Shell molding, also known as shell mold casting or the Corroning process, is a form of metal casting dating back to the middle of the 20th century.The metals of shell mold casting are most commonly using cast iron, carbon steel, alloy steel, stainless steel, aluminum alloys, and copper alloys. A sizable amount of the casting in the steel industry are made by shell molding process, that ensures better profitability. Typical parts manufactured in industry using the shell mold casting process include cylinder heads, gears, bushings, connecting rods, camshafts and valve bodies. Read More

Valves are usually made of metal or plastic and they have several different parts. The outer part is called the seat and it often has a solid metal outer casing and a soft inner rubber or plastic seal so the valve makes a closure that's absolutely tight. The inner part of the valve, which opens and closes, is called the body and fits into the seat when the valve is closed. There's also some form of mechanism for opening and closing the valve—either a manual lever or wheel (as in a faucet or a stop cock) or an automated mechanism (as in a car engine or steam engine).
