Painting Process and Quality in Focus

For a manufacturer of bumpers for the automotive industry, the quality of the painting result and the stability of the painting process are essential factors for its long-term competitiveness. The installation of a spray pattern control system can make a decisive contribution to this. PDF-Download

Clean Air During Thermal Spraying

Thermal spraying for coating components generates fine respirable dusts. An efficient extraction system to filter out the hazardous particulate from the air is, therefore, of paramount importance. Proficiency is required when designing the workplace, because the slightest modification in materials or process parameters can bear considerable influence on the volume and types of emissions.

Bacteria Clean Exhaust Air Streams Cost-Efficiently

Painting and coating processes cause exhaust gases and vapors. To protect the environment and meet legal requirements, the exhaust air must be cleaned. Traditionally, this is done with the help of thermal processes. A plant manufacturer has developed a biological solution as a cost-efficient and environmentally friendly alternative. PDF-Download

Paint Processing - A Factor That Receives Too Little Attention

David Hoffmann

Both chemical and physical factors have an influence on the final mechanical-technological properties of a coating system. The selection of the basic chemistry of the film formers, the coating system and the coating structure play the most important roles. Another important factor is the correct application of the coating. PDF-Download

Powder Coating With Own Energy Generation

A system supplier specializing in aluminum processing was working with up to seven different job coaters. Then the idea of an own coating department came up. A subsidiary was founded and the decision was made for a powerful, flexible powder coating plant with an efficient energy concept. PDF-Download

Everything in One Booth

An Application Specialist brought a compact coating line to reality for the Swiss company Josef Hasler Maschinenbau AG. The 3-in-1 powder booth combines automatic, manual, and robotic coating in the smallest possible space. Thanks to short distances and optimum efficiency, the metal supplier now has flexible control over its production and can optimize product flow. PDF-Download

Standardized Colors Reduce Waste

The special machines from Iseli for sharpening and processing band, gang and circular saw blades, which are designed in characteristic blue and gray, are used in sawmills and by specialists all over the world. Unfortunately, large color differences repeatedly led to complaints. With the help of a system supplier, a solution was found. PDF-Download

Watch Out for Corrosion Testing

Heike Schuster

Corrosion testing is a challenging quality test for many components. The correct selection of the substrate material, pretreatment and coating play an important role here. But an incorrectly performed corrosion test can also lead to the failure of a component during the test. There are a number of things to consider. PDF-Download

Efficiency Is in the Air

Can the cleanliness required for stators for electric drives in hybrid vehicles be reliably achieved using only air as the cleaning medium? The fact that it works is proven by an application-specific dry cleaning solution. The fully automated cleaning process improved cleaning quality and reduced costs enormously. PDF-Download

Another Step on the Path Towards Digital Electroplating

Electroplating and finishing specialist C. Jentner has been progressing towards digitalisation since 2015. The most recent project is a radio-controlled, automated operation for surface finishing. JOT spoke to Marcel Scheidig, who as Head of Technology played a decisive role in the conceptual design of the process developed in-house and now running in live operation. PDF-Download

Measurement Reliability Over the Entire Life Cycle

Especially in the automotive industry, regular calibration of measuring instruments is mandatory. Test process suitability in accordance with VDA Volume 5 is now well established. As a calibration service provider, a sensor manufacturer ensures that its coating thickness measuring comply with these specifications. PDF-Download

The Cobot Puts the Finishing Touches

Daniel Rubarth

Whether grinding, sanding or polishing - the finishing of surfaces is an art in itself. Achieving optimum results requires consistent force intensity and maximum precision. Until now, these processes have been difficult to automate. Collaborating lightweight robots - equipped with the appropriate sensor technology - can do just that. PDF-Download
