Extrusion Blow Molding

Hollow Bodies from the Blow Mold

More Information on the Blow Extrusion Process

Our regranulates are ideal for applications that are produced using the extrusion blow molding process.

The extrusion blow molding process is a production process used to manufacture hollow bodies from thermoplastics. The molten polymer is pressed through the die via a screw conveyor to produce a tubular preform (extrusion). This is transferred to a blow mold and adapted to the inner contours of the mold by internal pressure (blow molding). A typical distinguishing feature of extrusion blow-molded packaging is a pinch seam on the underside.

The most common plastic products made by blow extrusion include

  • Bottles
  • canisters
  • barrels

High Density Polyethylene HDPE

High Density Polyethylene (HDPE) is a thermoplastic material. It is characterized by its high density, strength and rigidity. HDPE is often used for packaging, pipes, hollow bodies and containers as it is resistant to chemicals and UV radiation.
