The German paint and printing ink industry is facing difficult times: High raw material costs, skyrocketing energy prices and bureaucracy are weighing on companies. On the other hand, consumers are cutting back on purchases, which is also affecting demand for coatings and inks.
At Ford's main plant in Cologne, the switch to electric mobility and high energy costs are driving technological change. In addition to extensive modernisation in the area of application and cabin technology, quality control and digitalisation projects are also on the agenda - such as the 100 per cent colour control of car bodies using cobots.
A new coating system makes it possible to thermally coat 3D-printed plastic components. This allows metal alloys such as stainless steel and molybdenum as well as hard metals such as tungsten carbide-cobalt or oxide ceramics such as zirconium oxide to be applied to plastics.
Corrosive media can only be kept out of the coating by correctly sealing thermally sprayed layers. Details of an application and material-specific sealer selection with proof of function.
The Green Deal aims to make Europe the first continent to achieve climate neutrality by 2050. Major topics here are CO2 neutrality and the circular economy. Implementation requires extensive data material, which must be compiled with the help of digitization. All in all, the industry will have to make considerable efforts.

The new High Purity Test Center of a leading cleaning technology provider was officially inaugurated at the end of November 2022 at the Dettingen unter Teck production site. It complements the company's 15 existing technology centers in the high-purity sector and enables cleaning tests for high-tech components with extremely high purity requirements.
Arc PVD technology is widely used in the production of tribological and decorative coatings. By using pulsed power supply, the roughness and hardness of the coatings can be improved. Experiments show that the target utilisation, the coating quality, but also the evaporation of target materials with poor electrical conductivity are improved.
Countless heating processes are necessary until a product is made from a metal part. Some of these processes are solved by infrared heating technology. Used correctly, the necessary energy can be used particularly efficiently.
High energy prices make it necessary to prevent unnecessary energy consumption. New, more efficient rectifiers and the use of state subsidies from BAFA offer great potential and short payback periods in this regard.
