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.

Investment casting has been used in various forms for the last 5,000 years. Today, more advanced waxes, refractory materials 

and specialist alloys are typically used for making patterns. Investment casting is valued for its ability to produce components 

with accuracy, repeatability, versatility and integrity in a variety of metals and high-performance alloys.

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. 

Advantages

Excellent surface finish

High dimensional accuracy

Extremely intricate parts are castable

Almost any metal can be cast

No flash or parting lines
