You produce the detailed drawings that turn a part design into something a foundry can actually cast — specifying geometry, tolerances, draft angles, and the quirks of molten metal. Where design has to survive the foundry.
Most of the day tends to be in CAD, developing casting drawings, patterns, and tolerances that account for how metal flows and shrinks. You work with engineers and foundry staff, and if you ignore shrinkage or draft, a run can scrap. The craft is in anticipating what molten metal will do before it's poured.
The work differs by shop: endless variety at a jobbing foundry, a narrower repeat set at a captive one. For many, the demanding stretch can be translating clean design into messy reality — the model is perfect, the casting never quite is. Software and standards keep evolving, so skills need refreshing.
It tends to fit people who are precise, spatially minded, and patient with technical detail, comfortable thinking in three dimensions. Trade-offs can include a narrow, specialized niche and pay that tracks drafting rather than engineering. For someone who likes the meeting point of design and manufacturing, the work can be quietly satisfying.
