Formitt Metal Labs: Seamless Solutions for Hollow Tube Shapes & Components

Updated: Apr 25

At Grotnes, precision and innovation in metal forming are our day-to-day reality, brought to life by our prototype initiative, Formitt Metal Labs.


Through a synthesis of advanced machining and engineering, we excel in co-manufacturing bespoke, hollow tube shapes and components. Our expertise spans across essential components such as exhaust catalytic converters, offering cost-effective and quality-driven solutions. But Formitt Metal Labs’ contribution doesn’t stop at prototyping. With more than 120 years of industry expertise, we’re pioneers in process innovation, focused on reducing waste and enhancing efficiency. Our development and production services cater to diverse sectors, from automotive to marine exhaust components, ensuring each client receives tailored solutions.


Leveraging the advanced capabilities of Grotnes machines, Formitt Metal Labs provides smaller production runs that cater to the initial stages of product development. This approach is particularly beneficial for customers who are in the process of scaling up their operations. Initially, when the production requirements are modest, our clients can rely on Formitt for high-quality, custom-made components. As their production needs grow and they approach a scale where owning a Grotnes machine becomes essential, we ensure a seamless transition. This flexibility not only helps in maintaining quality during the critical phase of product growth but also provides a cost-effective solution for our customers during their journey from prototyping to large-scale production.

Our North American facility is rare in its capability to fully develop on-site processes, a feature that allows us to deeply understand and meet your long-term production needs. Whether the task is to manufacture components or assist in transitioning to independent machine operation, Formitt Metal Labs is committed to ensuring a smooth path for our partners.
