Since 1957, the Sefag name has stood for quick, tailor-made solutions to any connection problem.

The promise of finding a reliable, long-lasting solution for any challenge is based on our experience and technical know-how. We not only design and develop our components and systems ourselves – we manufacture them too.

Our technical know-how in the field of metalworking is comprised of the following areas:


  • Pressing
  • Bending

Cutting and machining

  • Cutting (water jet / laser)
  • Stamping
  • Turning
  • Milling
  • Shearing


  • Welding (copper, aluminium, steel)
  • Electron beam welding
  • Pressure welding
  • Brazing / soldering


  • Electroplating (silver, tin, nickel)
  • Painting

Thermal treatment

  • Tempering
  • Annealing


It goes without saying that we use state-of-the-art CNC precision machining in manufacturing applications. We can then guarantee short turnaround times for prototypes, individual parts and small series in line with our goal of finding the right solution – even under tight schedules.
