Multiple industries rely on the process of metal finishing producing products that are practical, aesthetically pleasing and without any burrs or defects. Across the computer, aerospace and electrical markets, you will encounter countless examples of parts or items that use metal finishing.
How metal finishing works
The metal finishing method is the end of the manufacturing process of metal parts or products. The technique involves applying a special coating to the surface of the metal. The primary purpose of metal finishing is to provide the metal with a protective layer to give it the durability required to perform the way it was designed to function. Metal finishing also aids safety in metal products by removing sharp edges or corners through various methods. Metal finishing techniques also increase the visual appeal of metal. It can obscure welds and smooth off corners or depending on the intended use, brush the metal for a stylish effect or polish it to create a sparkling reflective surface.
The different methods of metal finishing
There are around eight primary methods of finishing metal, and which one you use will depend on the type of metal and its purpose. These include:
