Not only the automotive industry is characterised by complex systems whose individual modules are brought together to form a new overall concept. During the product development stage, long before the start of series production, prototypes are employed for the qualification of the design and the functional requirements, and allow the customer to gain an impression of the finished product.

These prototypes are produced with great care and experience, involving all the suppliers.

The demands of the customers on the prototypes differ widely, depending on the type of application, and often vary during the course of the product development process.
