Process

Investment Cast (WAX Loss)

01 Wax Making

Wax replicas of the desired castings and produced by injection moulding using a metal die. These replicas are called "patterns".

Alternate Text
02 Wax Assembly

This patterns are attached via a "gate" to a central wax stick, referred to as a "tree" or "sprue", to form a casting cluster or assembly, and mounted on a pouring cup.

Alternate Text
03 Investing

A shell is built by immersing the assembly in a liquid ceramic slurry and then into a bed of extremely fine sand. Several layers may be applied in this manner.

Alternate Text
04 Dewaxing

Once the ceramic is dry, the wax is melted out in an autoclave, creating a negative impression of the assembly within the shell. The shell mould is then fired in a high temperature oven.

Alternate Text
05 Casting

The shell is filled with molten metal using various techniques and, as the metal cools, the parts, gates, tree and pouring cup become a solid casting.

Alternate Text
06 Knock Out

When the metal has cooled and solidified, the ceramics shell is broken off by vibration or water blasting.

Alternate Text
07 Cut Off

The parts are cut away from the central tree using a high speed friction saw.

Alternate Text
08 Finishing

Minor finishing operations, such as fettling and grinding, are undertaken to produce a metal casting identical to the original wax pattern.
