The customer would like to add a patina to the raw zinc castings. Currently, they are using copper sulfate and machine polishing to achieve the desired finish. We would like to tumble, or find a more automated process to finish the pieces.

If you are unsure what equipment and media you require to achieve your desired surface finish, then send us your part, and we will evaluate it and provide you with a metrology report.
