The screw is a long, helical-shaped shaft with deep grooves called flights wrapped around it. When it rotates, it moves material along its length. The barrel is a cylindrical housing that surrounds the screw. It's equipped with heating or cooling elements to control the temperature of the material being processed. Overall, the screw and barrel system enables precise control over the processing parameters, such as temperature, pressure, and flow rate, leading to consistent and high-quality output in plastic manufacturing processes.
