The mold-making operation itself: pattern allowances by alloy, sand and binder targets, ramming and mold hardness, gating and riser design, vents, closing, pouring temperatures and shakeout – plus when a printed sand mold removes the pattern entirely.

How lost wax casting works, step by step: pattern waxes, ceramic shells, dewaxing, burnout, pouring, tolerances and the defects to watch for.

Industrial SLS pricing bands, coated sand and PSB wax consumables, laser time and a per-part worked example, with a worksheet for filling in your own local costs.

Casting defects diagnosed by location rather than guesswork: gas vs shrinkage porosity, blowholes, hot tears and sand defects, with causes, fixes and a 22-row reference table.

The sand casting process from pattern to finished part: six steps, five molding methods compared, sand and binder selection, gating and riser design, and pattern options.

A foundry audit that fits in one visit: the documents to request, what to watch on the floor, a 25-point scorecard, and the findings that should end the visit.

Alloy, size and tolerance set your shortlist. Annual volume picks the winner. A three-way comparison of sand, investment and die casting, with the crossover points that decide it.

Where 3D printing fits into investment casting: printed wax patterns, rapid tooling from printed masters, tooling-free prototyping, and an honest look at what it does not change.
