ARRK|P+Z Engineering
For nearly 50 years, we have providing active product development support to customers from the automotive,
aerospace and special and commercial vehicle industries and machine building and plant manufacturing. You
can count on innovation, dependability and sustainability for smooth development of your product,
underpinned by our five areas of competence – Design, CAE & Simulation, Test & Validation, Electrics &
Electronics and Project- & Quality Management.
ARRK Group
Back in 2005, we became a leading member of ARRK - an international group of companies with 20 member
companies and 3,300 employees world-wide. After being part of the ARRK Group for ten years, P+Z Engineering is set to include the name of its parent company in its logo. Thanks to the cooperation with the ARRK
companies, our service portfolio will expand beyond Design Engineering to include the fields of Prototyping,
Tooling and Low Volume Production. Within the Design Engineering field ARRK|P+Z Engineering holds a
fixed and leading position in this globally operating group.
Area of competence Test & Validation
For over two decades, we have been providing our clients with support for planning, coordinating, performing
and assessing tests on individual components, entire vehicles and everything in between. We will work on your
test benches with an eye to cost-efficiency and in compliance with your quality standards. When we integrate
verification processes into your workflows, we focus on your goals and independently manage verification up
to the final approval stage.
