Thin walled tubes and sheet metals can be formed contactless by EMF technology integrating our SMU equioment into your production. The impact with a joining partner results in an interference fit, a form fit or even a welded connection. The impact with a one sided cutting tool can be used for spatial cuts with minimized burring, and a one-sided forming tool can be used for calibration of sharp edged embossings. Actually, joining by compression is most relevant because the characteristic advantages of the process can be used in optimum ways:
Due to the contact-free deformation process even coated semi-finished parts can be shaped.
Due to the fact that only the workpiece to be deformed must be electrically conductive, pairs of metallic and non-metallic materials can be produced.
The high forming velocity results in a very uniform strain over the circumference of round workpiece cross-sections. So, highest requirements with respect to leak tightness and strength can be realized.
