This 8x8x3" block mold is perfect for casting items such as flowers, rocks, and other memorabilia into resin up to 3" thick. It's an ideal size for resin encased models and sculptures.
The 3" depth and 8x8 footprint of this silicone mold also makes it ideal for making resin and wood blanks for wood turning to create resin and wood bowls.
This is a popular mold for creating small resin table lamps (turning the cast piece on its side to create an 8" wide x 8" tall and 3" front to back piece). Simply install an LED light on the bottom of your casting and up-light it from below. Works great with LED puck lights, and thin battery powered light strands.
Note that due to the stiffness of the silicone, demolding a piece of this height can be challenging. There are two ways to remove castings from this mold as peeling back the mold significantly will likely result in tearing.
1. Pouring distilled water between the cured resin piece and the interior wall of the mold and moving the water around the resin casting before trying to attempt to remove it from the mold.
2. Using a compressed air hose with a soft (plastic or rubber) gun nozzle end. Insert your air gun in between the casting and the mold wall and scale up the air flow rate until the casting rises from the mold.
Crafted Elements Silicone Molds
The last mold you will ever need. Created just for makers, resin artists and wood workers, these time saving flexible yet durable silicone molds significantly cut down on the setup and demolding time usually involved with other molds. Silicone molds are superior to wood and tuck tape, and HDPE molds because:
- They can be used with epoxy resin, resin and wood, concrete, Jesmonite, plaster and more.
- They never need assembled, or disassembled. Saving huge amounts of time.
- The strength and flexibility of the molds allows you to insert and remove pieces of wood easily.
- The corners and edges never need sealed.
- When using wood, the wood stays in place, tight in the mold if you cut it 1/16" larger than the width of the mold. Alternatively use our HDPE block kit in conjunction with hand weights or clamps to keep your wood from up in your resin. The HDPE blocks dont stick to set resin and are easily and cleanly removed.
- The mold is heat resistant to ~450F. Avoid direct contact with the flame of a torch. Briskly wave your torch or use a heat gun to pop bubbles.
- The molds are reusable. However silicone molds do have a finite lifespan when used with epoxy resin, but getting 20-30+ castings out of the mold can be expected when they are properly cared for and a non-silicone based mold release spray is used.
- Like HDPE, epoxy resin does not stick to silicone. However, the heat generated by the exothermic reaction and the chemicals in epoxy resin are very harsh to all silicone molds. Additionally, if part of your epoxy has not fully set due to improper mixing, the epoxy can become bonded to the mold. Both of these factors can lead to mold tear out when removing your piece from the mold, leading to pits and tears on the surface of the mold. This is why we a non-silicone based mold release spray is required before each pour. To help prevent tear out and to increase the life of your mold. We use the 'MG Chemicals 8329 Non-Silicone Epoxy Mold Release', 'Mann Ease Release 200' or 'Mann Ease Release 300'. Cooking spray, vaseline, silicone based sprays or sprays designed for urethane or polyester products should NEVER be used. Using a proper, non-silicone based mold release can mean the difference between getting only a couple of uses from your mold to 20, 30 or more.
