Functions of laboratory extruders
Feb 11, 2025| The main functions of laboratory extruders include extrusion, casting, film blowing, traction, trimming and winding of polymer materials. Specifically, laboratory extruders can complete these functions on a "desktop", which is suitable for polymer material casting and film blowing molding experiments, process parameter optimization, formula development, etc.
