Compared with traditional casting techniques, investment casting is a modern precision casting method. Through investment casting, we can obtain relatively complex shapes with higher precision, so most stainless steel parts are made by investment casting.
Stainless steel investment casting process: use wax to make patterns or models, coat a layer of clay and other refractory materials, heat to melt the wax and flow out, so as to obtain an empty shell formed by refractory materials, and then pour stainless steel into the empty shell after melting, Strike with refractory to get stainless steel castings. Of course, sometimes, finished stainless steel also requires some post-processing, such as heat treatment, additional machining or some surface treatment.
