RMB26 | Bell Type Coating Applicator with High Transfer Efficiency
Realizes Electrostatic Coating in proximity to workpiece.
Features
- Realizes High Transfer Efficiency
- A newly developed high-voltage controller controls current and voltage values at high speed to ensure electrostatic coating while maintaining safety.(Patented)
*The new CB (Current Buffer) curve function prevents overcurrent and greatly reduces line stoppages due to high voltage abnormalities.
*The actual coating efficiency is greatly improved by maintaining proper electrostatic effect even when the coating machine is close to the workpiece. - A newly developed cascade built into the bell provides a quick response to high voltages that was previously impossible. (Patented)
- By responding sensitively to minute changes in current, it avoids thick film on convex areas and thin film on concave areas to achieve a uniform finish, even on complexly shaped workpieces.
- A newly developed high-voltage controller controls current and voltage values at high speed to ensure electrostatic coating while maintaining safety.(Patented)
- Conventional Coating and Proximity Coating can be Realized with a Single Bell
- The distance between the coating machine and the object to be coated can range from 50 mm to 250㎜ and depending on the shape of the object to be coated, either conventional coating or proximity coating can be selected.
- In the case of proximity coating, its theoretical coating efficiency is 100%. Actual coating efficiency for various shapes is expected to improve by 15% to 20% compared to conventional coating. (Our laboratory results)
- Supports various coating conditions
- Metallic painting by proximity coating is also available.
*High transfer efficiency prevents aluminum fragments in the metallic paint from scattering, resulting in a high-brightness finish. - A wide variety of shaping air rings and bell cups are available to select an application pattern that meets the finish requirements.
- Metallic painting by proximity coating is also available.
- Cost Reduction
- High transfer efficiency contributes to the reduction of paint usage, touch-up works, waste disposal, maintenance costs such as cleaning of painting facilities.
- Initial costs, operating costs, and equipment maintenance and management costs in the coating process can be widely reduced.

Functional safety
Conventional electrostatic coating was used only at long distances where high voltage is stable, but the new high-speed control system (CB curve) enables high coating efficiency and high brightness while preventing thick film on edge coated objects such as near coating and V-shape.
