UV curing for maximum efficiency in coil coating

UV systems for processing coils

Coil coating is a continuous process in which metal strips such as steel, aluminium, stainless steel or wires are coated and then cured. For this demanding process, we supply specially developed UV drying systems (UV systems) that are optimally tailored to the requirements of the coil coating industry.

Our portfolio includes state-of-the-art technologies such as LED UV, UV and excimer systems, which have been specially developed for curing pre-coated thin sheet metal products. These innovative technologies are not only efficient, but also particularly environmentally friendly – thanks to the use of solvent-free 100% systems or water-based coating systems. This complies with the requirements of the VOC Directive and makes their use particularly sustainable. In addition, the low energy consumption significantly reduces operating costs, making UV technology a sustainable and economical solution.

UV curing systems for industrial applications and converting

Compared to conventional drying ovens for water-based coatings, UV drying offers numerous advantages:

  • Extremely short drying and processing times
  • Significantly lower energy consumption and a compact design that takes up 80–90% less space.
  • Our UV systems can be easily integrated into existing galvanising lines – and enable efficient in-line coating
  • The UV systems can be switched on and off at short notice
  • No thermal afterburning necessary – the coater room does not need to be ventilated or deaerated, and there is no need for an evaporation section.
  • The UV systems can be switched on and off at short notice.
  • Rapid, relatively cool curing of coatings and primers enables significantly smaller coolers or a shorter cooling section for recooling the coil.

Substrates and applications

Our specially developed UV systems are ideal for coating stainless steel coils, steel coils, galvanised steel and wires. Typical applications include the curing of primers and top coatings, which provide reliable scratch protection, effective corrosion protection and durable anti-fingerprint surfaces. UV coatings are characterised by their exceptional resistance to scratches, chemicals and weathering. The UV curing process can also be carried out under inertised conditions with nitrogen to achieve the best results in quality and performance.

Special features and industry expertise

Robust steel wires are integrated to protect the UV lamps and reliably prevent damage. In addition, the UV dryers are designed so that they can be moved apart. This ensures optimum accessibility for maintenance work, servicing or in the event of a coil tear.

Thanks to our advanced UV technology, you benefit from fast production processes and highly efficient UV systems. The excellent UV efficiency of our UV systems not only contributes to significant energy savings, but also to easy integration into new or existing production lines thanks to their compact design. With our extensive expertise in the metalworking industry, we develop customised solutions that are perfectly tailored to your requirements and can be integrated into your production machines.
