The TD Coating Centre is all about getting the highest performance out of your tooling, machine parts or other components. 

Starting in 2000 with just our Thermal Diffusion coating, the number of top-class wear and corrosion resistant coatings we offer to the market has grown in order to optimise parts to outperform and outlast. 

Our manufacturing division specialises in the supply of precision-ground (not only machined) tooling and parts from steels, tool steels or carbide, combining the essential ingredients of correct base material, heat treatment, surface finish and surface engineering for the best performance possible. We are a one-stop solution for ultimate performance!

 We currently apply the following coatings, surface treatments and services.

Deposition/Diffusion Coating

TD Coating – The Heavy-Duty, Toyota Diffusion VC coating. The standard for the highest performance, wear resistant standard surface coating on tools and dies.

Deposition Coating

PVD CoatingsThin, hard wear resistant coatings for high precision parts

  • CrN, TiN, TiAlN, TiAlCN, AlCrN, TiCN and CrN/CrC including Duplex version (shallow case pre-nitriding)
  • DLC (Diamond Like Carbon) – Super low friction coating (only available on items manufactured by TDCC).
Diffusion Treatments
  • Nitriding– Specialized Nitriding in which nitride layers are formed to match your application. Mould steel nitriding is used for a smooth, hard surface.
  • Diffox – Specialised Nitriding + black surface oxide for improved corrosion resistance
  • SCNSub Critical Nitriding forms a hard surface layer specifically on stainless steels and is done at a low temperature to maintain corrosion resistance
  • Boriding – Formation of very high hardness, low friction surfaces on mild steels, alloy steels and stainless steels
  • Anodizing –  for enhanced corrosion resistance of alu, hard anodizing for higher corrosion and wear resistance for Alu. 
Electroless Coatings
  • Electroless Nickel – high phosphorous, very good corrosion resistance and low friction. Can hardened for good wear resistance.
  • Electroless Nickel + Teflon – the added Teflon particles lowers friction and provides good release properties.
Surface Protection
Plated/Other Coatings
  • Flash Chrome – a thin chrome layer applied to finished parts; good wear resistance and low friction 
  • Hard chrome – thicker chrome layers applied by grind-chrome-grind specially for wear resistance
  • Polymer Sealant – sealant for chrome plated parts for improved corrosion protection and lower friction (“MLP”)

Can we make it for you

fang punchesWe don't just do coating. Tool steel and tungsten carbide custom tooling is also our game. If you need a complete solution, we will engineer a total solution for you from start to finish. Our speciality is fine ground small tools and components but we also supply Carbide blanks and preformed, as sintered tungsten carbide components as well. See our manufacturing page. Read more ...

Other Coatings & Technologies

We don't just do TD ! Titanium based PVD coatings, Armoloy, Resin bonded Ceramics and many other problem solving coatings. Over the years we have learned that one coating does not solve all applications. Take advantage of our experience to match the correct technology to your specific need.
