Technical ceramics for wire production and cable industry
Using advanced technical ceramics, we help wire and cable
manufacturers reduce costs and improve yields with longer-lasting,
higher-performance ceramic wire drawing components. For four
decades, we have supplied superior quality capstans, pulleys, and
rollers for wire drawing — from rod breakdown to ultra-fine wire
processing equipment.
