Abstract
This paper proposes a method of designing the main parameters of the Teflon coating equipment of a guide wire used in medical treatment. The proposed device was designed to be guided by a reel-to-reel method in which the guide wire performs all processes continuously, such as Teflon coating and heat treatment. At this time, the conveyed guide wire vibrates between the rollers, which affects the quality of the coating. Therefore, this paper proposes a dynamic equation of the guide wire to be transported in the longitudinal direction, and design parameters setting method of the feed speed and the interval of the roller supporting the wire is proposed to minimize the vibration amplitude of the guide wire during transport. The Teflon coating of the medical guide wire was carried out based on the developed coating equipment. The target coating thickness of the guide wire was set to less than $10{\mu}m$ in the circumferential direction, and the results were examined by optical microscopy.
