Urethane Casting Guidelines

So, how does urethane casting actually work? Of course, you can make about anything you want, but the process doesn’t vary too much. Let’s get started.

Urethane Casting

The Basic Process

Casting generally begins with a stereolithography (SLA) master pattern of the prototype. The pattern is inspected for accuracy, refined and prepared for a silicon rubber mold (SRM).

To create the SRM, a process called room temperature vulcanization or RTV is used. The part, again, is inspected to determine the best setup. Parting lines are set and gates and vents are considered to ensure the best mold fill and minimize bubbles.

Finally, silicon is poured around the SLA master to create the mold. After the silicon has had time to cure, the pattern is removed. The mold is put back together, and urethane material is poured into the mold and the part is created.
