ARRKARRK - One of the world’s largest product development specialists For over 70 years, the ARRK Group, which employs over 3,800 people world-wide, has assisted companies from a wide variety of industrial sectors with the integral development of new products or the optimisation of existing ones. The competencies of its four European divisions – Engineering, Prototyping, Tooling and Low-Volume Production – cover every stage of the process from the original idea to series production, allowing the delivery of a one-stop service. This creates ideal conditions for efficient interaction of the various disciplines, and generates valuable synergies that help bring innovative products quickly and reliably to market. That's why an array of renowned manufacturers and component suppliers – specialising for example in automotive engineering, aerospace and special and commercial vehicles – are already taking advantage of the Group's extensive service portfolio.  Optical Systems Engineering, Prototyping, Tooling & Low-Volume Production Our Center of Competence for Optical Systems covers all disciplines involved in their development, especially components and systems for connected display systems, lighting systems and image processing. ARRK undertakes the whole development process from concept and series development right through to testing and integration, prototyping, tooling and low volume production.
