The investment casting or lost wax process originates from ancient times. A number of Chinese bronze artefacts, dating from the Shang Dynasty, were created using investment casting techniques. Investment casting has been used down the ages to produce various works of art, the versatility of the process allowing intricate and delicate objects to be cast.

Advances in technology have brought investment up to date and it is probably now the most modern and versatile process used to achieve metal castings. Designers of metal components are keen to use the process as it offers reliability coupled with the ability to produce most design requirements.
