Types of Plastic Welding

Hot-Air Welding

HAND TOOLS, AUTOMATIC WELDERS, STATIONARY WELDING MACHINES – Successful hot air welding requires three key elements: temperature, time and pressure.

Hot-Wedge Welding

COMBI WEDGE WELDERS – With combi-wedge welding, preheating takes place via hot air and the actual welding process with the hot wedge. Preheating also partially cleans the material to be welded.

Combi-Wedge Welding

Hand tools, automatic welders, stationary welding machines.
Successful hot air welding requires three key elements: temperature, speed and pressure.

Pendulum Welding

HAND TOOLS – The welding rod and the base material are heated with hot air using an up and down, pendulum-like motion and consistent downward pressure.

Draw Welding (Speed Welding)

HAND TOOLS – By using a speed welding nozzle, the welding rod and base material are plasticized by hot air and joined under consistent contact pressure.

Extrusion Welding

HAND EXTRUDERS – The base material is preheated by hot air. The welding rod is fed into a heater barrel and processed by the extruder screw.

Low Voltage, Hot Wedge Welding

HOT WEDGE WELDERS – In low-voltage, hot wedge welding, a thin metal plate (wedge) is heated by controlled electrical current.
