Mold Max 60 – High Heat Resistant Silicone
Mold Max 60 is a Shore 60A tin-catalyzed silicone mold rubber designed for high-heat applications up to 560°F (294°C). Working time is about 40 minutes with a 24-hour cure window. Hardness is 60A, and the mix ratio is specified as Part A & B combined by weight. This makes it well-suited for artisans creating durable molds for hot resins, waxes, or other heat-stressed casting media. Choose this when long demold life and strong heat resistance matter most, especially for recurring production runs.
Best for: professional mold makers and serious hobbyists needing heat resistance and sturdy mold structure. Limitation: handling requires attention to proper mixing and cure conditions to achieve optimal performance.
ResinWorld Skull Molds Set
This set includes large, medium, and small skull silicone molds made from clear, flexible silicone. The clear material helps you monitor resin flow and bubble formation during casting. The set is designed for resin, soap, clay, and candle wax casting, with the expectation that the finished pieces are glossy and vibrant. Best for: Halloween decor, goth-inspired crafts, and quick multi-size skull projects. Limitation: finished pieces and accessories pictured are not included, so you’ll need to source additional supplies separately.
LET’S RESIN Dragon Molds, 3 Pcs
These dragon molds feature baby dragons with a playful “hear no evil, see no evil, speak no evil” motif. They’re designed for easy demolding and glossy finishes, using premium silicone for flexibility and durability. Best for: resin artists seeking charming character pieces and relatively simple demolding. Caution: avoid direct heat or torches near the mold to prevent damage; use proper bubble reduction tools during casting.
LET’S RESIN Turtle Shape Molds
This large sea turtle mold measures about 5.2 by 6.5 by 2 inches and accommodates roughly 8.7 oz of epoxy resin. It preserves detailed shell texture and offers high transparency for placement planning. Best for: large ocean-themed pieces, lamp accents, or decorative bowls. Limitation: mold design may accumulate air bubbles at the tail and shell edges, so extra attention to bubble control is advised.
Let’s Resin Axolotl Molds, 3D Silicone
The axolotl mold measures 7.06 x 4.39 x 2.17 inches with a recommended 4.5 fl. oz resin. Detailed features include six horns and four claws, creating a distinctive resin piece. Best for: artists seeking a whimsical, highly detailed character mold. Limitation: avoid using heat guns directly on the mold as heat can damage the silicone; demold gently to maintain shape integrity.
Buying Guide
What should you consider when choosing a high-temp silicone mold?
- Heat resistance: Confirm the maximum temperature the mold can withstand and ensure it matches your casting media.
- Shore hardness: Affects detail retention and flexibility; 60A is common for sturdy but flexible molds.
- Demold ease: Transparent or glossy interiors aid bubble management and reveal mold geometry clearly.
- Size and shape variety: Sets with multiple sizes offer versatility for different projects.
- Durability and reuse: Look for premium silicone with good tear strength for repeated use.
- Special features: Clear molds help monitoring resin flow; detailed character molds add unique appeal.
Practical tips for successful use include proper mixing ratios, avoiding overheating during demolding, and gentle handling to preserve mold integrity. Choose sets that align with your typical project scale, whether you produce small trinkets or large decor items, and consider whether you prefer clear interiors for visibility or vivid color outcomes from opaque interiors.
