How to deal with shrinkage issues in polyurethane resin parts during vacuum casting
J
Hi, I am concerned about shrinkage in polyurethane vacuum-cast parts during the curing process. These parts have tight tolerances, such as ±0.2 mm, and some features are designed carefully to fit together, such as snap joints or press-fit inserts. Should I make adjustments to my CAD model sizes to account for shrinkage, or is this something that the mold manufacturer automatically takes care of?
