Jet propulsion for military and civilian aircrafts gaveinvestment casting the foremost status in the casting industry. From heavy casting of 300Kg to small casting of 30 kg, this casting method is used for as wide for hi-tech industrial applications. This process is more expensive than sand casting in terms of the casting techniques, but the equipment are relatively cheaper. But still, investment casting is largely relied on for complicated designs that cannot be casted using any other method. Investment casting finds widespread application in spacecraft, jet engines, etc. Though this industry is heavily depended on the aircraft industry, it is is find our new field of application to broaden its horizon.
