What is Metal Surface Finishing?

Metal Surface Finishing improves metallic product surfaces. It helps to make metals look better while achieving greater durability and superior performance levels. Three typical methods exist in the finishing process: mechanical, chemical and electrical. The selection of finishing methods depends on which metal material requires service.

Besides, the most commonly used metal finishing treatments are polishing, anodizing and electroplating. The finishing method produces shiny surfaces with a smooth texture on metals. For example, anodizing creates a safeguard coating that defends against corrosion damage. While electroplating creates a thin layer of metal to improve product strength. The appropriate finish selection depends on its designated use because each finish type delivers unique benefits.

Many production sectors implement surface-finishing processes in their manufacturing operations. Aerospace, automotive and electronic industries depend heavily on these finishing processes. Inadequate finishing methods cause parts to degrade prematurely until they break.

Why Surface Finishing Service Matters for Your Products?

A right finishing process transforms the entire outcome. Your product relies on a protective layer to resist wear and attacks from corrosion and harsh environmental situations. For instance, the automotive industry uses finishes to stop rust development and maintain part appearance. On the other hand, aerospace industries use finishes to make their components resistant to breakdowns while preserving their durability.

Choosing an inappropriate finish can lead to negative consequences. When using an inappropriate finish, your product will demonstrate accelerated corrosion and reduced lifespan. The product's safety standards and functional operation may be affected. Manufactured products that require food or medical device finishes benefit from these protective features because they signify product hygiene and cleanliness.

Moreover, the appearance of a product only scratches the surface of what surface finishing accomplishes. An optimum finish application ensures both product effectiveness and extended product lifespan. Therefore, achieving proper finishing demands absolute priority since it eliminates current and future issues that could lead to repair expenses.

Types of Metal Surface Finishing Services

When it comes to metal surface finishing, there’s no one-size-fits-all solution. Let’s discuss the standard metal surface finishes by identifying their singular characteristics.

  1. Anodizing

Anodizing functions through electrochemical treatment. It is commonly applied to aluminum parts surfaces. The production of a dense oxide layer through this process increases metal durability. The metal becomes less susceptible to corrosion after getting anodized. Such treatment makes metal surfaces more resistant to regular wear and tear.

The anodization technique adds no new materials to the surface as it differs from coating operations. The process intensifies the existing oxide layer of the metal material. Moreover, it shows better resistance to friction and needs minimal care. Such materials require this method because they face demanding environmental conditions.

Anodizing allows manufacturers to achieve attractive color finishes on their products. Dyes can be retained by the oxide layer, which does not compromise product durability. It finds its most suitable application within the aerospace sector and architectural industry. 

Aluminum-Anodizing

  1. Shot Blasting and Sandblasting

The cleaning operation of abrasive methods involves both shot blasting and sandblasting. The cleaning operation involving metal utilizes high-velocity particles in both methods. Shot blasting implements steel shots, yet sandblasting operates through sand utilization. The techniques eliminate rust and scale, along with old paint coatings.

Among its applications, shot blasting has been established to perform metal peening operations. Metal strength increases as it applies compressive stresses to the metal surfaces. It works best for surface preparation immediately before coating or painting applications. The adhesion strength of finishes increases when shot blasting is applied because of its effect on surface bonding.

The main purpose of sandblasting involves the preparation of metal surfaces. It develops effective surface cleaning and roughening with their operations. The improved bond between metal and coatings becomes possible via sandblasting. 

The construction sector extensively employs sandblasting and shot-blasting techniques. These techniques tend to enhance their vehicles as well as heavy equipment. Furthermore, these procedures allow coating designers to create surfaces ideal for receiving coatings.
