Hot Runners

For runner-less, high cycle, low cost production

Hot runner injection molding have the heated and fluidized runner within the mold heater. Not only does it reduce wasted and loss by being runner-less, it increases molding efficiency and makes high precision molding easy under high pressure.

  • ・Customized designing available to meet your needs
  • ・Molds have a simple construction and long life
  • ・Runner-less system reduces waste and loss of plastic
  • ・Minimum pitch between gates: 17.5mm
  • ・Effective against warpage of product
  • ・Available for both engineering plastic and super engineering plastic
  • ・Available to be mounted on up to 30 ton molding machines
