Vacuum molding is a common process for manufacturing small quantity items from a master pattern. This technique entails pouring a polymer blend into a mold that has been previously fabricated using a silicone compound. The vacuum removes air pockets that can appear within the compound, resulting in a stronger and more precise replica. It’s typically used for sample making and small production endeavors where other production techniques would be expensive.
Understanding Vacuum Casting Technology and its Benefits
