Overview
- 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.
-
Safety features have been greatly improved.
Conventional electrostatic coating is used only at long distances where high voltage is stable, but the new high-speed control system (CB curve) has made it possible to achieve high coating efficiency and high brightness while preventing proximity coating and thickening of V-shaped edge coatings.
