We deliver measurable result that improve the quality of molding components, increase production output and reduce molding process cost. Hot runner for Heavy Shot weight components: Molding for Heavy shot weight plastic components required large volume of melt delivery from the machine barrel to cavity. Hot Techs Hot runner technologies system for large parts feature Hot runner Manifold, Hot tip Nozzles and special gate opening designed for maximum melt flow that keeps the shearing force in the desired range. Pressure drop is minimized by shear force and melt viscosity inside the various sections of HR manifold channels and Hot tip Nozzles.
