Vacuum casting is a rapid prototyping process used in manufacturing industries to create vacuum products and functional plastic parts. It is conducted with a silicone master model made by SLA or CNC. In this process, a plastic sheet is heated to make it soft and pliable to stretch and vacuum on a mold. When cooled, the heated plastic takes the shape of the mold and forms a three-dimensional object. There are many examples of vacuum casting products that we see and use daily in life. These vacuum-formed products are used in food, cosmetic, and electronic industries for packaging. There are several benefits of using vacuum casting for your business.
