Image Source: unsplash Vacuum casting is a highly cost-effective prototyping process—but how precise can it really be? In this guide, we dive into the typical tolerances achievable with urethane/a cast parts, the key factors that influence dimensional accuracy, and the quality control strategies you should use to minimize variation. Whether you’re designing for tight-fitting assemblies or functional prototypes, this page gives you a clear engineering-level understanding of what to expect, and how to design for optimal accuracy in vacuum cast components. You can expect vacuum casting tolerance to be about ±0.3 mm or ±0.3% for most parts. This accuracy depends…
