    • Description
    Description

    Our company specialises in the production of automotive generator slip rings, and has done so for over 30 years. Our products have stood the test of competition well.

    It has been more than 30 years since my grandfather made the first slip ring in our factory. Over the years we have developed more than 200 types of slip rings, widely used in agricultural machinery and automotive parts.

    What that means for you

    Three generations of hands-on tooling knowledge means we can read a worn slip ring, match it to an OE rotor, and quote the right replacement — or develop a new one when nothing off the shelf fits. Copper-alloy collector rings, machined and pressed in our own plant in Changzhou, China.

    • 30+ years of slip ring manufacturing
    • 200+ models in production, cross-referenced to CARGO, WAI, AS-PL, Bosch and Denso
    • 80% of output exported, to 80+ countries
    • 90 employees, SGS RoHS compliant, OEM and ODM welcome

    Talk to a person, not a form

    If you need slip rings — or want to develop a new one — please feel free to contact May directly. I am here to assist and provide optional solutions. Looking forward to the opportunity to work together.
