What the AI looks for in Jewelry Resin Casting Molds
- Shiny versus matte cavity
- Choose molds with a polished cavity if you want glossy pieces without sanding or a top coat Resin copies the mold surface exactly, so a matte cavity produces a frosted piece.
- Silicone cure type
- Prefer platinum-cure silicone molds Platinum-cure silicone resists tearing and holds its shape better. Some tin-cure molds can inhibit resin curing or degrade faster.
- Wall thickness and rigidity
- Walls stiff enough not to bow when filled Thin, floppy molds bulge under the weight of resin, distorting flat backs and edges.
- Resin compatibility
- Check the mold is suitable for both epoxy and UV resin if you use both UV resin must be cured through the mold or open face. Some opaque molds block the UV light.

What to avoid

Questions
Do silicone molds need a release agent?
Generally no for epoxy and UV resin. A release spray can extend mold life, but it may dull a glossy finish.
