Description

Located in a room on the southern wall of the Metal Shop, between the sand-blasting room and the CNC plasma cutter. This facility is sized to accommodate bicycle frames. A rolling rack holds the workpieces in an 8'x8'x8' spray booth and then transfers to a 4'x4'x8' box oven. Two guns are available, and many jars of colored paints are present in the shop. The spray booth is vented inside the room after filtering the airflow.

The process uses dry powdered paint that is applied with a pneumatic gun that includes a high-voltage electrode. As the powder passes by the electrode it becomes electrically charged. The metallic workpiece is grounded and so it attracts the charged paint particles. After coating, workpieces are baked in a convection oven to fuse the paint.

Films made by powder coating are up to ten times more durable than those made with liquid paint. The coatings are essentially fused plastic, and so they resist chemicals and salt exceptionally well. Further, the process produces no organic fumes or toxic waste.
