Below is a list of Wax Casting manufacturers from Carson City, Nevada. Wax casting is a process that uses a wax pattern to create metal parts. This technique is also called the lost wax or investment casting process. Aluminum, copper and stainless steel are among the most commonly used metals; almost any castable metal may be used including gold, titanium and brass. Due to the smooth surface of the wax pattern that is used to create a ceramic mold, the resulting parts have a very fine finish that requires little machining.
