Reducing Cleaning Costs by More than Two Thirds

Doris Schulz

The cleaning systems used on modern engine and gearbox production lines in the automotive industry have the highest specific energy consumption of all the machines on the line. This is a very good reason for considering a more efficient approach to cleaning. PDF-Download

Is NMP Still Needed in Coating Removers?

Dr. Jürgen Silberzahn

For many years, NMP was the most important solvent in coating removers that were used primarily to strip aluminium parts. Now, the changeover to products which do not contain NMP has largely been completed and has even been accompanied by an improvement in the results of the coating removal process. PDF-Download

High-Quality Finish with Ultra-Thin Coatings

Springer Fachmedien Wiesbaden

Ultra-thin powder coatings are used among other things to reduce powder consumption. The example of the bicycle manufacturer Derby Cycle illustrates the benefits of this type of system. The quality of the finish on the company’s bicycle frames has improved significantly since the changeover to ultra-thin powder coatings. PDF-Download

Powder Output More Consistent and Controlled

Springer Fachmedien Wiesbaden

The automotive industry requires high standards of quality and punctual deliveries. In order to meet these requirements, a Czech manufacturer of heat exchangers and condensers decided to install a new application system, which enabled the quality of the coatings to be improved without reducing the thermal performance of the components.

Painting Cars More Efficiently

Dr. Michael Schlipf

As much as 70 % of the energy needed to manufacture a car is used in the painting process. If energy savings of more than 75 % can be achieved in this area, the result is not only a huge drop in production costs, but also a reduction in CO emissions. The paint shop at Volkswagen’s plant in Bratislava has demonstrated that this is possible. PDF-Download

Cost-Cutting Overspray Filtration System

Eike Ostendorf-Servissoglou

A metal construction company has installed a new filtration system for overspray in its paint shop where large and complex components are painted by hand. The compact dry filter system has a low energy consumption and a long filter service life. PDF-Download

Flexible Solution

Peter Kalkenings

A high-performance solution was required at short notice to protect the surface of high-strength lockbolts for use in the automotive industry, which most importantly had to have a low curing temperature. A zinc flake coating met these and other requirements and provided a black top coat to give the necessary high-quality finish. PDF-Download

The Benefits of Paint Recirculation Systems Combined with Pressure Tanks

Springer Fachmedien Wiesbaden

Recirculation systems are often used to supply spray guns with paint and are essential for materials with a tendency to form sediments. If important factors include handling the materials with care, producing first-class finishes and, at the same time, saving energy, systems with pressure tanks are the ideal alternative to those that use only pumps.
