Plastic welding with Leister With plastic welding, workpieces made of thermoplastic are joined inseparably to one another using a combination of thermal energy and pressure. Central factors are welding speed and the length of the welding process. Plastic welding is used in many areas: For the processing of tarpaulins and plastic sealing sheets, on the roof, in earthworks, hydraulic engineering or tunnel construction, for floor coverings, in vehicle repairs and in equipment construction.

Thermoplastics are being used more and more for storing a huge range of liquids or for manufacturing what can be complex process equipment, such as fans or pumps. Plastic's resistance to corrosion and material strength are usually the reasons why it is used. In addition, the price of a part made from plastic is lower than that of one made from metallic materials. Leister offers a full range of hand extruders, hand welding tools with integrated blowers, hand tools operated with an external fan (together with matching blowers), and a variety of nozzles for this application area.
