The team at General Metal Finishing has been providing premium plating services for over 50 years, offering options for gold plating, silver plating, tin plating, tin-lead plating, electrolytic nickel, and electroless nickel.
Along with these services, we can also deliver metal part electropolishing to improve component appearance and create a smoother, cleaner finish. Read on to learn about our approach.
About Metal Electropolishing
Electropolishing is an electrochemical process designed to enhance the surface layer of metal parts, particularly stainless steel and other alloys. During the process, a thin layer of the component’s material is removed, resulting in a much smoother and cleaner finish for the piece.
Microscopic imperfections, burrs, and contaminants are all removed during what has been called a reverse plating process, as the part or workpiece is immersed in an electrolyte bath that features an electrical current.
Advantages of Metal Part Electropolishing
Customers that invest in electropolishing services can benefit by way of:
- Shinier, more aesthetically pleasing parts and products
- Removal of contaminants and small defects
- Dissolving of free iron, inclusions, and particles
- Creating a more carbon-rich surface on stainless steel substrates
- Increased corrosion resistance and likelihood of cracking
- Reduced friction when parts work in conjunction with other components
- Easier cleaning of parts
- Reduction in the buildup of bacteria
- Enhanced durability and longevity of components
- Uniform surfaces, since only a chemical bath is used rather than machining
- No-contact approach, avoiding directional polishing lines
- Suitability for delicate parts when tumbling, vibrating, and grinding approaches would create issues
- Electropolishing is the best form of passivation
All of these attributes make machined stamped part electropolishing ideal for fields like food processing, aerospace, medical device production, and more, which require clean and sterile surfaces for their operations. We offer electropolishing on both aluminum and stainless steel substrates.
