How to Slip Cast Urethane Resin, to Simulate Blow-Molded Parts

Here industrial designer Eric Strebel shows us how to do something tricky: Using casting to create a part that would, in production, be blow-molded. “This week’s video is about adapting a ceramics technique called ‘Slip Casting’ to the world of resin casting,” Strebel explains. “I show you how I use the method to simulate a blow molded medical part to make a functional prototype.

This slip-casting process takes patience and proper technique, so be thankful that Strebel’s already figured out how to do this right and walks you through it:
