Heat treatment of gears

Heat treatment, hard chrome plating of components

Performed externally to Westin Engineering, but managed as part of our manufacturing process.



Many of the components and gears we manufacture in our Huddersfield workshops require heat treatment prior to the finishing process, usually grinding.


The most common heat treatment process we use is quenching, whereby the component or gear is heated and then cooled rapidly in oil to produce a harder surface. Other heat treatment processes include annealing, case hardening and tempering.



Some of the components we produce require hard chrome plating to increase wear and corrosion resistance. The process involves depositing chromium onto the component from a chromic acid solution.
