Uncovering Plating Defects: Understanding how Metallographic Techniques (with examples) Help Die Casters Determine the Real Root Causes of Plating Defects

摘要

Die casting companies that manufacture plated product are faced with a high level of complexity and quality. The die casting surfaces must be free of defects such as cold shuts, surface porosity, lakes, etc... The castings need to be cleaned, rinsed, activated, and plated with a series of chemicals and solutions to produce a highly aesthetic appearance. In short, plating involves a variety of potential processes that can cause defects related to the plated surface.
