Silicone Jewelry Molding Rubber
Castaldo Products MFG's silicone jewelry molding rubbers create durable, high-precision molds with exceptional thermal conductivity. These materials produce smooth wax patterns that release easily without powders or sprays, reducing production time. Ideal for vacuum wax injectors, they maintain dimensional stability while offering superior memory and resistance to tearing during complex mold creation.
Natural Jewelry Molding Rubber
Our natural rubber formulations provide flexible, resilient molds with high pliability for intricate jewelry designs. Available in 5lb and 50lb rolls, these materials excel at capturing fine details while maintaining durability. The Gold Label variant contains enhanced natural gum rubber for superior performance in challenging undercut applications.
RTV Jewelry Molding Rubber
Room Temperature Vulcanizing silicone compounds create flexible molds with zero shrinkage characteristics. These liquid formulations cure at varying temperatures to accommodate different production requirements, from rapid prototyping to high-volume manufacturing. Specialized versions offer transparency for visual injection monitoring and accelerated curing cycles.
Injection Waxes
Castaldo Products MFG's injection waxes produce durable, flexible patterns with excellent memory retention. Our formulations include additives like Golden River to enhance flow properties while maintaining structural integrity. These materials enable efficient production of complex jewelry components with minimal post-processing requirements.
Jewelry Mold Release Spray
Our silicone oil-based mold release spray facilitates easy wax pattern extraction from rubber or metal molds. The aerosol formulation provides even coverage without residue buildup, maintaining mold integrity while reducing cleaning time between production cycles.
