Vacuum casting is a common method for producing small volume parts from a prototype pattern. This approach requires injecting a polymer composition into a mold that has been previously created using a silicone substance. The negative pressure removes air pockets that can appear within the compound, resulting in a higher quality and more precise duplicate. It’s typically utilized for prototyping and limited run projects where other production techniques would be costly.
