Information profile @ a Glance
- Investment casting is also named lost wax casting: Process start
from a wax pattern that is invested with a refractory material to form a
mould. The wax pattern is then removed by melting leaving a negative
impression in the mould, into which the molten metal is subsequently
poured.
- The wax patterns are coated, with a refractory material. After
setting of the refractory, the wax is melted out and molten metal can be
poured in the cavity that accurately reproduces the
shape and size of the wax pattern. The cast metal item accurately
reproduces also
the fine details of the wax model.
- In the course of the production process, the goldsmith uses not only
equipment,
but also various consumable materials: the rubber for making the moulds,
the wax
for the wax patterns, the investment for filling the flask and, lastly,
the alloys.
- The casting machines developed for use in dentistry, with minor
modifications, could be used also for the industrial production of
jewellery.
- At least 50% of jewellery worldwide is
produced by investment casting
- The modern goldsmith can choose from a wide range of equipment, from
the vulcanisers, wax injectors, investment mixers and burnout furnaces,
to melting/casting machines, which represent the largest capital
investment.
- With regard to melting/casting machines, two types of equipment are
commercially available that differ in the origin of the force that
pushes the melt in the mould: centrifugal machines and static machines
