armaturesSinotech is truly one of the few remaining totally integrated suppliers of specialty custom windings in the electromechanical motor and gyro industries. All laminations are stacked using critically designed stacking tools and fixtures. This is one of our specialties and the heart of our business.

Our superior machining capabilities enable us to commonly manufacture to .0003″ tolerances total on O.D.’s and I.D.’s. If the application demands, closer tolerances can be obtained. Sinotech builds custom bobbin windings which employ unique transfer molding technology for high dielectric requirements up to 1,500 volts.
