It is a company subordinated to and held by Jinggong Group. It engages in the production manufacturing of composites and carbon fibers, the design, manufacture and installation of the water treatment equipment. Carbon fiber automatic winding device is suitable for carbon fibers and other fibers. The device can winding for fixed length, fixed diameter and fixed weight, in addition have the function of automatic wire winding, less carbon fiber loss, better winding forming effect. Digital integration can constant winding ratio to ensure stability tension and molding effect. Carbon fiber precursor automatic unwinding device is suitable for the constant tension wiring and digital integrated controlled of PAN fibers and other fibers.
