Since the rise of the COVID-19 virus, hands-free activation has been more important than ever, especially when it comes to hand washing. The touchless faucets produced by Quality Metal Finishing are cast, trimmed and machined in-house before the process of polishing and buffing to properly prep the parts. After preparation, the touchless faucets are sent through an automated master cycle to be electroplated in copper, nickel and chrome plating baths. This process creates a decorative chrome finish that is then tested for its thickness and esthetic purposes.
An unclear definition has led to an industry standard for classifying burrs.
Surface finish types for commercially supplied stainless steel sheet are detailed in various standards. ASTM A480-12 and EN10088-2 are two; BS 1449-2 (1983) is still available, although no longer active. These standards are very similar in that they define eight grades of surface finish for stainless steel. Grade 7 is “buff polished,” while the highest polish—the so-called mirror polish—is designated Grade 8
Precision shot peening brings an entirely new concept to the field of microabrasive blasting, and it is complementary to its larger cousin. Using glass bead media, several companies have been shot peening for years with microabrasive blasting technology.
