PaintExpo — Answers for Demanding Coating Requirements

Ever greater demands are being placed on surfaces, and thus on coating technologies as well. With numerous new and further developments, the exhibitors at the 5th PaintExpo will provide answers on how these challenges can be met. The leading international trade fair with roughly 430 exhibitors will take place at the exhibition centre in Karlsruhe from the 8th through the 11th of April, 2014. PDF-Download

All-Over Coating

Benseler Oberflächen GmbH

At the beginning of the year, Benseler, a provider of surface finishing services, brought into operation a new dip-spin coating system for zinc flake coatings on rack parts. The plant is one of the most modern in Europe, in particular with regard to its level of automation and its low environmental impact. PDF-Download

Corrosion Protection for All Eventualities

Martin Welp

In the field of corrosion protection zinc flake technology has been proven over the course of 30 years of use. However, in specific areas of application this technology comes up against system-related limits. This gap is now being filled by two new systems: an environmentally-friendly electroplating range and a high-performance KTL (e-coat) coating system. PDF-Download

Coating Brake Discs with Customised Solutions

Martin Grau

A number of factors influence the design of coating machines for brake disc coating, including the geometry of the discs, the coating specifications and the paint systems. Tailor-made individual solutions guarantee the greatest possible flexibility and the most reliable processes. PDF-Download

Low-Maintenance Spray Wall with Dry Separation

Rippert Anlagentechnik GmbH & Co. KG

Modern separation systems allow large volumes of paint with an unavoidable level of overspray to be processed cost-effectively. A low-maintenance spray wall with dry separation reduces costs and set-up times when compared with conventional systems. PDF-Download

Applying Paints with Nitrogen

Peter Spang

Companies in some countries already have experience of atomising paints using nitrogen. Tests carried out in one machinery manufacturer’s technical centre have produced very positive results and these have now been reinforced by the successful use of the process in volume production. PDF-Download

UV Protection and Corrosion Protection for Agricultural and Construction Machinery

Andreas Segin

When the search is on for cost reductions in the painting process, the first port of call is always the cost of the paint being used. However, the chances of achieving significant savings in this area are low. More money can be saved by reducing the thickness of the coating, but there are limits to what can be achieved in this area too. PDF-Download

Three New Oven Heating Concepts

Oliver Iglauer

Curing vehicle body paint is the most energy-intensive part of the automotive finishing process. It is responsible for around one third of the total energy consumption. This article presents three new oven heating concepts which bring significant reductions in the operating costs and CO emissions of paint shops. PDF-Download

Heavy-Duty Corrosion Protection Coatings with an Aesthetic Appeal

Karl Bubenhofer AG

The phrase “heavy-duty corrosion protection” brings to mind thick coatings with rough surfaces, which are not exactly attractive to look at. But coatings that provide heavy-duty corrosion protection can also have a pleasing appearance. A combination of a powder primer and powder top coat applied to a hot-dip galvanised substrate is what makes this possible. PDF-Download

Coating Individual Passenger Seats Efficiently

Gema

Increasingly, the seats in buses and trains have individual designs consisting of a variety of components, colours and materials. One seat manufacturer has invested in a modern powder coating system which allows it to coat small batches of its products efficiently. The new solution has significantly reduced colour change times and keeps powder wastage to a minimum. PDF-Download

Ultrasonic Sieving — Practical Hints and Tips

Michael Topp

Ultrasonic sieving has become an essential aspect of modern powder coating plants. In order to sieve powder effectively and efficiently, the sieve must be treated with care and regularly maintained. Below are some tips for installing and operating an ultrasonic sieve. PDF-Download

Cleaning and Phosphatising Robot Housing Components

Robert Huber

Replacing aluminium with spheroidal graphite cast iron led to new challenges for parts cleaning at a robot manufacturer. The problems were solved by a water-based system in which the robot parts are not only cleaned but also iron phosphatised. PDF-Download

Criteria for Selecting the Correct Cleaning System

Jens Emmerich

What should users take into account when planning a new cleaning system and choosing a suitable process? Many different parameters need to be considered. A variety of different aqueous cleaning processes is available and these processes can be adapted to meet individual requirements. PDF-Download

Chrome-Free Pre-Treatment of High-Class Aluminium Profiles

Dipl.-Ing.(FH) Mike Schirdewahn

A job coater has successfully converted its chromium(VI)-based pre-treatment process to chromium(VI)-free silane-based technology. Thus, the company already meets future REACH requirements and supplies high-quality, chromium-free aluminium profiles to renowned facade construction companies. PDF-Download

Cleaning Agents Based on Renewable Materials

Inventec Performance Chemicals Deutschland

A new highly efficient cleaning agent has been developed for precision degreasing using a vacuum process. The new product is based on biodegradable raw materials. PDF-Download

Effective Measurement of Corrosion Protection Coatings

Helmut Fischer GmbH

Measuring the thickness of corrosion protection coatings presents a wide variety of challenges for users and measuring systems. A revised range of handy, easy-to-use thickness measuring devices offers high levels of functionality and precision, together with a compact and robust design. PDF-Download

Metal-Coated Carbon Fibres for Multifunctional CFRPs

Dr. Falko Böttger-Hiller

A research project has been set up to coat carbon fibres with metal using vapour deposition and electroplating processes. These methods provide the opportunity of applying evenly distributed metal coatings of different thicknesses to the carbon fibres. This new approach has the potential to provide solutions to challenging problems, such as the development of wear-resistant lightweight structures. PDF-Download
