Create Custom Resin Blanks with WoodRiver Silicone Casting Molds

Casting your own blanks opens the door to a more personal, creative project. With WoodRiver Silicone Casting Molds, turning pens, rings and stoppers becomes a custom process from the very start. These molds provide dependable shape, clean edges and consistent results. Designed for use with epoxy or polyester resin, they offer flexibility for makers who want to push beyond off-the-shelf blanks.

Each mold features a 3 mm internal fillet at the corners to make blank removal easier and to create smoother transitions. The top four edges remain square to provide stability and keep the shape precise. This thoughtful design simplifies the process and helps reduce cleanup or post-cast shaping.

Pen turners can pair the pen blank mold with In-Tube Pen Dams to cast directly around pen tubes. This approach keeps the resin clear and the pattern clean. The result is a finished blank that shows off embedded materials, pigments or swirls without distortion. For ring makers or bottle stopper blanks, the handle stock mold offers a larger cavity with similar flexibility.

Flat Dams allow you to create quick, single-pour blanks for bottle stoppers or custom projects. These dams work seamlessly with the molds and give you more control over size and volume. They’re ideal for one-offs, testing new resin blends or experimenting with color combinations.

To keep molds in top condition, apply mold release spray before pouring and clean with denatured alcohol after use. These simple steps protect the silicone and ensure long-term performance.
