Sprue Bushings

Sprue Bushings are an internal sprue component. They’re made of hardened steel and aid in accepting an extrusion nozzle. Sprue bushings offer the necessary opening for the molten plastic to be transferred into its respective mold cavity. These components contribute to a more rigid sprue and shorter cooling periods. Sprues must be sturdy because pickers and other industrial robots pick up molded pieces when ready for removal.
