Metal Casting (Moulding)

Metal Casting is most often used for making complex shapes that would otherwise be difficult or uneconomical to make by other methods. The Bloore & Piller foundry melts a wide range of materials which are cast into both simple and complex items on a routine production basis. We have a depth of expertise in metal casting which is complimented by CAD design and pattern making.

Examples of castings are:

Cambrian lines – valves and heavy duty hose fittings.

Industrial – transformer and switchgear fittings, sliding door hardware, tool components. Highly specialised componentry for industries such as medical. electronics and railway infrastructure.

Agricultural – blades, sprockets, pump casings, wear and corrosion resistant parts for rock crushers, fertiliser manufacturing plants, agricultural machinery.

Commercial and Domestic – plaques, gas burners, foot pedals, special set spanners, cookware.

Materials cast in the Foundry include:

  • Aluminium
  • Brass
  • Copper
  • Gunmetal
  • Bronzes
  • Grey and SG iron
  • Ni-resist, Ni-hard and SG Ni-resist
  • Magnesium
  • Mild, stainless, heat and wear resisting steels.

Techniques Used:

  • Resin Sand/Hard Sand
  • Green sand
  • Cold set sand (CO2)
  • Shell cores


  • 175kW Electric induction furnace with three separate stations
  • Electric Resistance Furnace and Diesel Furnace
  • Moulding machines
  • Shell core machines
  • Pattern shop – wood, metal or plastic patterns
  • Shot, grit and tumble equipment for cleaning and finishing

Facilities are equipped for short or long run production. As a production facility the maximum casting capacity is 1400 x 750 mm and 250.0 kg. Larger sizes can be cast but only as specials.

Heat Treatment

Ferrous and non-ferrous materials are heat treated when required, utilising a gas-fired salt bath facility.

Types of heat treatment covered are:

  • Annealing
  • Normalising
  • Hardening
  • Tempering

Maximum size 400 dia. x 450 mm

Examples of heat treated items are:

Sharpening steels, automotive U bolts, steel sprockets, pump casings and tooling. Process annealing a variety of items prior to upsetting or pressing.
