Injection molding is a critical process in the manufacturing industry, enabling mass production of high-quality plastic and metal components. Among the essential components of this process are the sprue bush and diffuser , which play crucial roles in ensuring smooth material flow and minimizing defects. In this blog, we will explore their functions, benefits, and importance in molding operations. What is a Sprue Bush? A sprue bush is a crucial component in the injection molding process that serves as the entry point for molten material into the mold cavity. It is typically made of hardened steel and designed to withstand high temperatures and pressures. Functions of a Sprue Bush: Guides the molten material from the injection nozzle to the mold. Reduces material wastage by ensuring a smooth flow. Prevents leakage and minimizes air entrapment. Enhances mold longevity by reducing wear and tear. What is a Diffuser? A diffuser is a component that helps evenly distribute the mo...
