Metal finishing involves a set of chemical and mechanical processes that can improve durability and appearance in metal surfaces, as well as resistance to corrosion. Metal finishing is critical for components across a range of industries, including automotive, aerospace, food processing, construction, oil and gas, and medical. Some of the potential metal finishes include polishing, abrasive blasting, powder coating, zinc plating, and polishing, along with pre-treatment.<\/p>\n
The end result is a surface that benefits from increased corrosion resistance, cleanliness, wear resistance, visual appeal, and the ability to meet certain industry requirements.<\/p>\n
Many surfaces need corrosion resistance to prevent oxidation and eventual rusting that could otherwise result from exposure to environmental factors. The right finish can also protect surfaces from abrasion and friction damage, especially among load-bearing and moving components.<\/p>\n
Polished stainless steel surfaces are easier to clean and sanitize, which is essential in medical and food-grade components that might otherwise risk contamination. Additionally, some finishes come with specific functional benefits, such as heat resistance or electrical conductivity.<\/p>\n
Depending on the application, there are multiple metal finishing processes you may use, ranging from abrasive blasting to polishing and stainless steel passivation.<\/p>\n
Abrasive blasting, also known as sandblasting, is ideal for removing paint, rust, scale, and various contaminants and can prepare the surface for further coating. Many types of abrasive media can be used in this process, such as:<\/p>\n
This process also works with different materials, including stainless steel, certain alloys, aluminum, concrete, and titanium.<\/p>\n
This chemical process is used to remove contaminants and free iron from the surface of stainless steel components. In doing so, passivation gradually restores the material’s chromium oxide layer for increased corrosion resistance. Various testing methods can be used for quality assurance, including:<\/p>\n
Passivation is used with varying metal materials, from precipitation-hardened stainless steels to titanium and exotic alloys.<\/p>\n
Polishing works to refine surfaces using a mechanical process that optimizes the material’s corrosion resistance and hygiene while improving aesthetics. Surface conditioning includes pre-treatment processes like vapor degreasing, chemical descaling, ultrasonic cleaning, and pickling. Polishing is particularly important in applications that prioritize surface smoothness and sanitation.<\/p>\n
The surface material will largely dictate which process is right for your application, with passivation working best for stainless steel and anodizing being better suited for aluminum surfaces. You must also consider performance requirements for parts, including wear resistance, corrosion resistance, visual finish, and hygiene.<\/p>\n
In addition, some environmental factors could influence the process choice, such as temperatures, chemicals, and moisture. The process you select should help meet relevant industry standards. Production requirements are also important to consider, including the geometry, size, quantity, and turnaround time needed for parts.<\/p>\n
