TECHNOLOGICAL PROCESS
Investment casting is a manufacturing process in which a wax pattern is coated with a refractory ceramic material.
It has precise dimensions and low surface roughness. It greatly reduces the machining amount of castings or can be used directly without machining.
The process begins with a precision-engineered wax injection mold to produce wax patterns representing the final part.
Wax Pattern
The wax injection mold is quantified to run production and brought to the Wax Room for injection and assembly.
Ceramic Mold Construction
The wax tree is dipped and completely enveloped into ceramic slurry, taken out, then completely coated in sand to create the first layer of shell, and then dried.
De-waxing
The shell, which consists of the wax pattern and its coating of ceramic and sand, is placed into an autoclave to quickly remove the wax under extremely high pressure and steam heat.
Foundry & Pouring
The mold is then placed into a high temperature oven, approximately 1000°C (1832°F), to cure (cristobalite) the ceramic mold and prepare it for accepting molten metal.
Shell & Casting Removal
After the metal has cooled to the touch, the ceramic mold shell can be broken away from the part(s), and the casting(s) removed from, the now metal, tree.
Finishing
Often, the part’s gate is removed by a grinding or machining post-cast operation.
