Flexible metal hose

The utility model discloses a flexible metal hose. An electrostatic plastic-blasting layer is arranged on the outer surface of the wall of the accordion pipe on the hose body and two connectors are respectively arranged on two ends of the hose body. The utility model adopts simplified plastic-blasting industrial art. With the effect of the electric field, charged resin equably adheres to the outer surface of the wall of accordion pipe and electrostatic plastic-blasting makes the coating smooth. And then the solidified resin is baked under high temperature and the resin thaws into a compact protecting layer and firmly adheres to the surface of workpieces. At last the resin is cooled. Compared with traditional lacquering industrial art, the utility model has the advantages that the surface is bright and smooth and the plastic-blasting layer has firm adhesive forces and mechanical strength which enhance the competitive power of the utility model.
