PLC Control of a Small Three-Layer co-Extrusion Film Blowing Machine For Laboratory Testing
Product introduce
Extrusion blown film refers to the process of continuously extruding plastic melt through a die at a certain temperature and shear force, and obtaining a double folded plastic film through compressed air expansion, wind ring cooling, and variable frequency traction.
