KISREL Large Rectangular Resin Molds
These large rectangular deep pour silicone molds come in three sizes: 9.8″ x 6.7″ x 2″, 7.7″ x 4.5″ x 0.8″, and 6.5″ x 4.5″ x 0.8″.

Best for aspirational crafters who want multiple sizes from a single purchase. Caution: larger pours may require longer cure times and careful air-release to avoid bubbles. Best for: large decorative pieces and wedding keepsakes; avoid if you need very thin pours.
RESINWORLD 6-Cavity Deep Round Coaster Molds
This six-cavity round set yields 3.93″ diameter coasters with a 0.82″ depth. The shiny silicone surface creates a mirror-like finish that reduces finishing work. Demolding is straightforward, and the molds are reusable for multiple projects, including flower bouquets and small trays. Best for: makers who want glossy finishes without post-polish; better for coasters than large panels; caution: round coasters limit some custom shapes.
2 Pack Rectangle Silicone Molds for Epoxy Resin
This set includes two sizes: 7″ x 3.4″ x 2.4″ and 6.1″ x 2.2″ x 2″. A wooden stand helps maintain mold shape during curing, supporting well-presented results. The included design makes demolding easier, reducing damage risk for complex embedded items. Best for: projects needing varied dimensions and stable molds; better for desk decor or wall art; caution: wood stand can affect heat distribution for very thick pours.
LET’S RESIN Extra Deep Resin Coaster Molds
With a 0.8-inch deep cavity, these round coasters support larger fillers like wood slices and flowers. The molds are designed for versatility beyond coasters, including paperweights and keepsakes. They are noted for a glossy interior that reduces polishing work. Best for: resin artists seeking depth and standout coasters; choose this if you want larger embellishments; caution: only one mold in the package, limiting variety.
GYBOHO 12-Cavity Extra Deep Coaster Molds
This set provides 12 cavities across round and square shapes, each about 0.82″ deep and 4″ across. The dual shapes enable visually varied collections, from wedding bouquets to insect specimens preserved in resin. The glossy interiors facilitate a smooth finish without excessive polishing. Best for: bulk coaster production or mixed-shape displays; better for larger batch projects; caution: more mold variety means more planning for curing times.
Buying Guide: Deep Pour Molds For Resin Projects
What should you consider when choosing deep pour epoxy molds? Here are practical factors to guide your decision:
- Depth and capacity: Choose molds with enough depth for your intended fills; deeper cavities enable thicker, more dimensional pieces like river-table panels or robust coasters.
- Material and durability: Look for high-quality silicone that remains flexible after cure and resists tearing under repeated use.
- Form factor: Rectangular and round shapes serve different projects; combine sets to cover large surfaces and small keepsakes.
- Demolding ease: Molds with smooth interiors and built-in supports reduce risk of damage during removal, especially for embedded elements.
- Cleaning and reuse: Silicone molds that resist staining and are easy to clean save time on future pours.
- Embedded materials compatibility: If you plan to embed wood, flowers, or small objects, ensure the mold supports thick pours and provides stable alignment.
Practical tips for best results
- Seal edges and use mold releasing agents if necessary to maximize demolding success.
- Pour in stages for very deep cavities to prevent heat buildup and bubble formation.
- Degas resin before pouring if your project includes many inclusions or flowers.
- Plan curing times around ambient temperature to maintain dimensional stability.
Common questions about deep pour epoxy molds
- What makes a deep pour mold different from standard molds? Deep pours accommodate thicker layers and larger embeds, creating multidimensional pieces.
- Are these molds suitable for river tables? Large rectangular and deep cavities can support portions of river-table style projects, depending on resin volume used.
- Can I use these molds for materials other than epoxy resin? Yes, many are compatible with plaster, wax, soap, polymer clay, and gypsum.
- How do I ensure a smooth finish on cured pieces? Use mold interiors with a glossy surface, and consider a light polish only if needed for transparency or clarity.
- Do these sets include multiple sizes? Several sets offer two or more sizes to cover a range of projects, from coasters to large panels.
- Is demolding difficult with deep pours? Proper flex and gentle twisting usually makes demolding straightforward, especially with high-quality silicone.
