  • Patent number: 9139912
    Abstract: The present invention relates to a method and an apparatus by which powder is evenly dispersed and is coated on a substrate uniformly and continuously so that a uniform layer may be formed. More specifically the present invention provides a method and an apparatus for forming a coating layer that powder is coated on an entire surface of a substrate uniformly and continuously, regardless of the material or the size of the substrate, as a uniform amount of powder entrained on the carrier air which is generated by carrier air and powder transported to a carrier pipe at a certain rate is consistently fed in to a nozzle, regardless of the size, morphology, and specific weight of the powder particles.
    Type: Grant

  • Patent number: 9079209
    Abstract: The present invention relates to an apparatus which coats a substrate inside the vacuum chamber with the powder transported and entrained on the air from the outside without any extra gas supplier. Namely, the apparatus can coat the powder transported and entrained on the air naturally sucked in from the outside on a substrate through the spray nozzle inside the vacuum chamber as the pressure of the vacuum chamber is controlled and the pressure of the front of the spray nozzle is set under the atmospheric pressure.
