Small component e.g. bolt, coating device for changing e.g. electrical and optical surface properties of workpiece, has infrared-radiant heater, fastening device and sensor for heating, dehumidifying and hardening coating material

摘要

The device has a drum (1) displaceable in rotation, and receiving and recirculating small components (3). A spraying gun (4) and a fastening device (5) apply a coating material on the small components in the interior of the drum. An infrared-radiant heater (6), a fastening device (7) and a sensor (8) are provided for heating, dehumidifying and hardening the material that is applied on the small components in the interior of the drum.
