US 9,895,709 B2 · Thermal spraying system

Abstract

A thermal spraying system includes a fixing device and a thermal spraying apparatus that are relatively movable. The thermal spraying apparatus includes a hollow pipe, an extrusion die, a transporting device, a helical pipe, a fluid supplying device, and a heater. The hollow pipe defines an accommodating space. The extrusion die is connected with the hollow pipe. The extrusion die has a nozzle. The nozzle is in spatial communication with the accommodating space. The transporting device is used for moving a raw material to pass through the nozzle. The hollow pipe is surrounded by the helical pipe. An end of the helical pipe is connected to the nozzle. The fluid supplying device is connected to another end of the helical pipe. The heater encloses the helical pipe and the hollow pipe for heating the helical pipe and the accommodating space.
