How to ensure consistent coloring in mass production? Paint one color at a time before moving to the Next

In the article How to Ensure Consistent Painting Colors in Mass Production? Do Not Separate Production Process, we explained how we ensure consistent painting colors and how we reduce significant color discrepancies, avoiding cases where some products are painted bright red while others end up in dark red.

Another common question we often receive is: When mass production, how do we ensure that the same parts on all products are painted with the exact same color?

The answer is: After completing one color, we only move on to paint the next color.

Here’s an example from production:

To produce the Husky magnet shown in the photo on the right, in a batch of 1,000 pieces:

In the early production stages, molds are created, slurry is poured, and trimming is completed. Once we confirm that the white bodies are well-prepared and ready for painting, we proceed with painting 1,000 pieces.

First, we paint the eyes of all the pieces, completing 1,000 pairs of eyes before moving to the next color.

The next color to paint is the fur. After painting the fur on all 1,000 pieces, we don’t move on to any other color until this step is fully finished.

We follow this process—completing one color at a time for the entire batch before moving on to the next.

Many clients assume that we paint one piece fully before moving on to the next piece. However, if we were to follow this method, there would be significant color variations across the products, and the painting staff might easily mix up painting positions, miss a color, or apply inconsistent color depth.

By adopting our method of “same item, same factory, same batch of paint, few people for painting”, we maintain both painting quality and production efficiency.
