Lost wax casting

The waxing process, also known as peach, is a metal casting process in which molten metal is poured into a wax-made mold. After the mold has been made, the wax mold melts and discharges. The hollow core can be realized by inserting a heat-resistant core that can prevent the molten metal from completely filling the mold. GM can be found on all continents outside of Australia and has changed from the third millennium to the date of lost wax before Christ and has continued since then.

Lost wax casting

Metal cast models of apples and plaster molds using the lost wax method.

To pour a clay model onto a bronze bowl, use the model to make a mold, then clean the inside of the bottom mold with a molten wax brush to the desired final thickness of the bronze. After removing the mold, the resulting wax shell is filled with a heat-resistant mixture. The wax tube is attached to the outside of the wax bowl. The wax tube provides a channel for copper casting during the casting process and ventilation for the poisonous gas generated in the process. The wax tube can be modeled or adapted by the artist. The metal pin is driven into the core through the housing to secure it. Then completely cover the prepared wax bowl with a heat-resistant plaster layer and place the entire oven upside down in the oven. During the heating process, the plaster dries and the wax flows out through the channel formed by the wax tube. Then the plaster mold is filled with sand and then molten bronze is poured into the pipe to fill the space left by the wax. After cooling, the outer plaster and the core are removed and the bronze can be finished. See also investment casting; Sculpture: replication and surface treatment technology.
