Investment casting is an industrial process based on lost-wax casting, one of the oldest known metal-forming techniques. The term 

"lost-wax casting" can also refer to modern investment casting processes.

Water glass and silica sol investment casting are the two primary investment casting methods nowadays. The main differences are the

surface roughness and cost of casting. Water glass method dewaxes into the high-temperature water, and the ceramic mold is made of 

water glass quartz sand. Silica sol method dewaxes into the flash fire, and silica sol zircon sand makes the ceramic mold. Silica sol method

costs more but has the better surface than the water glass method.

The process can be used for both small castings of a few ounces and large castings weighing several hundred pounds. It can be more 

expensive than die casting or sand casting, but per-unit costs decrease with large volumes. Investment casting can produce complicated 

shapes that would be difficult or impossible with other casting methods. It can also produce products with exceptional surface qualities and 

low tolerances with minimal surface finishing or machining required.

Advantages

·         Excellent surface finish

·         High dimensional accuracy

·         Extremely intricate parts are castable

·         Almost any metal can be cast

·         No flash or parting lines
