If you’re looking for the most cost-effective approach to create any prototype, vacuum casting could be the way to go. Vacuum casting, also known as urethane casting or polyurethane casting, was invented in Europe in the 1960s and has since become one of the most popular methods for creating plastic prototypes.
Vacuum casting is a versatile and cost-effective approach for producing high-quality quick prototypes and end-use components in small quantities, and it is much faster than other production methods. Pourable casting resins and silicone molds (which may be reused up to 20 times) are used to create exact duplicates of master patterns. These copies can be used for functional testing, engineering testing, product development, display models, marketing, and crowdfunding campaigns, among other things.
