Video Description:
This video explains the critical relationship between temperature changes and thermal expansion in twin-screw extruder barrels made from 304 stainless steel. You'll see a clear, step-by-step demonstration of how just a 1°C temperature rise causes approximately 17 microns of expansion per meter of barrel length. We'll explore the practical implications of this thermal behavior for manufacturing precision, equipment performance, and maintenance planning in industrial extrusion processes.
