Sprue bush / List of 2 manufacturers
What is a Sprue bush?
A sprue bushing is a critical component in plastic injection molding, used to channel molten resin from the injection molding machine into the mold. It is installed on the fixed side of the mold and ensures smooth flow of resin into the mold cavity. Sprue bushings are designed to withstand high temperatures and pressures and are typically made from hardened steel or specialized alloys. This component prevents resin leakage and is essential for efficient and stable molding processes. Its design also affects resin flow and the quality of the final product.
