STI Group offers state-of-the-art infrastructures, highly qualified employees with many years of experience and galvanic (WetCoat system) and plasma-based (DryCoat system) coating processes developed specifically for the automotive industry. For individual applications as well as for functional surfaces for series parts, the STI Group is there for its customers with sound technical advice and project-oriented research and development. From the first thought model to SOP and EOP, the automotive experts of the STI Group advise their customers seven days a week.


The focus of the automotive industry is on reducing carbon dioxide emissions. With its STI DryCoat and WetCoat system, STI Group offers a wide range of established assistance for the challenges this entails. The STI Group knows that each system defines its specific specifications: from the production processes of the individual components to the requirements in actual use. The load on the systems places great demands on the technical coating. In addition to optimum system costs, the coating must deliver optimum performance for both small and large series. As a full-range supplier, the STI Group offers innovative solutions for this every day.


The STI Group's portfolio is wide-ranging: from the appropriate work surface coating for deep-drawing tools of entire vehicle side parts to the specifically applied special coating of highly stressed exchangeable inserts in stamping tools. The STI Group's service is second to none: for years, its employees have ensured that their customers' stamping plants only come to a standstill when new equipment or maintenance work makes this necessary. The customer can also place the associated planning and logistics in the hands of the STI Group with peace of mind, even at weekends, of course.
