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 Coatings

  • CrN – tough, smooth coating with excellent adhesion, used in metal forming tools and injection moulding parts
  • ​TiN – durable, high hardness, used on metal forming dies and injection moulding parts
  • TiAlN – very hard, tough with dry running ability
  • TiAlCN – aka “Variantic”, a low friction, high hardness, good oxidation resistant, versatile coating
  • AlCrN – a extremely hard, tough coating, also used for hot forming
  • TiCN – added C for toughness, low friction, very hard, coating used for punching and highly abrasive applications
  • CrN/CrC– low friction coating with good adhesion, used for non-ferrous tooling, dry running ability for injection moulding parts.
  • DLC– Diamond Like Carbon with a very low friction coeff. Only available as a coating on internationally manufactured parts
Diffusion Treatments
  • Nitriding– Specialized nitriding to match the process with your application. Mould steel nitriding for a smooth, hard surface that can easily be repolished.
  • Diffox – Specialised Nitriding + black surface oxide for improved corrosion resistance
  • SCN – Sub Critical Nitriding of stainless steels done at a low temperature as not to compromise corrosion resistance
  • Boriding – Diffusion of Boron for very high surface hardness on mild steels, alloy steels and stainless steels
  • Anodizing –  Conventional anodizing for enhanced corrosion resistance and a great appearance, and hard anodizing for ultimate corrosion and wear resistance for Alu. 
Electroless Coatings
  • Electroless Nickel – high phosphorous, excellent corrosion resistance, low friction and can be age 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 5 – 15 µm with good wear resistance and good corrosion resistance.
  • Hard chrome – thicker chrome layers 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.
