At the Cambrian foundy a wide range of materials are cast into both simple and complex items on a routine production basis. Cambrian Engineering has a depth of expertise in metal casting which is complemented by CAD design and pattern making. Casting is most often used for making complex shapes that would otherwise be difficult or uneconomical to make by other methods.

Materials cast in the Cambrian Foundry are:

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.

Substantial stocks are held of most materials.

Techniques used are:

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

Facilities include:

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 50.0 kg. Larger sizes can be cast but only as specials.

Examples of castings are:

Cambrian lines – valves and heavy duty hose fittings,

Industrial – transformer and switchgear fittings, sliding door hardware, tool components.

Agricultural – sprockets, pump casings, wear and corrosion resistant parts for rock crushers and fertiliser manufacturing plant.

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

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:

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