ABSTRACT:
A coating method includes rotatably supporting both ends of the piston or product to be coated; injecting coating material to a first parts of the piston or product to be coated through a first nozzle while rotating the piston, and simultaneously spreading to a uniform film thickness the coating material applied to the first part of the piston or product to be coated thereby removing excess coating material; fixedly supporting both ends of the piston or product to be coated; injecting coating material to a second pad of the piston or product to be coated through a second nozzle while sliding the second nozzle in an axial direction of the piston or product to be coated, and simultaneously spreading to a uniform film thickness the coating material applied to the second part of the piston or product to be coated thereby removing excess coating material.
