Abstract
Provided is an apparatus for powder coating 1 which includes a coat-applying station 39 for applying a powder coating P on a work 3 to be coated, and a high frequency induction heating apparatus 47 for heating the work 3 covered with the powder coating P under the effect of high frequency wave and baking the powder coating P on the work at the interface defined between the powder coating and the work. Use of the apparatus 1 provides a uniform and strong coating film without any unevenness more efficiently with the relatively compact apparatus.
Claims8
An apparatus for powder coating of high frequency induction heating type comprising:
- a coat-applying station for applying a powder coating on a surface of a work to be coated by electrostatic painting
- a heating station for baking the applied powder coating, including a pair of high frequency induction coils arranged opposite to and apart from each other, which, upon supply of heat frequency wave current, heat the work covered with the powder coating, thus proceeding baking of the powder coating from the work side,
- a hanger including a plurality of hook-mounting bars on which hooks are mounted, and being made of a material to which no heating influence of high frequency wave current can be incurred, and
- a hanger transfer means for transferring the hanger sequentially to each of the process stations, the hanger transfer means guiding the hanger between the opposite high frequency induction coils.
