Extrusion welders, blowers and heat guns from Leister are in demand worldwide and in use everywhere to thermally join or form plastics in apparatus and container construction. They impress with their welding consistency and process safety. Applications include 3D printing with an automated extruder on a robotic arm, construction and repair of aquaculture or hard plastic boats, inflatable boats, as well as ballast and fresh water tanks made from plastic membranes.

When tunnels or landfills are built, the quality of the welded seam is the top priority. This is because leaks would have fatal consequences for people and the environment. Geomembranes made of PE that are used for the seam must therefore be welded tight in the long term. Welding machines and hot air blowers from Leister are used for this.

Elastic floor coverings made of plastic, as well as natural materials such as linoleum and rubber, are practical and often installed in public spaces and private homes. With corresponding automatic floor welding machines from Leister, the joints in the sheets of the material can be sealed tightly. And for precise detail work, handy hot air blowers such as the TRIAC models or the SOLANO AT from Leister are ideal.

Technical textiles such as placards, tents and truck tarpaulins made of thermoplastic-coated fabrics can be processed and welded effortlessly with plastic welding machines from Leister. The welding seams look visually good and are long-lasting. They are also particularly dense because the material is not perforated as with sewing.

For sealing flat and pitched roofs, roofers from all over the world rely on proven Leister automatic welding machines. For example, the VARIMAT from Leister is suitable for overlap welding the plastic roof membranes on very large roof surfaces such as the flat roofs of industrial buildings. For medium-sized flat or pitched roofs, the smaller and handy lightweight UNIROOF semi-automatic welding machine is used.
