Cold Forging of Copper – Form-Fitting, Conductive and Durable
Copper is electrically conductive, corrosion-resistant, and easily formable – but also demanding to process. Cold forging enables the production of highly precise functional parts from copper – without material loss and provided the base material is free from sulfur and lead. Walter Schneider is your contact for complex copper components, even in smaller quantities, from tooling to series production.
Why Cold Forging Is Ideal for Copper
In cold forging, the copper is pressed into a tool at room temperature – not cut, not heated. This enables:
- High dimensional accuracy without reworking
- No material losses – 100% of the raw material is used
- Continuous grain orientation – for maximum fatigue strength
- Suitable for forming lead-free copper alloys
- Smooth surfaces without burr formation
Especially for sensitive or thin-walled components, forging offers great advantages over traditional methods.
Cold Forging Compared to Alternative Copper Forming Methods
Many methods quickly reach their limits when forming copper – be it due to the material behavior or the desired precision.

Your Advantages with Cold Forging of Copper
High Dimensional Accuracy
Components with tight tolerances for connectors and contact surfaces – produced directly from the tool, with no need for reworking.
Full Conductivity
Due to the preserved grain orientation, electrical conductivity remains consistently high – no material breakage, no solder joints needed.
Lead-Free – REACH & RoHS Compliant
Optimized for High-volume Production
Automated manufacturing with integrated CAQ systems – ideal for batch sizes of approximately 50,000 parts per year.
