Manufacturing and Surface Coatings 

The TD Coating Centre (TDCC) is synonymous with the supply of high precision, high performance tooling and machine parts that improve productivity, reduce downtime and maximise part life. We do this by the correct combination of metallurgy, correct selection of base metal, appropriate heat treatment and surface engineering, and then, by high quality manufacturing of the part.  

The manufactured tooling and parts – coated or uncoated – are precision-ground (not only machined) from various steels, tool steels, specialized PM tool steels, carbides or tungsten alloys. We look at the overall design of the part including correct tolerancing to ensure a first time fit and to maximize part life. We have more than two decades of experience in this field. It’s all about getting the highest performance out of the parts. We are a one-stop solution for ultimate performance! 

The range of coatings and surface treatments we are involved in are the Thermal Diffusion (TD) coating, which has proven to outperform many competing coatings, various PVD coatings incl DLC, and surface treatments such as controlled nitriding, boriding, etc.  

We also have out own range of standard parts such as piercing punches that provide improved life and require less re-sharpening. Find our more about our exclusive range of piercing and ball lock punches, dies, pilot pins, locating pins etc. here.

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 

  • TiN, TiCN, TiAlN, TiAlCN, AlCrN and CrN including Duplex (pre-nitrided) versions 
  • YDLC (Diamond Like Carbon) – Multilayer, super low friction coating

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
  • SCN Sub 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
  • Hard Anodizing –  Hard anodizing for higher corrosion and wear resistance for Alu. 

Surface Protection Coatings and Treatments 

  • NANO Technology Surface Treatments – Coatings based on Nano-technology for hydrophobic (liquid repelling) properties, improved release for injection moulding and excellent corrosion resistance. 

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
  • Thermal Spray – HVOF, Plasma Spray and Arc Spray of metals and carbides
