Tungsten Carbide Mandrels & Plugs

Mandrels & Plugs

We can manufacture mandrels & plugs in steel ,steel/carbide, or just carbide. The steel/carbide mandrels can be assembled mechanically or brazed together.
Mandrels & Plugs are used to form and size the inside diameters of tubes. These can be held in place using rods which attach to the mandrel assembly usually with threads. Other mandrels simply "float" in the tube, being held in place by the drawing process.
  • Braze-Type Mandrels
  • Sleeve-Type Mandrels
  • Floating Plugs

Swaging Die Specifications

All United Die mandrels & plugs in either the steel/carbide or carbide configuration can be made with a variety of tungsten carbide grades.
