Process of Investment Casting

Wax Injection

Wax patterns are made from internationally used filled waxes, achieving better accuracy and finish

Way Assembly

Patterns are assembled to ensure appropriate yield and ease of production using scientific methods. when required, simulation software’s are used to ensure perfect methoding and appropriate orientations
to ensure robust castings eliminating almost all defects

Shelling

Slurries are periodically checked for its viscosity and ph test zirconium products are used for primary coats and aluminum silicate with fused silica are used for secondary coats
We built ceramic shells exclusively by hand to specialize in getting complex details which is not always possible with foundries utilizing robotics

De-waxing

De-waxing of the shell is done using an autoclave with steam boiler

Melting process

Shells are baked and liquid metal of any grade can be cast using Induction Melting Furnace

Fettling and finishing

Fettling is carried out for the purpose of removing the shelling material, gates, runners, risers and chipping of any of unwanted projection of castings. Several finishes are attained as per customers requirement.
