The technology of de-wax casting originated from Egypt, China and India about four thousand years ago which was followed by the entry into the industries of dental appliance and bijouterie. Then in 1930s, it was used in producing aerial turbocharger before it’s widely used in other industries. This technology has been improving in the past five decades.

Now the modern technology of de-wax casting is able to produce much bigger, more accurate, much thinner and stronger products to fit the demands in the modern times.
