We have rich experience in metal Investment castin g, such as copper investment casting, aluminum investment casting.
Investment casting, here often called lost wax casting, is regarded as a precision casting process to manufacture near-net-shaped metal parts from various kinds of alloy. It is often be used for the production of components requiring precision, complex, often with thin-wall castings.
We can use investment casting to offer many ferric and non-ferric castings, such as copper alloy casting, aluminium casting and Steel investment casting, stainless steel casting, high resistant steel casting , carbon steel castings, Cutting Tool steel castings, low alloy steel castings, high speed steel alloy, heat resistant steel casting, corrosion resistant steel casting, wear resistant steel, abrasive resistant steel castings and other specialty steel casting, . And also available for the service for post-treatment, such as blasting, heat treatment, polishing, machining, zincing, plating, anodizing, plus good service, we hope we can earn your trust in this field.
The casting tolerance our foundry can reach a precision from CT3 to CT9 according to stand ISO 8062 by choosing different investment casting craft and materials.
Investment casting are always classified in 3 types, one we called here is American style silicon gel process(with green wax and better sand) with very smooth surface, tight tolerance, suitable for small part making widely used for stainless steel, carbon steel. It's different with Russian style investment casting actually called soluble glass process(with white wax and rough sand)with relative rough surface, bigger tolerance, suitable for large part making more than 1.00KGS especially for carbon steel, alloy steel, sometimes also for ductile iron and grey iron. And the complex shell process just fall between the 2 types silicon gel process and soluble glass process。
