  • Bell cup of rotary atomization type coating device
    Patent number: 10722908
    Abstract: A bell cup (3) of a rotary atomization-type coating device (1) is provided. This device has a rotary shaft (13) and a feed tube (15) inserted in the rotary shaft. The bell cup is fitted to a tip end part of the rotary shaft and has a coating material spreading surface (31) on an inner surface of the bell cup. The feed tube discharges a coating material to the coating material spreading surface. The coating material spreading surface includes a region extending from a predetermined position on a proximal end side to a distal end edge. The region is constituted of a convex curved surface toward an extension of the rotary shaft. The outermost surface of at least part (31B) of the coating material spreading surface is covered by a diamond-like carbon film (50) free from silicon at least on its outermost surface.
    Type: Grant
