Since 1988, we’ve been helping businesses create, innovate, and excel within their industries by manufacturing top-quality power cords and providing custom electronics manufacturing services. Formerly known as Tumbler Corporation dba Ching Cheng Wire Materials, the transition into Linvox Corporation represents a new chapter in our company’s history as a power cord manufacturer and supplier. As organizations strive to innovate in a world that’s “always on” and constantly connected, they need a reliable partner that can design, manufacture, and deliver world-class energy solutions. A custom cable manufacturer is what they need.
