Heat Treatment Processes
a) Conventional Processes

Steels:-

  • Neutral hardening and tempering

  • Atmosphere normalising

  • Carbon Restoration

  • Gas carburising

  • Carbonitriding

  • Annealing and stress relieving

Non-Ferrous alloys:-

  • Annealing and stress relieving of Copper and Aluminium alloys

  • Age Hardening of Aluminium alloys

Licenced Processes - Exclusive for South Africa. Technology owned by BOC Ltd.(U.K.)

Low temperature nitrocarburising processes to combat wear and corrosion. These processes were developed by Huyton Heat Treatments in the U.K. In 1996, P.H. Heat Treatment was, after extensive auditing by Huyton, awarded an exclusive licence for South africa for these processes. These processes have had success in the automotive and mining industries.

They include well known process names such as:

  • Alpha - ( Epsilon / FNC / SQ / AS / L )

  • Alpha Plus - ( Epsilon ANC / SQ / MS / L )

  • Beta - ( Epsilon EANC / SQ / MS / H )

  • Delta

  • Sealbond - ( Epsilon FNC / S or SU )

BOC purchased the technology from Huyton this year and have renamed the processes "Epsilon".

Customer Information System
Developed in-house for tracking, pricing and statistics on all customers and their orders. The system was developed in Microsoft Access with VBA coding. It is networked throughout the factory and provides up to date information on all
customers' orders. This system was introduced in 1999 and has facilitated major improvements in efficiency, resulting in improved customer service and satisfaction.
