Screw Barrel

A screw barrel is a critical component in extrusion and injection molding processes, consisting of a cylindrical barrel that houses a rotating screw. This assembly is designed to transport, melt, and mix raw materials, typically plastics, before they are shaped into final products.Screw barrels can be customized for different materials, including thermoplastics and thermosets, making them versatile for various applications.

The screw features a specific design that includes flights and channels, facilitating efficient movement and ensuring proper melting and homogenization of materials. Heating elements along the barrel maintain optimal temperatures, allowing for precise control during the melting process. The rotation of the screw generates pressure, helping to force the molten material through the die for shaping.
