Extruders From Leister

Leister introduced a completely new line of handheld extruders to the market at K 2004 in Düsseldorf, Germany. Many technical refinements never before implemented for hand extruders are concealed under the solid housing.

The cooling system makes overheating a thing of the past. The brushless motor in the hot air unit means it is maintenancefree. The top of the line model WELDPLAST EC 4.0 (above) uses two brushless motors: one beside the hot air unit, the other for the extruder screw.

Leister placed great importance on user-friendly handling in the development of its new handheld extruders. Their compact construction ensures quiet operation and hence a new quality of working. The devices are also comfortable to hold due to their optimal weight distribution. All the WELDPLAST models offer a state-of-the art display suitable for construction site conditions. The hot air supply can be conveniently refitted, allowing for welding in the opposite direction. Even the handle can be rotated – much to the joy of lefthanders. The double-sided, twist-free welding rod feed avoids problems associated with unrolling welding rod.

Extrusion rates vary between 4 and 6 kg/h for the WELDPLAST models. A version for civil engineering is also available - the WELDPLAST G6.0 – with granulate funnel and another for process equipment manufacture – the WELDPLAST A4.0 – a device for use with an external air supply. Leister rounds off its broad range with the smaller models FUSION 3.8 and WELDMAX.
