Silicone and polycarbonate are different mold materials with different handling characteristics. The right choice depends on formulation, release method, production equipment, required rigidity, surface finish, and cleaning process.
Silicone molds
Silicone molds are flexible, which can assist demolding and make them useful for many gummy shapes and production methods. Performance varies by silicone formulation, hardness, cure system, post-curing, mold thickness, cavity design, and process conditions.
Polycarbonate molds
Polycarbonate molds are rigid and are widely used where dimensional rigidity and a hard polished surface are important, including many chocolate processes. Suitability for gummies depends on release behavior, formulation, equipment, and mold design.
Key comparison points
- Flexible versus rigid handling
- Demolding method
- Surface finish
- Equipment, frame, and conveyor requirements
- Cleaning method and approved chemicals
- Temperature limits from the exact material supplier
- Food-contact documentation for the exact formulation
Do not rely on material name alone
“Silicone” and “polycarbonate” describe broad material families. Confirm the exact grade, intended use, temperature range, cleaning limits, and supporting documentation. Test the complete production process before scaling.
