Electrostatic coating
CFT Ransburg offers you an ideal coating system
The work piece to be coated is attached to a positive electrode (grounded) and an applicator is attached to the negative electrode. In this coating technology a high voltage supply is utilized to create an electrostatic field between the two electrodes. Atomized particles of paint, receiving a negative charge, are attracted rapidly and evenly to all areas of the positively charged work piece, even to the sides and the rear. The advantages of this electrostatic coating technology are that it not only saves a large amount of coating material, but also results in a reduction in the coating time through the improvement of coating capacity. Material savings, protecting the working environment and also bringing us high added value as a technology for safeguarding the natural environmental - these are the reasons why the electrostatic coating process, an innovative technology, is widely chosen.

Electrostatic coating
The electrical field between the ionizing needle and the grounded object helps drive the charged spray particles to the grounded target. The force of the electrostatic field cause a greater percentage of the charged spray particles to reach the grounded object, rather than miss the target or be swept away by surrounding air flow.
1.Ionization at the point-end of the gun
2.Paint particles are negatively charged
3.Negatively charged paint articles are attracted to the work piece
