Top quality, from prototype to series production

Flexibility, optimal material flow and the highest of quality standards all guarantee efficient production, from prototype to series

From the production of small devices to large-scale facilities, we do our utmost to realise even the most unusual of requests. Use our production power for your success.

Our production capacities are geared towards customer-specific development prototypes, the subsequent series production of those prototypes and the production of our own products.

This calls for a wide range of mechanical and electrical designs, which is made possible by the extraordinary flexibility of our work processes and internal logistics.

With its strong emphasis on craftsmanship, our highly efficient manufacturing process is capable of producing large systems in control cabinet form just as efficiently as very small devices in 19" plug-in units.

Warehouse space of 400 m², combined with an optimised merchandise management system, ensures a smooth material flow.

Like all the other areas of GVA, the production division is staffed by specialists who adopt and implement new techniques and rise to new challenges with great enthusiasm.

Prototype construction

An important stage in the evolution of a product is when the development results are turned into a real prototype for the first time. At this stage it becomes clear whether or not the requirements and design specifications arising from the development process can be implemented in production without difficulty.

A continuous exchange of information between our production and development staff helps identify critical points at an early stage, thereby minimising potential problems during equipment assembly.

Once the prototype is finished, you will receive documentation checked and verified in accordance with DIN.

Quality assurance

All of our products undergo a 100% output test once they are completed. The scope of testing is individually determined and assigned to every single device in the form of test reports or protocols.

Tests which cannot be carried out in-house are either carried out at the customer's premises or outsourced to appropriate institutes.

Over 90% of our customers who commission us to provide development services also have their devices manufactured by us.

Long-standing, well-qualified partners in metalworking and sheet metal processing, circuit board manufacture, assembly and cable manufacturing contribute to GVA's high level of quality, which ensures the reliability of several tens of thousands of devices in heavy duty day-to-day use.

All of our divisions are DIN ISO 9001-certified and are subject to continuous checks by internal and external auditors.
