Ring Mold Silicone, Oval Split Form | Resin | Size 6-7 | Beginner Casting Tool

While most ring molds are made to be straightforward, this one is designed as a split form that can help reduce added sanding and polishing. This ring mold silicone is a beginner-level casting tool made for fresh, clean-made-to-order use, and it comes in an opaque silicone option that is flexible and long lasting. It is made for casting ring bands in size 6-7, and the split design will leave a seam on the inside palm side of the band that may need sanding, especially with clear resin.

• Beginner difficulty level with a split mold design that helps simplify casting
• Size 6-7 ring form; please read the expanded listing description or check the listing photos for caliper measurements in mm
• Opaque silicone is economical, flexible, and rated for use from -65°F to 400°F (-19°C to 205°C)
• This jewelry casting mold can be used for urethane, epoxy, polyester resins, wax, soap, gypsum/concrete, low melt alloys/metals, and polymer clays
• Split molds may leave a seam and occasional scratches on the inside of the palm side of the band, so seam sanding needed may apply

Please note that the opaque silicone is not compatible with UV resin. The clear version is also mentioned in the listing details for buyers who want to see into the mold while casting, but extended use and high heat can eventually cause clouding even though the casts remain shiny. Mold life will depend on care, the casting material used, the amount of heat applied, and abrasive materials such as concrete.

If you are comparing materials, there are two silicone options available: opaque and clear. The opaque version is economical, flexible, long lasting, and not compatible with UV resin. The clear version is made with a platinum base, is food safe, and lets you see into the mold while you adjust your casts. The physical lifespan and number of casts depend on mold care, the casting material used, heat exposure, and whether the material is abrasive. Heat from ovens or flames can reduce lifespan, and high heat producing resins may also shorten use, while abrasive materials such as concrete can erode fine detail over time. The silicone can be used at temperatures from -65°F to 400°F (-19°C to 205°C), and the clear option may eventually cloud with extended heat exposure while still leaving casts shiny.
