The dimensional accuracy of investment castings is relatively high, generally reaching CT4-6 (CT10-13 for sand casting and CT5-7 for die casting), with a maximum of CT3. The surface roughness can reach Ra0.4-3.2 μ m, generally Ra.1.6-3.2 μ m, which can greatly reduce the cutting allowance of castings and achieve zero allowance casting.  

Investment casting can produce castings with very complex shapes that are difficult to process using other methods, such as impellers, hollow blades, etc. It can cast complex castings of various alloys, especially high-temperature alloy castings. It can cast castings with a wall thickness of 0.5mm, a minimum aperture of 1mm or less, a casting outline size ranging from a few millimeters to thousands of millimeters, a weight as light as 1g, and a maximum weight close to 1000Kg.  

Various alloy materials, such as carbon structural steel, stainless steel, alloy steel, cast iron, aluminum alloy, copper alloy, as well as casting high-temperature alloys, magnesium alloys, titanium alloys, and other precious metals, can be used for investment casting production.  

The tooling molds for investment casting can be manufactured using various materials and process methods, making them suitable for both large-scale production and small-scale production, even single piece production.
