BELL CUP AND SHAPING AIR RECHNOLOGY - Bell Cup and Shaping Air Technology are advanced techniques used in the field of spray painting, particularly in the application of coatings in automotive and industrial sectors. These technologies are crucial for achieving high-quality, efficient, and precise paint application. Here's a detailed look into these technologies: How It Works 1. Rotating Bell Cup: - The bell cup spins at high speeds (up to 60, 000 RPM or more), creating centrifugal force. - Paint is delivered to the center of the rotating cup, where it spreads outward to the rim due to centrifugal force. 2. Paint Atomization: - As the paint reaches the edge of the cup, it is atomized into a fine mist. - The size of the droplets can be controlled by adjusting the speed of the bell cup and the flow rate of the paint. 3. Electrostatic Charge: - In many systems, the paint droplets are given an electrostatic charge. - This charge helps attract the droplets to the grounded object being painted, increasing transfer efficiency and reducing overspray.
