What is the gap between screw and barrel?

This small gap ensures that there's proper compression and sealing of the material being processed, preventing leaks and maximizing efficiency. If the gap is too large, it can lead to material leakage, degradation of product quality, and decreased efficiency in the extrusion process. Conversely, if the gap is too small, it can cause excessive wear on the screw and barrel surfaces. Adjusting and maintaining this gap is essential for achieving optimal performance in extrusion processes.
