Investment Casting

Lost wax castings can be made from an original wax model (the direct method) or from wax replicas of an original pattern that need not be made from wax (the indirect method). The following steps describe the indirect process
Produce a master pattern→Create a mould→Produce wax patterns→Assemble wax patterns→Apply investment materials→Dewax→Burnout preheating→Pouring→Divesting→Finishing

Advanced wax-injection-machine and tool to ensure accurate wax-pattern.

Stable temperature and humidity environment make the wax-pattern no deformation.

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
