Plasma coatings are successfully used in various industries. However, the use for coating internal geometries is often not possible at all or only with considerable restrictions. One company offers a solution for this - and achieves high coating speeds in the process.

In order to provide steel components with long-lasting protection against corrosion, they are hot-dip galvanised. But particularly large, complex steel constructions often pose an enormous logistical challenge. A renowned company not only galvanises, but also has logistical solutions ready for such cases.

Climate, tartaric acid and chemicals require the best possible corrosion protection for viticulture machinery. For this, one manufacturer successfully relies on a specially adapted paint system.

For the machining of large surfaces, there is now an industrial-grade robot grinding solution whose contact pressure adapts sensitively to the specific nature of the surface.

Workpiece coolers are used where rapid and defined cooling of the process-related heating of workpieces is necessary for testing or further processing.

New technology: Laser cleaning as well as laser pre- and post-treatment of surfaces and for sealing and connecting surfaces. There are about 30 applications in automotive engineering alone, especially in electromobility.

Conventional deburring processes, such as high-pressure water jetting, vibratory grinding, chemical, electrochemical as well as manual deburring or brushing, tend to cause high costs, the removal takes place in an untargeted manner and can lead to high environmental pollution or secondary burrs. A funding project wants to change this.

More power through less weight is the motto of e-mobility. Shot peening compacts the material of fragile components and extends their service life. A well-known contract service provider therefore invested in a new shot peening system.

Powder-metallurgically produced components cannot be galvanically coated without further ado. Other processes must be used to protect them from corrosion.

Precise adherence to coating thicknesses is an important quality parameter in modern automotive painting. The problem here is that the non-destructive methods commonly used today often fail with multi-layer systems. A new type of paint inspection system based on terahertz waves promises an industrial solution.
