Best prepared.

Quality begins with pre-treatment. High-quality products require attention to detail. And that, right from the start.

This applies to the pre-treatment and cleaning of your products, but also to the selection of the plant manufacturer. Because in order to prepare your products optimally for further processing, a smooth interplay of the individual components within various process stages of surface technology is required – from pre-treatment to the final result. If you want it to be good, it's best to contact one of our specialists.

The L+F pre-treatment plant to measure

The pre-treatment is the basis for impeccable cleaning and degreasing of your workpieces' surfaces.

Even at this stage, you're laying the groundwork to achieve brilliant results when painting and powder coating. L+F has a clean solution for every task: industrial washing systems, spray degreasing systems, steaming cabins, immersion baths or ultrasonic systems. We adapt our systems to your individual needs: Should a continuous flow or a batch system be used? Should the system operate based on water or cold cleaner? What types of surfaces (aluminium, steel, plastic) do you treat and in what quantities? L+F's pre-treatment and cleaning systems are task-specific and therefore always individual.
