Softer silicone for mold - any impact on accuracy?
P
Hi, looking for help with the following. Some of my functional prototypes for vacuum casting have a few tricky undercuts. I’m thinking of using softer silicone for the mold to make demolding easier, but I’m worried it might mess with the dimensional accuracy of the parts. How much does softer silicone really impact accuracy, especially when tight tolerances are involved?
