Investment Casting - Aluminium Alloys & Stainless Steels , Precision Tolerances Of 0.5% To 0.15% With Minimal Wall Thickness Of 0.5mm

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

Application of Investment Casting:

Typically materials that can be cast with this process are Aluminium alloys, Bronzes, Stainless Steels, Satellite etc. Glass mold accessory castings, valves and fittings, gears, Levers and Splines are some of the popular usages.
