Leister Hand Extruders
Leister pioneered the first hot air tool in 1954. Almost 60 years later they are still market leaders in technology innovation and production quality. All Leister hot air tools are manufactured in Switzerland and meet strict international standards and directives.

The Leister extruder range covers the full spectrum of extrusion welding applications. The smallest tool, the WELDMAX, is suited for small fabrication and repair (e.g. spigot welding), while the WELDPLAST S6 puts out a massive 6.0kg/hr of extrudate, making it ideal for large scale liner welding.
