Why Us

Seidel Aluminum Anodizing Company
Choose Seidel and you’ve picked the best electro-polishing and aluminum anodizing company in the country. We're proud of our innovation, high quality and customer satisfaction. In our state of the art facility we continuously train our team with the Lean Thinking Philosophy and stress continual improvement. 
Our finishes and colors are customer specific. If you can imagine your aluminum part in a different finish or color, we can make it happen. Just send us your part and we will create some new looks for you. Contact us now.


Our proximity to the cosmetic industry and great relationship with local raw part manufacturers insures fast turn around of samples for color and dimensions.

For color matches we invite the end customers of the cosmetic industry into our lab and production facility: that can reduce the traditional time for color approval dramatically.

Electropolishing for Automotive Parts

Environmental Advantage

  • Seidel’s Electro-polishing versus traditional chemical brightening:
             No Copper additives => no heavy metal in waste
             water and filter press cake
             No hot nitric acid added like in bright dip tank => no
             fumes in exhaust air
  • Proprietary hot water seal without nickel as in the traditional Nickel Acetate seal =>   no nickel in waste water and filter press cake

We work exclusively with aluminum, which is a prime material for recycling. Aluminum can be recycled indefinitely without any loss of quality and uses only a fraction of the original energy for the recycling process.

              Electropolishing for any color, any finish, any decoration.

              Continuous improvement through R&D

              • First to develop slip seal and ultra slip seal for dramatically reduced marring and reduction of scratches from one part damaging the next in bulk shipments.
              • Interference coloring for multi colors on the parts
              • Pearlecsence finish with Seidel’s proprietary “Alu-Pearl”
              • Experimenting with random multi color patterns
