Image Source: pexels Vacuum casting is a versatile method for producing prototypes and low-volume production parts using polyurethane (PU) or epoxy resins. One of the most critical factors for part quality is wall thickness. Proper wall thickness ensures consistent resin flow, minimal shrinkage, and dimensional stability, while poor design can lead to warping, sink marks, or incomplete casting. This guide provides minimum and recommended wall thickness ranges, practical design tips, and engineering considerations for vacuum-cast parts. 1. Minimum and Recommended Wall Thickness The optimal wall thickness depends on part size, geometry, and resin type. Below are general guidelines: FeatureMinimum ThicknessRecommended…
