On November 26, 2025, SOTEC GmbH & Co KG from Ostelsheim (Calw district) acquired Avatec GmbH, based in Sindelfingen, as a 100% subsidiary. Founded in 2009, Avatec specializes in surface finishing through vibratory grinding (mass finishing). In addition to meeting technical requirements such as deburring of highly complex contours, the finest grinding media can also achieve a finishing that meet the highest standards. SOTEC looks back on 45 years of experience in the developm
