The TD Coating Centre is synonymous with 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 physical metallurgy, correct selection of base metal, appropriate heat treatment and surface engineering and then, by correct manufacturing of the part. In selected cases we will only apply an appropriate surface coating or surface treatment.

Our exclusive range of coatings and surface treatments include the Thermal Diffusion (TD) coating, which has proven to outperform many competing coatings, various PVD coatings and other thin film surface coatings to provide parts that outperform and outlast. Surface treatments include highly controlled nitriding, boriding, etc.  

The manufactured tooling and parts – coated or uncoated – are precision-ground (not only machined) from various steels, tool steels, PM tool steels or carbides. 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! 

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.  

Please contact us to see how we can assist you. 

We have introduced a new series of non-conductive, tough and wear resistant Ceramic weld pins specifically for projection welding. The pins are highly resistant to weld spatter – request the catalogue here http://www.td.co.za/articles-and-info/.

Click below to find out more about our offering:

  • Custom made tooling and parts – made to your specification from Steels, Alloys steels, Tool steels, Powder Metallurgy steels, Carbide, Tungsten (pure), Aluminium Oxide, Silicon Nitride, etc. 
  • FANG range – standard piercing punches, dies and other die support products
  • Carbide tooling and parts – tungsten carbide/cobalt parts made to your specification
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 – Thin, hard wear resistant coatings for high precision parts

  • ​TiN, TiCN, TiAlN, TiAlCN, AlCrN and CrN including Duplex (pre-nitrided) versions 
  • DLC (Diamond Like Carbon) – Super low friction coating incl. 
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 
  • Zinc-Aluminium Flake Coatings – the new industry standard for thin zinc layers giving excellent corrosion resistance (> 1000 hrs NSS)
  • Protective Coatings – Gunkote, fastener coatings for marine and severe corrosive exposure, food-grade Teflon coatings, dry film lubricants (MoS2, Graphite, etc) 
  • NANO Technology Surface Treatments – Coatings based on Nano-technology for hydrophobic (liquid repelling) properties, improved release for injection moulding and excellent corrosion resistance. 
  • Polymer Sealant – sealant for chrome plated parts for improved corrosion protection and lower friction (aka “MLP”)
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
