Extrusion Blow Molding: How Hollow Plastic Parts Are Formed for Industrial, Automotive, and Commercial Applications

Extrusion blow molding is the most widely used process for producing hollow plastic parts across industrial, automotive, agricultural, and consumer markets. The process uses a plasticating extruder to produce a continuous tube of molten thermoplastic — the parison — which is captured by a split mold, inflated with pressurized air, cooled against the mold walls, […]
