Cold Forming At Its Best
Cold extrusion is a high-precision metal forming process in which material is shaped under high pressure.
In the production of complex components, the metal passes through multiple forming stages. The wire is successively formed within a series of dies and punches until the final geometry is achieved.
Greater Stability With Less Material
Cold extrusion combines efficiency, flexibility and cost-effectiveness unmatched by most other manufacturing processes. Key benefits include:
Strength
Full Power
Speed
Less Money

High Precision
Good for Business

Cold Pressed. Precision Without Compromise.
Cold extrusion is a high-precision forming process in which metal is shaped under extreme pressure without prior heating. The material is pressed between a punch and a die, flowing in a controlled manner into predefined cavities until the final geometry is achieved.
With 16 single- and double-stroke presses as well as 42 multi-stage presses with up to six forming stages, we process a wide range of material grades with maximum precision. Even complex components are manufactured efficiently from a simple wire blank — precisely tailored to your specifications.
Discover Our Approach
Every successful component begins with a concept — and the right expertise to transform it into reality.
With a structured, engineering-driven approach, we support you from initial consultation through final production planning. Our goal: components that meet the highest technical standards while ensuring cost-efficient manufacturing.
If required, we provide turned prototypes made from the original material for early validation of form, function and material behavior — all within our integrated single-source production concept.
When Ideas Take Shape
The majority of our components are individually engineered special parts. With a clear focus on maximum precision and complex geometries, we develop efficient solutions for a wide range of demanding applications.
Cold extrusion delivers exceptional surface integrity and superior dimensional accuracy. At the same time, it enables significantly higher output rates – in many cases up to ten times faster than conventional turning processes.
The Power of Combined Manufacturing
Cold extrusion often replaces conventional turning processes. If specific design features cannot be fully realised through forming, we integrate subsequent machining operations.
Features such as cross bores, grooves perpendicular to the axis or internal threads may require additional processing. By combining forming and machining where necessary, we ensure complete design freedom without compromising efficiency.

Less Material, More Options
Cold extrusion not only ensures maximum dimensional precision – it also uses material with exceptional efficiency. Thanks to the Near-Net-Shape (NNS) process, waste is reduced to a minimum, enabling material savings up to more than 90 % compared to conventional machining methods.
In Near-Net-Shape production, the component is formed as close as possible to its final geometry. This significantly reduces or eliminates subsequent machining operations such as milling, turning or grinding.
Maximum Material Efficiency: Minimal waste due to near-final contour forming
Lower Production Costs: Reduced material consumption and fewer machining steps
Higher Productivity: Shorter production cycles through reduced machining
Improved Sustainability: Lower material waste and reduced energy consumption
