What Is Die Pressure in Plastic Extrusion Lines
Die pressure is the force exerted by molten polymer on the die exit. It controls material flow rate and shape retention. High pressure can cause swelling or distortion.

Learn about extruder types, components, and processing techniques for producing consistent plastic profiles and sheets.
