Since fifty years lost wax foundry has been developed to meet the precision foundry castings needs of the aeronautical industry (engines and aircraft) and the mechanical, electronic and automobile industries all over the world.

Two basic moulding processes are used by the lost wax founders and cover all fields of industrial precision foundry: the ceramic shell process and the block-mould process. Both constitute investment casting.

 

The Ceramic shell process

The ceramic shell moulds are made of successive layers of mineral binders and refractory fillers. These moulds are frequently used to cast steels, nickel and cobalt based superalloys, copper and aluminium alloys.

The ceramic shell can be used for industrial, artistic and ornamental foundry - from small or large castings, from turbine blades and other aircraft components to electronic, automotive and mechanical pieces.

Aware of this diversity, UCPI offers a wide range of refractory materials and binders to make the shells.

The block-mould process

The block mould process allows to make frame castings with very complicate internal structures which would be impossible to make using the ceramic shell system.

Mainly used for aluminium, magnesium, copper and precious metal alloys, the block-mould process allows the casting of industrial pieces from the smallest (10 to 20 mm) to the largest (60x60x60 cm).

The block-mould is obtained by mixing the HYDRACAST refractory plaster and the correct amount of water. The slip is cast in a refractory steel casing around wax patterns. The setting is quick (10 to 15 mn) and then the block-mould is dewaxed and fired. Then the liquid metal is cast.
