Stunning surface finish and high definition for jewelry pieces prototyping and production with RTV/silicone molding

Figure 4 JEWEL MASTER GRY is a versatile master pattern material for high volume jewelry RTV/silicone molds and for prototype/fit models. The material’s high heat deflection temperature (300°C) ensures compatibility with a range of silicones for creating molds used in jewelry casting production workflows.

This material also delivers exceptional precise surface quality for design and functional prototyping, as well as snap-fit and stone-in-place testing. Figure 4 JEWEL MASTER GRY meets biocompatibility standard ISO 10933-5 for cytotoxicity, making it safe for try-ons and fittings.
