Magnetic Pulse Crimping and Expansion

Magnetic Pulse Crimping and Expansion are technical and economic alternatives to mechanical processes. Using the same principles as Magnetic Pulse Forming and Welding, our MP Crimping and MP Expansion systems can shrink or expand elements – enabling new designs with extreme mechanical properties.

Not limited to soft alloy structures, MPC allows high-strength steel parts to be processed. In fact, MPC enables a wide range of assemblies, including metal to polymer, composite, ceramic, cast metal, or glass. All of which can be achieved without the need for adhesives, riveting and welding.


For cable crimping applications, zero clearness and maximum contact area provide higher conductivity, thermal transfer and heat-shock resistance. The electrical resistance of MP crimped cable connectors is typically 50% lower than of those produced by mechanical crimping.

Competitive advantages of MPC
  • A more uniform crimp than mechanical processes (with no radial or longitudinal misalignment)
  • Hermetic or non-hermetic crimping, swaging or assembling of parts are possible
  • Ability to compress almost any tubular cross-sections (e.g. round, elliptical or rectangular)
  • Minimal set-up time between different workpiece geometries
  • Excellent repeatability
  • Outer pieces can be designed with less material
  • No uneven joints (therefore no sealants required)
  • No moisture or liquids will penetrate and no corrosion attack will occur
  • Accepts blanks with a wide range of tolerances
