Metal finishing is an important manufacturing process, providing either aesthetic appeal or increased life and durability of a part. Understanding the distinction helps ensure the right finish is selected for each application.
What Is Functional Metal Finishing
There are many different types of finishes that can be applied to a part after machining to add value to the part. These finishes are often referred to as “functional finishes” and can provide properties such as corrosion resistance, wear resistance and environmental resistance. Functional finishes are critical to the performance and life of a part and are used in many industries including aerospace, medical, automotive and many others.
Processes using electroless nickel plating are commonly used to strengthen surfaces and extend service life. By forming a protective layer, they help prevent deterioration and reduce maintenance needs. More detailed examples can be found through specialists such as //www.swmf.co.uk/surface-coatings/electroless-nickel-plating, which outline typical applications across different sectors.
What Is Decorative Metal Finishing
The purpose of decorative finishing is to enhance the appearance of a finished product. This can involve colour, texture and image, and a range of processes such as polishing, coating and plating are used to achieve a specific look. These finishes are commonly used and are very prevalent in the market place with a wide variety of applications, including domestic articles and automotive components.
Choosing the Right Approach
A functional coating would be suitable for parts which are subject to heavy stress and frequent use. For parts that are to be exposed, an enhancement to the part’s decorative value would be appropriate.
