ISO 3302-1 for RTV Silicone Molds: A Drawing Class
ISO 3302-1 is a rubber drawing class, not "precision." For RTV trays, separate jacket, pocket, and casting. Don't paste ISO 2768 on a 20A lip.

Liquid Silicone Rubber Molding vs RTV Cavities
LSR molding is platinum liquid injected into a hot tool - finished parts are an HTV product or mold RFQ here, or a different LSR-tool RFQ - ask us. RUUIPON RTV cavities stay here. HTV/HCR mold tools stay on RUUIPON.

How to Extend Custom RTV Silicone Mold Life
RTV life is tear, swell, UV, and a warped support shell - not an SPI shot count. Recast against a living mother. We do not sell a cycle warranty.
