We can machine your forgings, turn them, weld them, pre-assemble them, heat-treat or surface-finish them. 

Die Forge

Strong and
 in top form

Franz Rübig & Söhne Gesenkschmiede (Die Forge) was founded in 1946 and is the parent plant of the RUBIG Group. For decades, it has stood for innovative solutions, from the blank to the ready-to-install serial part, which are developed together with the customers.

As a competent partner for innovative manufacturing solutions, we are constantly working on technical improvements, using rationalization potentials and expanding our product range.

Solutions from a single source

At RUBIG, everything comes from a single source. From the forged part to the ready-to-install, i.e. mechanically machined, surface-finished, welded and, if necessary, assembled part, RUBIG is your competent partner. You can also count on the experience and creativity of our experienced employees to realize the development and testing of your parts.

State of the art toolmaking - the key to Flexibility and Quality

Before a new forged part can be produced, the necessary tools must be manufactured. The design alone determines the quality and cost-effectiveness of the part. RUBIG’s computer-aided design solutions are always created in close coordination with the customer and our in-house tool shop. The required milling programs are derived directly from the 3D design, resulting in precise shapes, without delays during hardening or transfer errors. The heat treatment is conducted at our state-of-the-art sister company, RUBIG Heat Treatment. All information, tools, and forgings remain in-house, ensuring absolute confidentiality of new developments.



Whether for three-point tractors, truck cranes, construction machinery, wheel or nut securing, or in formwork technology, RUBIG offers the optimal linchpin for numerous applications. We have more than 80 different types and sizes of linchpins available.


Chain Systems

RUBIG chains are the first choice for countless applications—from screen cleaning in smaller hydroelectric power plants to shredder plants, and from beet harvesters to silo cutters and manure spreaders. The matching sprockets ensure maximum quality



Our die forgings are optimized in both form and function, offering economic flexibility. Our processed materials range from simple structural steel to case-hardening and tempering steels, and even to stainless steels.
