# Core Business Divisions and Technological Focus
Leister Process Technologies' comprehensive portfolio is structured around three primary pillars of advanced technology, plus the related microsystems unit, Axetris.
# 1. Plastic Welding Technology
Leister is the unequivocal market leader in equipment for welding thermoplastic polymers. This division focuses on providing hand tools and automatic machines for joining plastics in construction, commercial, and industrial settings.
Products & Services:
* Automatic Welding Machines: These are high-performance machines for welding large-scale plastic sheets and membranes, such as the VARIMAT series for roofing and the GEO series for civil engineering applications. They are designed for high-speed, consistent welding of materials like PVC, TPO, and other technical textiles.
* Hot-Air Hand Tools: Hand-held devices like the TRIAC series are versatile tools for professional plastic fabrication, detailed welding work, roofing membrane repairs, and shrinking applications.
* Extrusion Welders: Specialized hand-held and automatic machines like the FUSION series that use a plastic granulate or rod to create thick, high-strength welding seams on materials used in tank construction, pipe fabrication, and lining systems.
* Hot-Wedge Welders: Equipment used specifically for welding geomembranes in civil engineering projects like tunneling, landfills, and water conservation.
* Brands: Products are distributed under the LEISTER brand for professional-grade, Swiss-made equipment, and the WELDY brand, which focuses on functional devices for certain applications and private label customers.
Key Application Areas:
* Roofing (welding single-ply membranes)
* Flooring (welding seams of plastic floor coverings)
* Civil Engineering (welding geomembranes in tunnels, landfills, and water reservoirs)
* Plastic Fabrication (welding plastic tanks, pipes, and sign materials).
# 2. Industrial Process Heat
This division focuses on providing reliable, controllable, and powerful hot-air and infrared systems for integration into industrial production lines and machines.
Products & Services:
* Hot-Air Blowers and Heaters: Industrial-grade components (e.g., HOTWIND, MISTRAL, LHS series) used as heat sources in manufacturing processes. They supply a precisely controlled stream of hot air for drying, heating, shrinking, and sterilization.
* Infrared Systems: Following the acquisition of Krelus AG, the portfolio was expanded to include powerful infrared systems (KRELUS brand). These systems are used for contact-free, efficient heating of materials across various industrial sectors.
* Blowers and Accessories: Complementary devices to supply the necessary airflow for hot-air heating systems, including ignition blowers (IGNITER) and various fan types.
Key Application Areas:
* Drying processes (paper, textiles, nonwoven materials, metals).
* Shrinking films in packaging technology and electrical engineering.
* Thermal applications in mechanical engineering and automated production systems.
* Food-related processes (e.g., roasting, drying fruits).
# 3. Laser Plastic Welding Systems
This high-tech division specializes in non-contact laser systems for high-precision, hermetic joining of thermoplastic components.
Products & Services:
* Laser Welding Systems: Systems like the NOVOLAS series for sequential (e.g., Modulas C) or simultaneous (e.g., Modulas S) laser transmission welding. These are used to create invisible, high-strength welds.
* Micro-Technology Applications: The systems are capable of handling micro-applications such as welding small components for medical devices, sensors, and micro-fluidic chips.
Key Application Areas:
* Automotive industry (welding headlights, sensors, fittings, and tanks).
* Electronics (welding housings, electronic keys, and plugs).
* Medical technology and packaging where high-precision and hermetic seals are critical.
# 4. Microsystems (Axetris AG)
Though a separate entity within the Leister Group, Axetris AG develops and produces high-precision micro-technical components that leverage Leister's technological expertise.
Products & Services:
* Gas Sensor Modules and Systems: Products based on MEMS (Micro-Electro-Mechanical Systems) technology for gas sensing applications.
* Micro-Optical Components: High-precision components for industrial and communication applications, often manufactured in dedicated cleanroom facilities.
# Value-Added Services
Beyond equipment and components, Leister Process Technologies offers a suite of support services to ensure optimal customer outcomes:
* Industrial Consulting: Expert advice on integrating Leister technology into complex production processes.
* Application Lab Services: Customers can utilize in-house laboratories for material testing, feasibility studies, and process optimization to develop specialized welding and heating solutions.
* Maintenance and Repair: A global network of service centers ensures accessibility to spare parts and expert product maintenance.
* Digital Solutions: Provision of various digital tools and interfaces for machine integration, monitoring, and quality assurance.
In summary, Leister Process Technologies is a robust Swiss-based technology powerhouse whose principal function is the design, development, and manufacturing of world-leading equipment for processing plastics and providing industrial process heat, underpinned by advanced laser and microsystems technology.
