GROB Prototype Manufacturing: From Concept to Production – with GROB as Your Development Partner

Precision, Speed, and Scalability: Near-Production Prototyping for a Seamless Transition to Mass Production

As an experienced development partner, GROB supports you every step of the way, from the first prototype to the production system ready for series production.

Through our near-series prototype manufacturing, state-of-the-art manufacturing technologies, and an integrated process chain, we ensure that your components are not only functional but also fully suitable for series production.

Our prototype manufacturing relies on the same technologies used in subsequent series production. This allows us to achieve an exceptionally high degree of process consistency and quality.

We work with, among other things:

  • State-of-the-art 5-axis universal machining centers and system machines
  • Machining centers for frame structure and chassis components
  • Systems for mega- and giga-castings

The result: near-production components that can be transferred directly into validated manufacturing processes—ideal for optimization during process commissioning.

Holistic Development – concurrent engineering for maximum production readiness

Using a holistic development approach, we ensure that production requirements are taken into account from the very beginning.
 

Our services include:

  • Concurrent engineering for early integration of production readiness
  • Concept development and functional analyses
  • Feasibility analyses for cost-optimized and robust processes
  • Tool design for stable, repeatable results
  • Clamping fixture design for reproducible, precise tasks

Your benefit: Minimized iterations, accelerated industrialization, and maximum process stability!

We offer you a complete end-to-end process chain from a single source!

What our customers say

“Developing a design is not a one-way street, because at the end of the day, the machines must be capable of producing products that are as robust as possible for pilot or mass production runs. 

GROB’s many years of experience and feedback regarding product design were extremely helpful to us.”

Matthias Venske, Managing Director
(eAx solutions)

“I was very impressed that GROB managed to get the prototype machine and automation up and running in this form. It was also fascinating that the calculations for the specified parts and their cycle times were so quickly finalized. 

Our collaboration with GROB has proven to be excellent.”

Thomas Hahn, Production Manager
(thyssenkrupp Automotive Body Solutions)

“We had a product idea, a set of specifications, and a vision of what the pilot line might look like. 

With GROB’s help, we were able to further refine our concept, essentially polish our ideas into a diamond, and thus create a first-class design for manufacturing."

Elisabeth Jahns, Director of Operations

FAQ – Frequently Asked Questions About Near-Production Prototyping

Near-production prototyping means that prototypes are manufactured under conditions that are virtually identical to those in subsequent mass production. This enables precise process validation and a rapid transition to mass production.

It reduces and minimizes production risks and accelerates industrialization. Sources of error are identified early on, and processes can be optimized under realistic conditions.

Our portfolio is particularly relevant to the automotive industry, electromobility, powertrain technology, vehicle body manufacturing, and mechanical and plant engineering.

From complex small components to large-format giga-castings, we cover a wide range of manufacturing capabilities—including aluminum, steel, cast materials, and lightweight materials.

Our end-to-end process chain enables short turnaround times. Specific delivery times depend on the component, the complexity of the project, and the production steps required.

Yes. As a plant manufacturer, we not only develop prototypes but also the complete production plantincluding process validation and handover to production.
