Chemical Blacking

New for 2008 Wallwork Heat Treatment have added another process to their existing high quality heat treatment and coatings portfolio. Located at the Birmingham branch, Wallwork have invested in a fully automated, computerised Chemical Blacking conversion treatment plant. The chemical blacking process imparts a decorative black corrosion resistant finish on most ferrous surfaces without altering the component dimentionally.

Advantages:
  • No dimentional change: many machined parts are manufactured to tight tolerances, which means plating or painting is not acceptable.
  • Corrosion resistance: The black surface absorbs wax, oil or rust preventative sealants to givecorrosion protection.
  • Sales appeal: A durable black finish enhances the appearance and value of a wide range of manufactured articles.
  • Safety: By reducing the light glare from moving tooling or machinery, it eases fatigue and contributes to operator safety
