Switch to Custom-Molded Masks
If your paint line is going through a high production run of a part, we can't stress enough the benefits of switching to custom-molded masking. Typically, using custom silicone masks can shorten your masking process from minutes to just seconds as most are designed to be placed on the part, and ready to go.
A great example is shown here with a brake caliper. If you've never seen someone try to mask as brake caliper with just green poly tape, it's quite the task. A ton of time and effort has to be put into a part like this. Fortunately, with a custom-molded mask, brake caliper coaters can reduce their masking operations times to a fraction of what it was.
