Well prepared.

Quality begins with pre-treatment. High-quality products require quality down to the last detail. Right from the start.

This applies to the pretreatment and cleaning of your products, but also to the selection of the plant manufacturer. In order to prepare your products optimally for further processing, the individual components within the various process stages of surface technology must interact smoothly—from pretreatment to the final result. If you want to get it right, it's best to contact one of our specialists.

The customized L+F pretreatment system

Pre-treatment is the basis for flawless cleaning and degreasing of the surfaces of your workpieces. 

At this stage, you are already laying the foundation for achieving brilliant results in painting and powder coating. L+F has a clean solution for every task: industrial washing systems, spray degreasing systems, exhaust air cabinets, immersion baths, or ultrasonic systems. We tailor our systems to your individual needs: Should a continuous or batch system be used? Should the system be based on water or cold cleaner? What types of surfaces (aluminum, steel, plastic) do you treat and in what quantities? L+F's pretreatment and cleaning systems are task-specific and therefore always customized.
