Summary
Tempel is an electrical steel lamination producer that its website describes as a Worthington Steel company. It makes motor and generator laminations (stamping as thin as 0.20 mm) and transformer laminations (E and I cores, DG cores, step-lap miter cores) for eMobility, transportation, industrial motors and energy markets. The site lists Chicago, Illinois as a US manufacturing location and as its 1945 founding site, with East and West Coast distribution centers, and lists manufacturing in Canada, China, India, Mexico, Germany, Italy, Slovakia, France and Switzerland. Certifications shown are ISO 14001:2015, C-TPAT, IATF, ISO 9001:2015 and OHSAS. Robotics is not mentioned; relevance is through the same lamination stacks used in frameless and servo motors. Worth noting for sourcing work: the global footprint includes a manufacturing site in China, so the Chicago pin should be read as US capability within a multinational network.
