Hot air hand tools from Leister is primarily used for welding, plastic fabrication, shrinking plastics, shrinking cable connections, heating and forming, deburring plastic parts, shrinking of pallets and bulk goods, etc. These high quality products are made in Switzerland with the best in class technology and precision that will deliver beyond your expectations.

BEST EXTRUSION WELDERS

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.

Civil engineering applications

SAFE AND ERGONOMIC WELDING OF PLASTIC MEMBRANES WITH LEISTER

In civil engineering, tunneling, and disposal applications, the quality of the sealing system is the top priority. Any leaks can have fatal consequences. Therefore, it is incredibly important that the processing quality fulfills extremely stringent requirements. Not only the material itself and the processor are responsible for this – in large part, so is the tool used to carry out the work. Leister tools not only facilitate incredibly precise welding, they also stand out from the crowd thanks to their ergonomics. They can be relied on, no matter where in the world they are used.

TECHNICAL TEXTILES & INDUSTRIAL FABRICS

It is impossible to imagine life today without billboards or industrial fabrics. Whether it is classic billboards on buildings or at events, tents, covers, tarpaulins, architectural structures or sunblinds: it is always a product which was more than likely welded with Leister tools. Leister has always been at home in this important market and boasts unique know-how accordingly. The development of new tools is a top priority for Leister in this application area too. Alongside welding machines, hand welding tools from Leister are utilized here as well, together with matching nozzles and Leister's legendary pressure rollers. Hem welding, seam welding, pocket welding or rope welding, nothing is complicated for Leister.

Electrofusion Welding is a method of joining HDPE and other plastic pipes using special fittings that have built-in electric heating elements which are used to weld the joint together. The pipes to be joined are cleaned, inserted into the electrofusion fitting and a voltage is applied for a fixed time depending on the fitting in use. The built in heater coils then melt the inside of the fitting and the outside of the pipe wall, which weld together producing a very strong homogeneous joint. The assembly is then left to cool for a specified time. Welding heat and time depends on the type and size of the fitting.

Some features are:

• Output depending on your needs up to approx. 3 kg/h
• On both sides easy to insert welding rods (3 and 4mm) for flexible welding positions
• Locking button for continuous extrusion welding with little effort
• Quickly replaceable welding shoes result in high productivity
• Turnable handle for high ergonomics
