Customer concept can be a sketch, blueprint or electronic data. This is used to produce the Wax Mold and any necessary fixtures.
The patterns are made by injecting molten wax into the aluminum tool using a sophisticated wax machine. The machine controls the temperature, flow rate, pressure and dwell time of the wax preset parameter devices.
The wax patterns are cleaned and inspected for visual defects, in some cases using a borescope to assure cavities are wax free.
The Patterns are “clustered together” on a base to form a “tree” or “mold”. The tree contains the desired parts, gates to the part and runners and pouring cup.
The tree is dipped in slurry, drained and then coated with sand.
Parts are hung on the conveyor.
