For precision work, we have hydraulic presses with a pressing force of 100 to 1,600 tons and a press table size of up to 3500 x 2000 mm at our disposal.

Metalforming in highest quality.

Whether deep drawing, embossing or bending - we form sophisticated components from steel, stainless steel and aluminium for end products from a wide variety of industrial sectors. Cold forming from a single source, along the entire value chain. From the planning and consultation to the conception and development of the production technology up to the finished installation part for the final product.

Look forward with us to a strong, experienced partner for the realisation of your projects - a real industry professional. Competent, reliable and flexible. More than 125 years of know-how and continuous healthy growth speak for themselves.

Clean Cuttings.

When it comes to cutting methods, we use 2D and 3D laser technology. This enables us to adapt quickly: customers can make change requests during the development phase. In addition, this technology saves costly and time-consuming punching tools - which is particularly interesting for the production of small quantities.

Perfectly connected.

We produce sophisticated welded assemblies from our deep-drawn parts according to customer specifications, some of which are machined and completely ready for installation. Naturally with the highest degree of precision and best quality thanks to our flexible robot welding cells at all locations.

In addition, we offer our customers the complete spectrum of welding technology. With MIG, MAG, TIG welding, stud welding, spot welding and projection welding, we solve even the most difficult welding tasks.
Whether 1 or 2 robots per welding cell - large or small components - we have the right system concept for every application.

The finishing Touches.

Our customers can always expect the best results from us. We supply surfaces that meet the highest quality standards. We give the products the appropriate surface finish according to the customer's wishes. We use the techniques of grinding, polishing, blasting, pickling and vibratory grinding.

Everything in paint.

The requirements for decorative surfaces and durable corrosion protection are becoming more and more important for our customers. Therefore we offer individual solutions in cooperation with long-standing and powerful partners. These include wet paint, powder and KTL coating as well as screen printing processes.

Here it runs smoothly.

Mastering speed and complexity in the logistics chain is one of the greatest challenges of our time. In order to support our customers in these challenges, we can offer all common logistics concepts (JIT, JIS, sequencing, KANBAN, etc.). We can supplement this with any kind of assembly work and packaging concepts. This enables us to offer a comprehensive service in order to reduce complexity for our customers.

Exactly measured.

Quality assurance must take place where production takes place. In this way, production errors can be detected immediately, and in the best case even avoided. To check whether the parts correspond to the customer's drawings while observing the specified tolerances, we have state-of-the-art measuring technology at our disposal: 3D measuring machines as well as measuring articulated arms that can be used flexibly anywhere. With this technology, we are able to measure during the process and thus keep quality under control at all times.

Everything from one source.

The in-house design, manufacture and maintenance of our equipment is the basis for our performance. Our tool shop ensures the ongoing maintenance and repair of more than 4,000 tools and fixtures. New tools up to a size of 2,800 x 1,600 mm and a weight of up to 15 tons are manufactured there. Our design engineers accompany the components throughout the entire process. Starting with the construction of the tools, over the try out up to the running series. The forming simulation complements our decades of experience and enables us to find optimal and economically valuable tool solutions for our customers.

Whether deep drawing, embossing, laser cutting, welding or assembly - we form sophisticated components from steel, stainless steel and aluminium. For end products from a wide variety of industries. We develop and design the necessary tools and fixtures in-house - 360° service from a single source.
