A very smooth surface is obtained with no parting line. However, die casting comes with higher tooling costs and typically requires at least some secondary machining to adequately finish the product. The most commonly used die casting alloys at Skellerns are gravity die cast aluminium and brass. Thus, the cost of capital has a significant role in making investment decisions. Advantages and disadvantages of stainless steel investment casting Advantages (1) As the wax mold size of stainless steel investment casting is accurate and the surface is smooth, otherwise, the mold is without parting surface, so the casting parts have a high dimensional accuracy and small surface roughness.
