Investment Casting (or) Lost Wax Method

A wax duplicate of the desired casting is created to be invested into a \"Ceramic Slurry\".

The slurry covered investment can be dipped into alternating coatings of sand and slurry until a suitable thickness of shell is achieved that can hold the molten metal after the investment is burnt out.

The \"Burn-Out\" process requires that the investment and coating are inverted in an oven that is fired to 1800F so that the investment can flow out and be recovered. The refractory coating is also cured in this procedure.

This process is beneficial for casting metals with high melting temperatures that cannot be moulded in plaster or metal.

Parts that are typically made by investment casting include those with complex geometry such as turbine blades or fire arm components. High temperature applications are also common, which includes parts for the automotive, aircraft, and military industries.

Principle

Method also called as precision investment casting. The method involves the use of expendable Pattern with a shell of refractory material surrounded to form a casting mould. Since the pattern made up of wax is melted out and gets destroyed. That is why the name-\"Lost wax method\".

Refractory slurry is formed around a wax or plastic pattern and allowed to harden. The pattern is then melted cut under mould is baked. The molten metal into the mould and solidifies.

Pumps

Valves

Pipe Fittings

Automotive

Marine and Oil

Machinery

Power & Energy
