Positive Signs for Paintexpo 2024

Registrations for the world's leading trade fair for industrial coating technology are already at an excellent level one year before the next edition of the event opens its doors from 9 to 12 April 2024 in Karlsruhe. PDF-Download

Intuitive Robot Programming and Intelligent Tools

Mohamad Bdiwi

A research institute has developed a multimodal human-robot interaction tool that allows robots to be programmed intuitively via gestures and voice commands without any programming knowledge at all. In combination with an intelligent tool that is independent of the robot's track, it results in promising application possibilities in painting technology. PDF-Download

Use of 2K Paint Spraying System Makes School

An end customer in Thailand wanted to carry out pipe coating with a specific 2K polyurethane paint. In search of a reliable plant for processing the coating material, he contacted the regional distributor of a German plant manufacturer. The selected 2K paint spraying system proved to be successful. It is now regularly used by the dealer's customers with similar applications. PDF-Download

Innovations in the Field of 2K Application Technology

A supplier of spraying and painting systems will present various innovations in its 2K application technology: from 2K controllers to gun manifolds and automation technology. PDF-Download

More Energy Efficiency in Paint Drying

Especially in the automotive industry, the factors influencing the drying process of individual components or entire car bodies are manifold. In particular, the relationship between drying time and drying temperature plays a decisive role here. At the same time, however, the requirements with regard to environmental protection and CO savings are also increasing. A purely electric solution is emerging as an efficient alternative to the usual gas-fired drying systems. PDF-Download

Coat with High Quality and Save Powder at the Same Time

Ryszard Sytniewski

A Polish manufacturer of powder coating equipment has developed a manual coating line based on its more than 30 years of experience. Advantages for the user are said to lie primarily in the optimization of costs and the increase in production quality. PDF-Download

Meeting Growing Customer Requirements

Markus Rhode

A successful sheet metal processor from Schwäbisch Hall (Germany) invests in its own powder coating plant. The efficient and flexible plant gives him planning security and short delivery times. PDF-Download

Save Energy by Lowering the Baking Temperature

Christoph Schumacher

The development of energy costs and the increasing uncertainty regarding the supply of energy represent major challenges for the entire industry. Powder coatings are chemically cured at higher temperatures and are therefore particularly affected by this issue. Coating systems that allow lower oven temperatures, shorter curing times and longer coating life are therefore right in line with the times. PDF-Download

CDC and Powder Coating With Only One Stoving Process

Henning Schlüter

Initial results in the development of a new process for sustainable corrosion protection with electrocoat and powder coatings offer a promising approach to a more economical coating solution. A topic that is more topical than ever with the currently rising costs of energy and raw materials. PDF-Download

A Single Bath for the Complete Process

Joachim Schönberg

With no environmental impact, in a single process step and with a minimum of peripheral equipment and consumables: A new process for pretreating metals before hot-dip galvanizing promises significant benefits. Practical experience confirms the performance of the technology. PDF-Download

Masking Can Be Done in a Different Way

The use of a light-curable masking material opens up significant advantages for a German engine manufacturer. Instead of manually masking the areas of the components that are to be protected from certain surface finishing steps, they are now temporarily sealed with the protective coating automatically, quickly and with high precision.

Focus on Sustainability

Maximilian Frisch

A global surface treatment specialty chemicals company is focusing on sustainability: From using sustainable raw materials to using recyclable cleaners to reducing process temperatures. PDF-Download

Quickly Quantify Extractable Soluble Residues

Martin Fahr

Since this year, a guideline for a new method for determining the mass of extractable soluble residues, often also referred to as filmic or chemical residues, is available. Now there is also a suitable measuring device for this method. PDF-Download

Future-Oriented Component Cleaning

The production of high precision parts with complex, internal geometries requires top quality along the entire production chain. In order to be optimally prepared for future cleanliness requirements, a Swedish parts manufacturer replaced one of its solvent cleaning systems. The choice fell on a single-chamber system operating under full vacuum, which is equipped - among other things - with a special ultrasonic process. PDF-Download

Decoating and More With 2500 Bar High Water Pressure

Jens Hotze

There are many ways to remove paint from buildings, ships, lock gates, tanks, masts and the like and to prepare the substrate for recoating or for further restoration and cleaning measures - mechanically and chemically. In the case of mechanical processes, ultra-high-pressure water blasting is an advantageous option. PDF-Download

New Perspectives for Induction Coating

Jan Kondas

How to achieve aluminum cookware induction? The conventional coating processes are not corrosion-resistant, inflexible and the thermal conductivity of the finished products is not ideal. Cold spraying offers a further development here that opens up new perspectives. PDF-Download

Reliably Measure Coating Thickness

A mechanical engineering company not only processes its own sheet metal and steel parts in its surface coating center, but also carries out contract orders. In the case of a large-volume order, the required coating thickness could not always be optimally maintained due to a new type of powder coating prescribed by the customer. To ensure consistent quality, it was necessary to check the coating thickness before baking. PDF-Download

How Many Diamonds Would You Like to Have?

Diamond pastes are mostly used for precision machining in tool and mold making. Depending on the material of the workpiece and the desired surface, users can choose from a variety of products available on the market. However, the required result cannot always be achieved with such standard products. Individual solutions are then necessary. PDF-Download
