We, Sino sculpture Group is professional bronze sculpture foundry mainly focus on the bronze artwork, statue fabrication and related service. For a long time, bronze sculpture foundry in China is mainly based on the casting of bronze sculpture, mostly using the lost wax casting method and the lose sand casting method to realized the sculpture in bronze material.

How to use the  lost wax casting method to make sculpture?
 
Lost-wax casting also called “ investment casting" is the process by which a duplicate metal sculpture (often silver, gold, brass or bronze) is cast from an original sculpture. Intricate works can be achieved by this method.

The lost wax casting process generally has the following steps: 

Step 1, Model-making. To creat an original model from wax, clay, or other material. Wax and oil-based clay are often preferred because these materials retain their softness.

Step 2, Mould making. Normally we make a rigid outer moulds contain softer inner softer mould, which is the exact negative of the original model. Inner moulds are usually made of rubber or silicone, which is supported by the outer mould. The outer mould can be made from plaster or fiberglass and so on.


Step 3, Wax. Once the mould is finished, molten wax is poured into it and swished around until an even coating, normally 3mm thick one time and repeated until the desired thickness is reached. usually about 3 mm (​18 inch) thick, covers the inner surface of the mould. This is repeated until the desired thickness is reached.

Step 4, Removal of wax. The hollow wax copy is removed from the mould. We can also reuse the mould to make multiple copies.

Step 5, Chasing. Simple understand, “Chasing” is use a heated metal tool to make the wax mould more look like the finished piece, no parting line or flashing.

Step 6, Spruing. The wax copy normally leave a enter providing paths for the molten casting material to flow and for air to escape. The carefully planned spruing usually begins at the top with a wax "cup," which is attached by wax cylinders to various points on the wax copy. The spruing does not have to be hollow, as it will be melted out later in the process.

Step 7, Slurry. Means to make a ceramic shell-coated, it is not literally made of ceramic, but the combination of slurry and grit. This shell is allowed to dry, and the process is repeated until at least a half-inch coating covers the entire piece, except for the inside of the cup.

Step 8, Burnout. The ceramic shell-coated piece is placed cup-down in a kiln, whose heat hardens the silica coatings into a shell, and the wax melts and runs out. Now all that remains of the original artwork is the negative space formerly occupied by the wax, inside the hardened ceramic shell. The feeder, vent tubes and cup are also now hollow.

Step 9, Testing. Cool the ceramic shell and tested to see if the water will flow freely through the feeder and vent tubes.To test the thickness, holes can be drilled into the shell, then patched.

Step 10, Pouring. Pouring the melted metal into the shell, and make sure the shell is hot bacause otherwise the temperature difference would shatter it. The filled shells are then allowed to cool.

Step 11, Release. Removing the shell and releasing the rough casting.

Step 12, Metal-chasing&surface treament. Removing the casting process sign and treat the surface as request. Then the whole processes are completed.

Forging method to fabrication the large sculpture.

Above is the process of traditional lost wax method. However, as a sculpture manufacturer with 20 years of experience, sino sculpture group combines the traditional casting process and basically develops the bronze forging process at the same time, that is very good way to realized the large bronze scultpure.

The most different from the bronze casting is the material. When forging we more like to use copper plate which copper content is usually higher than 98% or more, while the general copper content of cast bronze is only about 85%. In addition, forging can ensure the uniformity of surface flatness and thickness, but for sculptures with more surface details, we still recommend the traditional casting method.
