What sets the price of an investment casting: alloy, weight, yield, complexity, shell route, tooling, finishing and testing, and how to reduce cost.
Practical design rules for investment castings: wall thickness, uniform sections, radii, holes, draft, gating and machining allowance.
What tolerances investment casting can hold, how ISO 8062 CT grades work, what affects accuracy and how to specify tolerances on a casting drawing.
The two main investment casting shell processes compared: surface finish, tolerances, alloys, part size and cost, and when to use each.
How investment casting, die casting and sand casting compare on alloys, detail, tolerances, surface, tooling cost and volume, and how to pick the right process.
