Electropolishing Services for Precision Metal Finishing
Contact Us Today!
Electropolishing enhances metal surfaces by removing imperfections and improving corrosion resistance. Our precision process ensures high-quality results for metal surfaces like 304, 316, and 400 series stainless steel and alloys.
Unlike traditional methods such as grinding or buffing, electropolishing uses electrochemistry to achieve a polished surface. The metal object is immersed in an electrolyte solution and subjected to a direct electrical current, which removes surface contaminants and enhances cleanliness.
What can be Electropolished?
HPT can work with you to evaluate your project and determine which parts and pieces you should electropolish. All material will be electropolished using industry standards, inspected by trained personnel, and packaged in our class 10,000 cleanroom.
Electropolish the following Components, Parts & Systems:
- Tube, Fittings, Pipe and Pipe Fittings
- Tanks
- Racks, carts, and tables
- Pumps, flanges, etc.
All material electropolished receives a certification of conformance after processing.
HPT can also perform electropolishing services with expedited lead times to prevent downtime in your system or project.
Key Benefits of Electropolishing
- Corrosion Resistance: Protects against rust and oxidation Smooth
- Mirror-Like Finish: Reduces surface roughness for aesthetic and functional benefits
- Deburring & Edge Rounding: Removes microscopic burrs, preventing premature wear
- Passivation Enhancement: Creates a more uniform passive layer for increased longevity
Frequently Asked Questions
What is Electropolishing?
Electropolishing removes surface contaminants and micro-roughness, improves corrosion resistance and enhances appearance and smoothness.
How does electropolishing differ from mechanical polishing?
Electropolishing is an electrochemical process that removes metal ions for a smooth, clean finish, while mechanical polishing relies on grinding or buffing, which can leave scratches or debris. Electropolishing offers better precision, cleanliness, and corrosion resistance.
What industries benefit the most from electropolishing?
Industries that benefit most from electropolishing include medical, pharmaceutical, food and beverage, aerospace, and semiconductor sectors. These industries require smooth, clean, and corrosion-resistant metal surfaces for improved performance and hygiene.
Does HPT-100 Specifications Meet ASTM B912-02 Standards?
Our electropolishing service follows the HPT-100 specification, meeting ASTM B912-02 standards or customized requirements based on customer needs. Compliance with ASTM, ISO, and industry-specific standards
Are the components inspected and bagged after being electropolishing?
All components, parts & systems will be electropolished to HPT-100 specification, inspected, bagged and labeled and certified.
