Abstract
A process of powder coating of workpieces in which initially a workpiece is coated with color powder such that the powder adheres to the workpiece and subsequently the powder is baked in an oven, in which subsequent to coating and prior to baking the powder adhering to the workpiece is irradiated with electromagnetic radiation within a particular, defined surface portion so that the powder within the defined surface portion will gelate and stick to the workpiece, and in which the color powder adhering to the workpiece outside of said defined surface portion is removed subsequent to irradiation.
Claims15
A process of powder coating of workpieces, comprising the steps of:
- coating a workpiece with powder so that the powder adheres to the workpiece;
- irradiating a defined surface portion of the workpiece with electromagnetic radiation to an extent such that powder particles of the powder within the defined surface portion stick together and stick to the workpiece;
- removing powder which adheres to the workpiece located outside the defined surface portion;
- and
- baking the workpiece in an oven.
A process of powder coating a workpiece comprising the steps of:
- coating a workpiece with electrostatically charged powder to cover a surface of the workpiece;
- irradiating a defined surface portion of the surface to an extent that powder particles of the powder present within the defined surface portion stick together and stick to the surface;
- and
- removing powder which adheres to the workpiece outside the defined surface portion.
