What manufacturing design engineers need to know about product finishing and specifications
Custom coaters work hand in hand with metal manufacturers to provide compliant finishes to products that are used in diverse markets that range from toys to building structures and beyond. As products vary, so do the finishing requirements that make up the total value-added qualities that the consumer has come to expect. Unfortunately, many designers and engineers fail to properly address the requirements of the performance and decorative value of the final finish in terms of technical information. This seems to be a growing problem in the finishing industry.
Manufacturing prints typically make for a poor baseline for finishers to estimate job cost, provide accurate bid contracts, and offer advice regarding details of the finish and finishing processes that may indeed provide superior value to the product. A typical part drawing or print layout will address all of the important details required to manufacture a part. Rarely is there any useful information on the print drawing regarding the details of the finishing requirements and expectations of the finish in terms of decorative or protective values. The print layout can, however, become a useful tool in communicating the finishing requirements if the design engineers care to include this information on the print drawings.
