Extrusion welding

Extrusion welding machines use a heated barrel with a plasticating screw to deliver molten plastic to a specially shaped shoe. The shoe is shaped to make a bead of plastic suitable for the material type and thickness being welded.

A hot air blower is attached to the extrusion welder to preheat the weld area. The welder uses its own weight to create the pressure required for welding and the operator steers the welder manually. Extrusion welders come in a number of sizes with different output rates.
