Investment casting offered by us is the process that uses a wax as well as thermoplastic pattern and is equipped with refractory slurry for forming a mold. It is a processing method where melted metal is casted into a form by surrounding a replaceable model with slurry that sets at room temperature. It is used for small castings and also to produce entire aircraft door frames along with steel castings of up to 300 kg and aluminum castings of up to 30 kg.
Features of Investment Casting:
Allows Undercuts in the pattern
Tolerance of 0.5 % of length are possible, and for small dimensions it can be as low as 0.15 %
Weight of the castings can range from a few grams for 60 Kgs
Minimum wall thicknesses are about 0.5 mm to 1.0 mm
Parts do not require machining because of the closed tolerances
Smooth surface finish
Excellent production rates, particularly for small components
Through dimensional accuracy and consistency
High integrity castings
Machining can be eliminates
Minimal shot blast and grinding needed
AppliSand Mouldion of Investment Casting: Typically materials that can be cast with this process are Aluminium alloys, Bronzes, Stainless Steels, Stellite etc. Glass mold accessory castings, valves and fittings, gears, Levers and Splines are some of the popular usages.Material of construction:All kind of ferreous
