to the central block mechanism (30), by a rotating plate shaft (11), for the transport of the performs at least an injection mold (1) and a blow mold (14) placed around the central chassis (8).
