Milestones

Investment Casting uses the lost wax method, which is not a new one. It is among the oldest known casting techniques and you will find many examples of it used to produce jewelry and statuary. In the initial part of this era, the Investment Casting Technique was used to manufacture gold fillings as well as dental inlays to make artificial teeth, while in 1932, the ceramic block molding process was established using cobalt-chromium alloys to produce orthopedic components and dental applications.

The Second World War has completely changed the scenario of casting techniques and they were used for the introduction of aircraft gas turbines and to strengthen the development of the turbo chargers used in high-flying fighters and bombers. The designers were strained by the investment casting to produce the required high-quality mechanisms.

The era of the 1950’s has seen industry expansion, mostly allied to military and aircraft applications; however, with the knowingly increasing involvements in the overall commercial field during the mid-50’s, the material investment casting range has dramatically increased to copper alloys, original alloys, magnesium alloys, as well as titanium alloys to characterize the process versatility.
