Using investment castings produces components that are best described as near-net-shape, in other words, components that require little or no further processing. The process is capable of producing precise detail and dimensional accuracy of approximately +/-0.005” per inch of dimension in castings of up to 200 pounds or just a few ounces.

Hundreds of different alloys can be cast using the investment casting process, in most commonly used base metals such as steels, stainless steel s, copper, nickel, irons, cobalt, and more. A key advantage often overlooked is that since finish machining can be minimized or eliminated, alloy selection can be upgraded to stronger metals, which are typically harder to machine, resulting in better performance of the end product. Henan Metals casts most of the common engineering metals used by a wide range of industries, as well as many specialized metals for demanding applications.

Henan Metals & Minerals could use three ways to produce the investment castings / lost wax castings:

1.The sodium silicate process for large- scale parts

2. The silicon sol process for high dimension precision and high finish parts

3.Compound technology are somewhere in between

Referred to the weight of investment castings, Henan Metals & Minerals can supply from 10 g to 130 kg.
