Part I of this video tutorial demonstrates how to make a brush-on mold using tin-cured silicone rubber (TinSil® 80-30).

In Part II, we complete the project with the following:

• mold shell construction (using Poly 1512X polyurethane plastic)
• cutting the mold
• how to make a plastic casting using a rotational casting machine (using EasyFlo 120 polyurethane plastic)

The Steps in Part I of this tutorial:

1. Establish Pour Hole
2. Weigh & Mix Rubber for First Layer of Mold
3. Brush-On First Layer of Mold
4. Weigh, Mix & Brush-On Second Layer of Mold
5. In the Meantime, Cast Rubber Pieces for Parting Line & Keys
6. Weigh, Mix & Brush-On Third Layer of Rubber
7. Weigh, Mix & Brush-on Final Layer of Rubber
8. Create Thick Parting Line

The Steps in Part II of this tutorial:

9. Construct Mold Shell
10. Remove Mold Shell
11. Cut Parting Line in Mold

The Final Step: Rotational Casting with EasyFlo 120 Polyurethane Plastic
