FOUNDRY CASTING
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
Facilities:
- 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
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.
