Stainless steel has its own classification and grading. Stainless steel contains iron, carbon, chromium, and other materials. Chromium is the primary element that makes stainless steel corrosion resistant and is contained in no more than 10.5% of each unit. Depending on the availability and percentage of other materials, stainless steel can be classified into different grades. For casting purposes, we would say that grades  304 and 316 stainless steels are the best . They are both above the 300 level and both contain nickel. Therefore, make sure the stainless steel foundry you hire has 304 and 316 stainless steel available.   Stainless Steel Investment Casting Procedures 1. Prepare the pattern with wax At the beginning, you will need to prepare a replica of the final product in wax. You can use other materials, such as foam or plastic. But wax seems to be the best choice because it melts easily, which will pay off in the later casting stages. 2. Make a tree with wax patterns I...

Stainless steel - we see it everywhere now, from our glasses to our smartphones to complex machinery. Stainless steel is everywhere. The reason is its corrosion resistance. The investment casting process, also known as precision casting or lost-wax casting, involves the forming of a ceramic mold from a wax pattern. Wax patterns are made in the exact shape of the item to be cast. Refractory ceramic is used to coat this pattern. Once the hardened ceramic material has been turned upside down, the wax melts and drains out. Hardened ceramic shells become disposable investment molds. The molten metal is poured into the mold and allowed to cool. The metal casting is then removed from the spent mold. The process of "investing" (enclosing) a pattern with refractory materials is called investment casting. The advantages of investment casting over other molding methods include fine details and excellent surface finishes as-cast. Castings with thin walls and complex internal passageways ...

 Die casting is a metal manufacturing process that involves pressing molten metal under high pressure into a reusable metal mold. Die casting creates metal parts that are dimensionally accurate, well-defined, and have a smooth or textured surface. Commonly used in the manufacturing industry, die casting is a casting process that involves forcing molten metal through the cavity of a pre-shaped mold. Base metals such as zinc, aluminum, copper, magnesium and lead are first heated until they achieve a molten state. The newly molten metal is then forced into a pre-shaped mold using pressure. Once the molten metal has cooled and hardened, it's removed from the mold. The two main die casting processes. Hot Chamber Die Casting Molten metal is forced through the cavity of a pre-shaped mold using pressure. The defining characteristic of hot-chamber die casting is that metal is heated inside the casting machine rather than a separate machine or furnace. Hot-chamber die casting is a relatively...
