Anodizing Clinic: Measuring Color of Coatings with a Colorimeter
Q. Recently, a company asked us to match its samples so we could do work for them. According to our method, we matched the samples, but they were rejected when they were sent to the company. We were told the samples were out of tolerance. We discovered the company used a different brand colorimeter with a different color scale to measure the color. Is there a set standard in the anodizing industry for measuring and matching colors?

Anodizing Clinic: Anodic Coating Blistering on 7075 Alloy
Q. We have recently run into a surface condition when hard anodizing 7075 machined forgings. It seems to be present primarily on the end of the part, even down into the hole. Both of these areas are machined. The condition does not appear to be evident on other surfaces. I have not seen this condition before, but it appears to me to be rather unique and something recognizable.

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: Powder in Layers
Q. We are in the process of designing a new powder system for aluminum extrusions and building panels. Our current system uses a six-stage dip pretreatment process and a three-layer liquid paint process (prime, color coat, clear coat) that meets AAMA 2605 standards (American Architectural Manufacturers Association). What layers of coating should we use and can we can meet the AAMA 2605 standards with powder?

Powder Coating Clinic: Making Powder Lines More Profitable
Q. We run a job shop powder coating operation with a conveyor system that runs at around 4 to 6 fpm, depending on what product is hung. We are putting through a lot of work, but our profits are not great. Can you suggest how to improve the efficiency, or cut our cost for a better profit margin? 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?
