A powder resin coating device and method that can make the powder surface of powder resin within a powder fluidizing bed flat without spattering. The powder resin coating device includes: a powder fluidizing bed storing powder resin; a vibration mechanism connected to a bottom surface of the powder fluidizing bed; and a support member connecting the powder fluidizing bed and a fixing surface. The vibration mechanism includes: a vibration unit, and a connection mechanism connecting the vibration unit and bottom surface of the powder fluidizing bed. The support member elastically supports the powder fluidizing bed to the fixing surface and is mounted more inwards in a radial direction than an edge part of the powder fluidizing bed. The vibration unit is connected to the bottom surface via the connection mechanism so that a vibration motor rotations shaft is substantially coaxial with an axis of the powder fluidizing bed.

An apparatus for coating an object or component includes at least one dispenser for dispensing a falling flow of material and an actuator for projecting the component through the falling flow of material. A landing may also be provided for receiving the coated projectile, the landing adapted for providing a second coating to the coated projectile. Related methods are also disclosed.
