Description:
Investment casting is an industrial process based on and also called lost-wax casting, one of the oldest
known metal-forming techniques.From 5,000 years ago, when beeswax formed the pattern, to today’s high-
technology waxes, refractory materials and specialist alloys, the castings allow the production of
components with accuracy, repeatability, versatility and integrity in a variety of metals and high-
performance alloys. Lost-foam casting is a modern form of investment casting that eliminates certain steps in the process.
There are a variety of materials that can be used for the investment casting process, including stainless
steel alloys, brass, aluminum, and carbon steel. The material is poured into a ceramic cavity designed to
create an exact duplicate of the desired part. Investment casting can reduce the need for secondary
machining by providing castings to shape.
Casts can be made of the wax model itself, the direct method; or of a wax copy of a model that need not be
of wax, the indirect method. The following steps are for the indirect process which can take two days to one
week to complete.
Produce a master pattern: An artist or mould-maker creates an original pattern from wax, clay, wood,
plastic, steel, or another material.
Mouldmaking: A mould, known as the master die, is made of the master pattern. The master pattern may
be made from a low-melting-point metal, steel, or wood. If a steel pattern was created then a low-melting-
point metal may be cast directly from the master pattern. Rubber moulds can also be cast directly from the
master pattern. The first step may also be skipped if the master die is machined directly into steel.
Produce the wax patterns: Although called a wax pattern, pattern materials also include plastic and frozen
mercury. Wax patterns may be produced in one of two ways. In one process the wax is poured into the
mold and swished around until an even coating, usually about 3 mm (0.12 in) thick, covers the inner surface
of the mould. This is repeated until the desired thickness is reached. Another method is filling the entire
mould with molten wax, and let it cool, until a desired thickness has set on the surface of the mould. After
this the rest of the wax is poured out again, the mould is turned upside down and the wax layer is left to
cool and harden. With this method it is more difficult to control the overall thickness of the wax layer.
If a core is required, there are two options: soluble wax or ceramic. Soluble wax cores are designed to melt
out of the investment coating with the rest of the wax pattern, whereas ceramic cores remai
