Lost wax casting is used to produce detailed, intricate metal components that are then applied to a variety of industries and situations. This technique might have originated thousands of years ago, then, but it still plays a very important role in the casting of today.
Lost wax casting jewelry , also known as investment casting , is a process of metal casting in which molten metal is poured into a predetermined mold, which was previously created using a wax model that has since been melted and drained out.
To deal with this problem, the ancient Greeks adopted the process of hollow lost – wax casting to make large, freestanding bronze statues . Typically, large-scale sculpture was cast in several pieces, such as the head, torso, arms, and legs.
How to Make a Mold for Lost Wax Casting Step 1: Make a Plaster Mixture. Use two parts plaster powder to one part water. Step 2: Stir. Step 3: Imbed Wax Sculpture. Step 4: Allow Time to Set. Step 5: Pop the Mold Out of the Container. Step 6: Bake the Mold . 17 Discussions.
Advantages of Lost – Wax Moulding: The process is especially advantages for high-melting-point alloys as well as for difficult-to-machine metals. It is most suitable for producing small castings having intricate shapes. It maintains a very close tolerance of about ± 0.05 mm. It produces very smooth surfaces.
Lost – wax process, also called cire-perdue, method of metal casting in which a molten metal is poured into a mold that has been created by means of a wax model. Once the mold is made, the wax model is melted and drained away.
Derived from petroleum, this is one of the most common waxes used by lost wax casting jewelry sculptors. It is also derived from petroleum and is commonly used in candles . It’s not ideal for hand modelling jewelry, but it can be used as an additive to other waxes to make them slightly harder.
How It’s Made: Lost Wax Casting Part 2 – Casting The wax ring is attached to a rubber base to create a mold . A metal flask is secured onto the rubber base. The flask is heated overnight in an electric kiln to bake the plaster until it’s fully cured. The casting grain is weighed and placed into the crucible to melt.

The master model is used to make a wax mold out of rubber, which is heated and “vulcanized” around the master casting to make a flexible wax mold. Producing wax patterns: Molten wax is injected or sometimes poured into the rubber mold. This can be done over and over to make copies of the original design.
