Investment Casting uses lost wax method which is not a new one. It is among the oldest known casting techniques and you will get many examples of it 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, where as in the year 1932, the ceramic block moulding process was established using the 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 strengthened development of the turbo chargers used in highflying fighters and bombers. The designers were strained to the Investment Casting to produce the required high quality mechanisms.
The era of 1950's has seen the industry expansion,mostly allied to the 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.
