Powder Coating Clinic: Solving Problems with Color Variation
Q. We are noticing differences in the color of parts coming out of the oven. It seems to happen more on some days than others. It can happen with any of our brighter colors like orange and red but does not seem to happen with more neutral colors like tan or gray. We use some infrared heaters in the first 20 feet of the oven and the rest is convection heating. We worked on balancing the oven but it is hard to get it level all the way through. What can cause color variation from part to part? How can we balance the oven and stop this problem?
Powder Coating Clinic: Oil Seeping out of Large Welded Tubing
Q. We have a large part made out of tubing that is welded together. The tubing has a lot of oil seeping out of the welds when the part is heated and causes a defect in the cured film. We cannot get the oil out of the tubing in our washer. We tried cleaning up the defect and running it again, but oil still runs out. How can we get that oil out of the tubing?
Powder Coating Clinic: Touch-up Options for Powder Coated Parts
Q. I’ve been told that a powder coated part cannot be “touched-up.” I have some patio furniture that I had powder coated and the powder coating shop that did the work for me stripped the threads in holes used to rack the part. I can fix the threads by welding up the hole and re-taping the threads. The shop states the whole piece will need to be redone and they cannot address just the small area affected by the repair. Is this accurate? Is it true that powder coating cannot be touched up?
