  • Retrofit module for adding a plasticizing and injection unit to an injection molding machine, and injection molding machine with added retrofit module
    Publication number: 20060078645
    Abstract: A retrofit module for attachment to an injection molding machine having a plasticizing and injection unit includes a module plasticizing and injection unit, and a support assembly to secure the module plasticizing and injection unit on the injection molding machine independently from the plasticizing and injection unit of the injection molding machine. The module plasticizing and injection unit and the plasticizing and injection unit of the injection molding machine define hereby length axes which extend at an angle of less than 90°. Extending through a nozzle orifice of a platen of the injection molding machine is a nozzle assembly for conducting melt produced by the plasticizing and injection unit of the injection molding machine and the module plasticizing and injection unit. The nozzle assembly is constructed to allow docking of the module plasticizing and injection unit and plasticizing and injection unit of the injection molding machine.
