Blow Molding Screw & Barrel – High Performance Extrusion System
The Blow Molding Screw & Barrel is the most critical component in blow molding machines, responsible for plasticizing, mixing, and delivering material with consistent melt quality. It directly affects production efficiency, cycle time, and final product quality.
All processing begins in the extruder, where proper temperature control and uniform mixing are essential to achieve high-quality parison formation. A well-designed screw ensures stable output and reduces processing defects in final molded products.
