Tutorials for Molding and Casting


Taking a prop that you’ve made and making a copy can be scary–but don’t worry, it can be pretty simple! Start with a small prop and make a one-part mold. Follow along in our tutorial videos in the playlist below to learn the full process of silicone molding and casting plastic resin copies.

For our molds, we tend to use Smooth-On products, since they are reliable and have a great variety of materials. Another company with mold products is TAP Plastics, who also has the great benefit of carrying plastic sheets for other cosplay needs. For finding silicone and resin suppliers in your area, go to your local pottery supply store. They sometimes carry molding supplies, or can at least point you in the right direction.

We recommend starting small with trial size kits of silicone and resin. The materials below link to the smaller kits sold on Amazon. These links help support Punished Props–thank you for using them! If you’re looking for larger size material containers, go straight to the company’s website.

Builds with Molding and Casting


Our prop and costume builds listed below include our molding and casting techniques. Most of our molds are one-part or two-part molds. Our most complicated build to date is the District 9 Rifle, which involved our first matrix mold. We later improved the matrix molding process for the Bleach Hollow Mask.

Prop: Shop – Mister Handy Scale Model Build

Bill made his own Fallout 4 Mister Handy scale model! The replica prop figurine was modeled in Fusion 360, printed and then molded and cast. Several light layers of paint were applied to get that Fallout metal look.

Prop: Shop – Hearthstone Box

Britt and Bill made a prop Hearthstone Box! This build involves 3D Printing, lots of sanding, fake wood grain, molding and casting, box building, and metallic finishes.
