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.

What can cause color variation from part to part? How can we balance the oven and stop this problem?

We cannot speed up the line because we do not have enough time in the cure oven to go faster. Our powder material cost seems to be higher than what we expect based on our quotes. What are we missing?
