HOBEN International: White Label

Castaldo Jewelry Molding Rubber has been the industry standard for more than 40 years and continues to be the best jewellery moulding rubber available for lost wax casting.

Castaldo White Label has a high concentration of pure natural gum rubber which makes it soft and pliable, qualities that the experienced mould cutter values in his efforts to produce high-quality moulds in the shortest reasonable time.

The compound is unique in consistently allowing one to cut with the knife, not ahead of it, a small but important detail that allows the mould maker complete control.

The care and labour invested in a Castaldo rubber mould can last for decades. The mould will retain its characteristic “memory” and flexibility long after other mould rubbers have become crumbly and stiff.
