Polyurethane vacuum casting is a method for making high quality prototypes or low volumes of parts formed from inexpensive silicone molds. Copies made in this way show great surface detail and fidelity to the original pattern.

These are some of the advantages of vacuum casting.

1. Low cost for molds
2. Molds can be made in a few days
3. Many types of polyurethane resins are available for casting, including overmolding
4. Cast copies are highly accurate with excellent surface texture
5. Molds are durable for 20 or more copies
6. Perfect for engineering models, samples, rapid prototypes, bridge to production

This series is specifically catered to professionals interested in engineering, manufacturing, product design and product development.
