When perfection in small parts makes a big impact
Our broad production range covers a wide variety of high-quality products, including electrical insulation materials as roll goods or as insulation parts such as slot wedges, slot liners, phase separators, stamped, bent and formed parts, produced with a high degree of flexibility and enthusiasm for innovative technologies.
Insulation parts
Stamped and formed insulation parts for stators and rotors.
Slot Liners for Electric Motor Stators
Slot liners separate the winding from the core and prevent flashovers in the stator slot.
