Electrostatic painting was first patented in the U.S. by Harold Ransburg in the late 1940s. Harold Ransburg founded Ransburg Electrostatic Equipment and discovered that electrostatic spray painting was an immediate success as manufacturers quickly perceived the substantial materials savings that could be achieved.
Electrostatic coating is a manufacturing process that employs charged particles to more efficiently paint a workpiece. Paint, in the form of either powdered particles or atomized liquid, is initially projected towards a conductive workpiece using normal spraying methods, and is then accelerated toward the work piece by a powerful electrostatic charge.
A rotary atomizer is an automatic electrostatic paint applicator used in high volume, automatic production painting environments. Also called a 'paint bell', "rotary bell atomizer" or 'bell applicator', it is preferred for high volume paint application for its superior transfer efficiency, spray pattern consistency, and low compressed air consumption, when compared to a paint spray gun.
Gema Switzerland GmbH is a leading supplier in the area of electrostatic powder coating with a worldwide presence. From simple hand coating through to fully automated powder coating, this Swiss company offers solutions that meet the high demands and requirements of customers around the world in a wide range of industrial sectors.
A rotary atomizer is mounted to a paint robot or a reciprocator. Often call a Rotary bell atomizer, this paint applicator is often paired with electrostatic technology in order to maximize transfer efficiency of the paint. Rotary atomizers spin at extremely high speeds to break up the paint into fine, even particle sizes.
Russell Gray, a Minneapolis parking lot attendant, founded Gray Company, Inc. in 1926 with his brother Leil Gray to produce and sell Russell's air-powered grease gun, invented in response to cold weather making hand-powered grease guns inoperable. [3] Sales their first year of operation were $35,000. [3] By 1941, annual sales had reached $1 ...
Example of powder coating spray guns. The most common way of applying the powder coating to metal objects is to spray the powder using an electrostatic gun, or corona gun. The gun imparts a negative charge to the powder, which is then sprayed towards the grounded object by mechanical or compressed air spraying and then accelerated toward the ...
