Leister Technologies AG presents new products at the K-messe

At this year's K-Messe, Leister will exhibit new welding equipment, automatic welding machines, air heaters and powerful infrared radiators for welding, joining and heating plastics. Experts from various Leister specialist units will demonstrate the devices and explain how they work. K-Messe visitors will be able to test the welding devices and automatic welding machines at the Leister stand.

Leister Plastic Fabrication, Roofing & Flooring (PRF) business line professionals have developed the UNIDRIVE 500, a new semi-automatic hot-air welder for sealing flat and pitched roofs. With its dual drive and a nozzle rotates from left to right, the UNIDRIVE 500 is especially suitable for welding close to the edge and where space is limited.

UNIPLAN 300 and UNIPLAN 500 are a new kind of automatic welder developed by the Leister Technical Textiles & Industrial Fabrics (TEX) business line and are used for overlap, seam and piping welding of advertising banners, tents and truck tarpaulins. The numbers 300 and 500 represent the two performance classes in which this automatic welder has been available since mid-August.

TWINNY T5 and TWINNY T7 are two new automatic welders developed by the Leister GEO (Geomembranes) business line. They have been designed for welding geomembranes ranging between 0.5 and 2.5 millimeters in thickness. The automatic welders are distinguished by their ease of use. Moreover, their large castors make them suitable for working on uneven surfaces. T5 and T7 stand for the two performance classes in which the automatic welder has been sold since mid-August.

Significant changes have recently occurred in the production of beverage cartons (Tetra Paks). The fossil fuels used to date are gradually being replaced by electricity generated from sustainable sources.

Leister takes this environmentally conscious trend into account and offers highly efficient electric hot-air systems for welding the longitudinal seam of beverage cartons. Also known as sealing units, these systems replace the gas burners previously used. Welding with hot air also offers another advantage: it prevents oxidation of polyethylene along the weld.

Powerful Krelus infrared radiators for industrial use

Krelus AG, part of the Leister Group since April 2018, has over 40 years of experience in the construction of customized infrared solutions. The Krelus infrared radiator transmits the heat directly to the product. The built-in film technology efficiently prevents heat loss at the back of the radiator so that cooling is not required. Furthermore, there is no need to heat glass or ceramics, so the radiator reacts very quickly. This offers many advantages: in addition to being able to accurately regulate the surface temperature of the product to be heated, rapid heating and cooling are a major plus. This allows the radiator to be switched off even during short production interruptions, saving energy and costs. Krelus will present its range of module radiators as well as customized infrared radiators at the K-Messe.
