Specialised Processes

Special Finishing

Special finishing covers non-standard finishing operations arranged to a specific requirement, such as electropolishing, chemical deburring, superfinishing, pickling, cleanroom cleaning or custom texture finishes. We find the right specialist for requirements outside everyday processes.

What it is

Electropolishing smooths and brightens stainless steel by removing a thin surface layer electrochemically, improving cleanability and corrosion resistance. Pickling removes weld scale and heat tint. Precision cleaning prepares parts for vacuum, oxygen or medical use.

Where a drawing calls for an unusual finish, we source a qualified process partner and verify the result against the specification.

Typical applications

  • Pharma and food stainless equipment (electropolishing)
  • Weld scale removal (pickling)
  • Oxygen and vacuum service cleaning
  • Custom textures and cosmetic finishes
  • Special deburring of internal passages

Suitable materials

  • Stainless steel
  • Aluminium
  • Titanium
  • Copper alloys
  • Steels

Points to consider

  • Share the specification or standard the finish must meet.
  • Electropolishing removes a few microns; allow for it on tight fits.
  • Cleanliness requirements need suitable packing after finishing.
  • Sample approval is recommended for cosmetic finishes.

Frequently asked questions

What is electropolishing?

An electrochemical process that removes a thin layer from stainless steel, leaving a smooth, bright, easy-to-clean surface with improved corrosion resistance.

What is pickling of stainless steel?

Chemical removal of weld scale, heat tint and contamination, usually followed by passivation.

Can you arrange unusual finishes?

Yes. Share the specification and we will source a qualified process partner and verify the result.
