For those of us beginner and veteran dice makers who have tried to use some form of cap molds, you know there is a love and hate relationship with them. I started my dice making journey with sprue molds, but I just did not like the extra work it took to clean up the dice after a pull.
For the longest time I could not wrap my head around how to make a cap mold. With sprue molds you needed the sprue and overfill areas to not only pour in your resin, but to also help with escaping bubbles. Around the same time that I started my research the amazing Dice Witchery published a YouTube video on creating Cap Molds, AND it was a game changer.
With this method there was very little cleanup needed, the supplies were minimal and the instructions were easy to follow.
- Rubber/Nitrile Gloves
- Small Plastic Cups (Dice Witchery used 3 oz)
- 3″ Packing Tape (Thinner packing tape can be used, but will need 2 overlapping pieces)
- Hot Glue Gun
- X-Acto Knife
- Small object for making keys (Keys are a way for your cap to lock into place)
- Master Dice
Since this video Dice Witchery has published more Cap style mold videos to include using PVC Cap Molds, as well as tips and tricks for Pouring Dice with Cap Molds. Make sure to show some love and support for Dice Witchery by subscribing to their YouTube channel and give them a follow on their socials.
One thing I have recently changed is going from single dice molds to more of a slab mold. You can find some good videos on making the slab/cap molds below. What really got me excited for the slab mold was the TaCrow mold system which you can find at https://www.etsy.com/shop/LilTaCrowShop. This mold system allows you to not only have built in keys for your slab mold but all sides of your container are easy to put together and take apart. It really is an amazing game changer and I have saved a lot of silicone by using this system.
