Investment Casting Process

Investment casting — often called lost-wax casting — is the process behind the dense, precise stainless components that fill modern industry. From a surgical instrument body to a pump impeller to an aircraft bracket, investment casting turns a CAD model into a near-net-shape metal part with detail that would be slow, wasteful or impossible to machine. This guide walks through how the process actually works, step by step, and why engineers specify it.

Stainless Steel Casting Tolerance Guide

Tolerances decide whether a casting assembles on the first try or fights you on the line. This stainless steel casting tolerance guide explains what investment casting can actually hold, how as-cast limits compare to machined features, and how to specify tolerances on your drawing so you get a part that performs without paying for precision you do not need.

The short version: stainless steel investment castings hold ISO 8062 CT4 to CT6 as-cast, and the features that actually function — bores, faces, threads and datums — are finished on CNC centers to ±0.01 mm. Knowing which features belong in which bucket is the difference between a cost-effective casting and an over-specified, over-priced one.
