Castaldo - ready made molds

Castaldo White Label^®, the less expensive and firmer of our two grades, has a high concentration of pure natural gum rubber, which makes it resilient and pliable, qualities that the experienced mold-maker values in his efforts to produce high-quality molds in the shortest reasonable time.

Castaldo Gold Label^® contains even more pure natural gum rubber, making it even softer and more pliable. Experienced mold-makers know that this compound’s superior qualities can save them substantially on labor costs when used for difficult molds containing undercuts, where a stiffer mold would break delicate wax patterns or would make their production impossible altogether.

Castaldo No Shrink Pink Jewelry Molding Rubber is designed to be either compatible with White Labe®l and Gold Label® Jewelry Molding Rubber or as similar as possible. Handling, procedures, etc. are identical with those commonly used for White Label and Gold Label Jewelry Molding Rubber except that special attention must be paid to accurate vulcanizing temperatures. 

Castaldo Titanium Label jewelry molding rubber packs, cuts, bends, flexes and stretches just like our standard White Label® and Gold Label® rubber. Castaldo Titanium Label jewelry molding rubber is a natural rubber product similar to our famous White Label & Gold Label. Vulcanizing time and temperature recommendations are identical.
