Description of welding method

The joining areas of the plastic pieces are pressed against an accordingly heated up element until enough material is melted.
The heating element is removed and the plastified surfaces of the plastic pieces are pressed together. The pieces cool down under pressure or way-limited until the melt is resolidified. Weld fillers are not needed.

Description of variants

Welding methods with standard temperature
The heating element temperature is in the range of the melting temperature of the plastic materials to be welded. The heating elements are normally anti-stick coated or covered. Thermoplastics with a melting point up to approx. 270°C can be processed.

Welding methods with high temperature
The heating element temperature is higher than the melting temperature of the plastic materials to be welded. The heating elements are normally not coated. Practically all thermoplastics can be processed independent from their melting point. Due to this method, there is a high emission of smoke.

Description of welding method

The ends of the plastic pieces are pushed into or over an accordingly heated up element until enough material is melted. The heating element is removed and the plastic pieces are pushed into each other at the plastified ends. The pieces cool down while sticking together until the melt is resolidified. Weld fillers are not needed.

Description of variants

Standard welding method without heated coil
The heating element temperature is in the range of the melting temperature of the plastic materials to be welded. The heating elements are normally anti-stick coated. Thermoplastics with a melting point up to approx. 270°C can be processed. The energy input is performed by means of heating element spigots and sockets.

Heated coil welding
Different thermoplastics can be processed depending on the availability of fittings. The energy input is performed by means of an integrated heated coil which is connected to an external source of current.

Description of welding method

The plastic pieces are fixed to each other at the joining areas.
The butt is melted with hot air until the surfaces are yielding under pressure.
The joint can be strengthened by means of a weld filler of the same plastic material.

Description of welding method

The plastic pieces are fixed to each other at the joining areas. The butt is melted with hot air until the pieces can be welded with additional material. The weld filler out of the same plastic material is melted in a barrel extruder, ejected and pressed into the preheated butt.

Description of welding method

The plastic pieces are positioned with the butts having a special distance to the accordingly heated up element until enough material is melted. The input of heat is performed contactless in form of infrared radiation and is for that reason not limited by the maximum temperature of an anti-stick coating. The heating element is removed and the plastified surfaces of the plastic pieces are pressed together. The pieces cool down under pressure or way-limited until the melt is resolidified. Weld fillers are not needed.

Description of welding method

The plastic pieces are fixed to each other and exposed to laser radiation. The input of heat is performed by the absorption of energy on the surface exposed to radiation. The plastic pieces cool down under pressure or way-limited until the melt is resolidified. Weld fillers are not needed.
