HISTORY OF PRECISION CASTINGS
Precision casting is commercially know as 'Investment casting or lost wax casting'.
Precision casting is the most ancient of metal casting arts, at the same time also the most modern and versatile. This process has been known and used for centuries. The history of 'lost wax' process goes back in time beyond the Egyptian pyramids. Artisans of Shang dynasty in China (766 - 1122) created art works of bronze into delicate filigree. Historians have lost track of the Precision Casting in Europe and Asia until the 16th century. but half way round the world in Cauca valley in Columbus. The remarkable statue "Shiva, lord of Dance" was produced during the 8th and 9th century in India.
During the 16th century, the process was widely applied by artist and sculptors. Benvenuto Cellini produced many sculptors by this process. The most outstanding is the bronze statue of the perseus and the head of Medusa.
The "lost wax process" was also adapted by dentist during the late 19th century to produce accurate castings for filling croens, bridges etc, often in gold. The continued development of the process during the early years of the 20th century laid the foundation of the engineering process as it is known today.
