How Magnetic Induction Method Measure Powder Coating Thickness

September 6, 2019

Although powder coating guns meticulously apply thin films of air-driven particles, that feature is rarely blindly accepted. Certainly, if the company in question is targeting a quality-assurance certification, they're not just going to coat a workpiece and send it straight to the curing oven, no questions asked. No, as part of that QA program, the protective sheathing has to be thickness-audited, and this skin verification check must be professionally conducted.

Overcoming the Faraday Cage Effect in Powder Coating Application

August 22, 2019

Tied to the powder coating process, The Faraday cage effect takes place inside confined workpiece areas. The electrostatic fields flow, as the laws of physics command, but a seemingly invisible barrier degrades those forces as they move into a part's corner or recess. And, since the powder follows the path of those lines of charged energy, the tiny capsules can't help but treat these recesses as no-go areas. That's a problem.

The Significance of Particle Size in Powder Coating Transfer Efficiency

August 6, 2019

Looking deep, coating particles are clearly incredibly fine. They're discharged from an electrostatic gun, driven forward by compressed air, then there's a split-second of airborne drift. At this point, a workpiece with an opposing charge attracts the tiny pigment-loaded grains.

The Differences Between Powder Coating and Electroplating

July 18, 2019

Electrostatic fields attract air-carried charged powders until a uniformly coated layer blankets an oppositely charged workpiece. That, in a nutshell, is how powder coating works. Now, electroplating might seem like a similar coating system, but it's really an entirely different process. Right off the bat, plating is done in a wet bath. Powder coating is a dry process. That's a pretty significant difference, and there are others.

Powder Coat Adhesion Testing Process

July 4, 2019

Just to clarify matters, there are ways of testing powder coat adhesion strength. That fact may come as something of a surprise, especially when you remember just how hard it is to part a baked-in coating from its surface, but there are test procedures that are designed to get around such challenges. Fused to a workpiece or not, the testing process measures adhesion integrity most effectively.

What are the Causes of Outgassing in Powder Coating?

May 1, 2019

Outgassing incidents make process managers feel as if they're living on their last nerve. The curing oven has perfectly fluidized the powder, and those tiny particles are uniformly covering a complex piece of metal-based geometry.

Powder Coating Gun Settings: How It Can Affect Powder Coat Finish

January 31, 2019

Where's the fingertip controlled leading edge of a powder coating operation located? Does it take place at the oven, where the adhering powder melts? No, although the temperature controlled oven does contribute heavily as a coating quality conferrer, it doesn't actually apply the powder coating.
