Diagram illustrating the steps of investment casting: wax pattern, dipping in ceramic slurry, shell drying, wax removal, metal pouring, and final casting. Hand-drawn sketch style.

Wax Pattern A basic drawing of the wax model, possibly with runners or a “tree” if multiple parts are made at once. Dipping into Ceramic Slurry A sketch showing the wax model being dipped into a liquid ceramic coating, with a label like “ceramic slurry.” Ceramic Shell Drying The wax model fully coated in a hardened ceramic shell—this can be a cross-section to show the wax inside the shell. Wax Removal A diagram showing the wax being melted out (usually an arrow and “heat” label), leaving a hollow shell. Metal Pouring An illustration of molten metal being poured into the ceramic mould—can be as simple as a crucible and arrows. Final Metal Casting A rough sketch of the finished part, with the ceramic shell broken off. See more
