Surface finishing and food-contact compliance

Powder coating, chrome plating and electropolishing — plus the food-contact testing route that decides which finishes are acceptable in which market.

Process steps

  1. 01Pre-treatment (degrease, pickling, rinse)
  2. 02Powder coating or electroplating
  3. 03Cure / passivation
  4. 04Appearance and adhesion check
  5. 05Salt-spray and food-contact sampling as required

Process data

Powder coating
Any RAL tone, matte or gloss
Plating
Chrome, nickel
Salt-spray performance
TBD — confirm with engineering
Food-contact testing
Third-party, per destination market
Comparison of chrome-plated, electropolished and powder-coated wire samples

Finish is not a cosmetic choice. On a kitchen product it determines which markets you can sell into, because food-contact regulations restrict what may come into contact with food.

Finish and market are linked

Market Food-contact route Effect on finish
North America FDA 21 CFR Coating and plating must be on the accepted list
European Union EU 1935/2004 Migrations limits apply per material
Germany LFGB additionally Stricter migration testing in practice

This is why we ask for the destination market before tooling: a finish that is fine for one market may require retesting for another.
