The Swiss company SFB AG, a subsidiary of e. Luterbach AG, is specialized in innovative painting systems, including high capacity powder coating lines. Today over 1 billion small parts each year will be powder coated on all sides without any hangers. This is accomplished by the employment of special transport, coating and curing technique.
On this process, the small parts (part sizes: 10-80mm) are manually or automatically positioned on a flat conveyor, powder coated on one side, and after curing automatically turned and then coated on the other side at a line speed of up to 2 meters per minute and a bandwith of up to 800 mm. The result is an extremely high capacity of up to 20’000 pieced per hour. Worldwide, over 20 of such powder coating lines are in operation.
Please watch the video for the powder coating of wheel weights. The wheel weights are positioned on a flat conveyor, powder coated on one side, and after curing automatically turned and then coated on the other side.
