Material: Alloy Steel, Stainless Steel, Carbon Steel Process: Investment Casting + Machining Weight: 2.20 kg
Precision Investment Casting Foundry with Machining Services, from Idea to the Markets.
Almost most of the ferrous and nonferrous metal and alloys could be cast by investment casting process. But, at our lost wax casting foundry, we mainly cast the carbon steel, alloy steel, stainless steel, super duplex stainless steel, gray cast iron, ductile cast iron, aluminium alloys and brass. Additionally, certain applications require the use of specialized other alloys used primarily in harsh environments. These alloys, such as Titanium and Vanadium, meet the additional demands that might not be achieved with standard Aluminum alloys. For example, Titanium alloys often are used to produce turbine blades and vanes for aerospace engines. Cobalt-base and Nickel-base alloys (with a variety of secondary elements added to achieve specific strength-strength, corrosion-strength and temperature-resistant properties), are additional types of cast metals.

Because the ceramic shell is assembled around smooth patterns produced by injecting wax into a polished aluminum die, the final casting finish is excellent. A 125 rms micro finish is standard and even finer finishes (63 or 32 rms) are possible with post-cast secondary finishing operations. Individual metal casting facilities have their own standards for surface blemishes, and facility staffs and design engineers/customers will discuss these capabilities before the tooling order is released. Certain standards depend on a component’s end-use and final cosmetic features.
