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. Still the most wear resistant standard other’s strive to achieve.

Deposition Coating

PVD Coatings

  • TiN – durable, high hardness, used on metalforming dies and injection moulding parts
  • TiCN – added C for toughness, low friction, very hard, coating used for punching and highly abrasive applications
  • TiAlCN – also known as Variantic. A high hardness,  low friction, good oxidation resistant versatile coating
  • TiAlN – very hard, tough with dry running abilit
  • AlCrN – a extremely hard, tough coating also used for hot forming
  • CrN – tough,smooth coating with excellent adhesion, used in metalforming tools and injection moulding part
  • CrN/CrC- low friction coating with good adhesion, used for non-ferrous tooling, dry running ability for injection moulding parts. 
Diffusion Treatments
  • Specialised Nitriding– Controlled process nitriding to match the process with your application
  • SCNSub Critical Nitriding of stainless steels done at a low temperature to not compromise corrosion resistance
  • Diffox – Specialised Nitriding + black surface oxide for improved corrosion resistance
  • Boriding – Diffusion of Boron for high surface hardness on steels and stainless steels
  • Hard Anodizing – ultimate corrosion and wear resistance for Alu.
  • Anodizing – enhanced corrosion resistance for Alu
Electroless Coatings
Surface Protection
Plated/Other Coatings
  • Flash Chrome – a thin chrome layer 5 – 15 µm with good wear resistance and good corrosion resistance.
  • Hard chrome – thicker chrome layers for wear resistance
  • MLP – added sealant for chrome plated parts – improved corrosion and friction.
  • Zinc Plating – general corrosion resistance for steels, pls enquire with us.
  • Thermal Spray – selected coatings can be applied, pls enquire with us.


We also supply precision made tooling and parts to many industries. For more information, please follow this link: Manufacturing

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.
