It was good to see a coil spring machine originally used in the Swindon Railway Works still in use providing springs for today's railway.
The spring properties are produced by careful heat treatment of the component as it is passed through a long oven where a series of burners produce the appropriate temperature profile.
Production of some parts requires the use of a Shot Peening Booth. Shot peening is a cold working process used to produce a compressive residual stress layer which alters the mechanical properties of the metal by impacting the surface with lead shot, creating plastic deformation.
Various Spray Booths are provided for painting finished products.
Many thanks to Andrew for his courtesy in showing me around the Spring Shop.
