||The contemporary engineer
thinks in terms of investment casting.
||First, we create a suitable mold for
producing a wax pattern to close tolerances. Under pressure,
we inject molten wax into the mold cavity.
||We then mount these wax patterns with
appropriate gates and runners and dip the wax pattern
into slurry of investment ceramic investment material
and allow it to harden. We repeat this until a tough shell
||We then remove the wax form the pattern
material by heating the ceramic mold in a high-temperature
furnace. The material is lost. Next pour molten metal
into the ceramic mold.
||After solidification, the metal parts
are removed from the investment material. Each lot is
inspected for quality to insure complete satisfaction.
The final product is an intricate lost wax investment
casting with close dimensional accuracy, sound structure,
and fine surface finish.
