Process Flow
Tool making
First stage of the Process is to design and develop tool for the wax injection for particular part with use of CNC machine.
Wax Injection
This process is to produce a replica of the required casting. This is made by injecting wax into a tool.
Pattern Assembly
These patterns are attached via a ‘gate’ to a central wax stick, referred to as a ‘tree’, to form a casting cluster or assembly, and mounted on a pouring cup.
Shell Coating
The wax tree is dipped in ceramic slurry, which is then coated with sand in a dedicated coating cabinet.
Dewaxing
The coated wax trees are dried in humidity controlled air cabinet.
Pouring
Dewaxed Shell are preheated at specific temperature and filled with molten metal, as the metal cools, the parts, gates, tree and pouring cup become a solid casting.
Shell removing
Once the metal has cooled sufficiently the ceramic shell is vibrated off the cast product by the use of a pneumatic knockout machine.
Heat treatment
The parts are cut away from the central tree and heat treated at specific temperature to get uniform structure and desired properties.
Finishing
Products are finished with shot blasting, grinding and machining for smooth finish.
Final Inspection
The final inspection and required tests are performed on each product to check dimensions and mechanical properties.
