Toolshop and Technology Center Oberegg

Since our foundation in Oberegg, Switzerland in 1971, the Toolshop and Technology Center has been an integral part of thyssenkrupp Presta AG, as part of the Presta Cold Forging (PCF) operating unit. 

Our focus is on quality, precision and innovation in the production of tools for cold and hot forging, rotary swaging, tube forming, prototype parts, machine parts measurement and test equipment. As part of thyssenkrupp Presta AG, we combine state-of-the-art technology with our regional roots in the Appenzell area of Switzerland. We specifically promote skilled workers and train our apprentices, particularly tool makers and industrial mechanics, in our own training workshop. Our production also follows clear principles of sustainable manufacturing, incorporating energy-efficient processes and the conservation of resources.  

Our team of around 120 specialists manufactures products for our own use at thyssenkrupp Presta AG, as well as for external customers in the DACH region and Liechtenstein. Our efficient processes and automated production technologies ensure consistent quality for automotive and non-automotive applications, as well as for contract manufacturing in the industrial sector. 

Expertise

Thanks to our high level of vertical integration, we offer our customers maximum efficiency and quality – all services from a single source – from planning and production through to quality assurance. This 
enables short response times, maximum flexibility and seamless realisation of technical requirements. 

Turning and milling

Turning and milling by thyssenkrupp Presta Oberegg

We use state-of-the-art CNC machines for soft and hard (HSC) machining in turning and milling. For turning, we use double-spindle lathes, live tools and bar feeders. For milling, we use 3- and 5-axis machines with large pallet and tool storage systems. Our automated systems enable stable processes, maximum autonomy, high repeat accuracy and precise results in both single-part and serial production. 

We can process all common materials, such as plastics, aluminum, copper, graphite, steels and hard metals. We maintain a substantial inventory of materials to ensure prompt response to customer requirements.

Grinding

Grinding by thyssenkrupp Presta Oberegg

We offer a wide range of grinding technologies. 

  • Surface grinding 

  • Profile grinding 

  • cylindrical grinding 

  • Offset grinding 

  • Tool grinding 

  • Polishing grinding

We use modern machinery to manufacture carbide dies, precision gear punches and much more. By using abrasives and flexible systems in a targeted way, we achieve the highest surface quality and dimensional accuracy, even with complex geometries. 

EDM (Electro-Discharge Machining)

Electro-Discharge Machining by thyssenkrupp Presta Oberegg

Whether it's wire EDM (wire cutting), die sinking, or robot-supported placement, in-house manufactured electrodes (made of copper, tungsten copper and graphite) and integrated measuring systems ensure maximum precision and top-quality surface finishes. Our experience and technology guarantee consistent results, even with the most challenging contours.

Hardening

Hardening by thyssenkrupp Presta Oberegg

Our modern vacuum and tempering furnaces enable us to carry out precise in-house heat treatment. This allows us to coordinate the hardening process and subsequent machining optimally, which is a decisive factor for producing precision tools that are dimensionally accurate and durable. We can also respond flexibly and quickly to customer requirements, offering optimum lead times.

Surface finish

We use processes such as profile polishing, cylindrical polishing, honing, drag polishing and vibratory polishing to meet our customers' requirements. Using surface measurement technology, microscopy and profile scanning, we ensure that the structure, roughness and shape accuracy correspond exactly to the specifications. We also use surface densification and shot peen.

Coordinate measuring technology

Our tactile measuring machines from Zeiss (Prismo Ultra) enable automated and manual 3D measurements with the highest precision. We offer serial measurements, in-house certificates for prototypes and test equipment construction. We also support complex measurement tasks, such as form-position tolerances, in accordance with ISO 9001 and IATF 16949 standards. We also carry out gear profile measurements, documentation and optionally, laser marking of test features. We are a  reliable measurement service provider along the entire production process.

Products

Our extensive product portfolio is designed to meet the diverse requirements of the automotive and non-automotive industries. It comprises solutions for a wide range of applications and is divided into six segments:

Forging tools 

Forging tools from Thyssenlrupp Presta Oberegg

We manufacture high-precision cold and hot forging tools for industrial serial production. Our dies, punches and basic tools deliver precise forging results in the automotive industry and beyond. Thanks to our many years of experience and modern manufacturing processes, we guarantee reliable processes, consistent results and durable tools with a long lifespan.

Rotary swaging tools

Rotary swaging tools by thyssenkrupp Presta Oberegg

Our rotary swaging tools form tubular components with complex internal and external geometries, for example for steering shafts, steering spindles and steering wheel connections. We manufacture high-precision mandrels and hammer dies that deliver consistent results, even during intense forging processes.

Axial and radial forging tools

We supply axial and radial forging tools such as dies, mandrels, punches and supports, tailored to the processes and products of our customers. Our tool sets ensure stable processes, high efficiency and reduced costs.

Prototypes

Prototypes by thyssenkrupp Presta Oberegg

Another strength lies in the production of complex prototype parts made from all common materials, such as aluminum, steel and hard metals, with the highest precision and in the shortest possible time. Examples include steering parts such as gear racks, pinions, toothed parts and housings for steering gears and columns. We support the engineering department with production-oriented design and 3D measurement planning.

Precision parts and assemblies

Precision parts and assemblies by thyssenkrupp Presta Oberegg

Our production department supplies precision parts and assemblies for a wide range of applications. These include mechanical devices, setting masters and measuring devices including MSA V1 certification. The high quality of our components ensures reproducible results in serial production. On request, we provide documentation with a measurement report and assembly journal.

Automation and machine parts

Automation and machine parts by thyssenkrupp Presta Oberegg

We manufacture complex automation and machine parts for use in assembly systems, production units and large presses. Our CNC-controlled production process guarantees precise fitting of every component and smooth production. 

Thanks to our high level of vertical integration, we can provide timely solutions from a single source.
