Castaldo

Castaldo has been a major part of jewelry casting since the industry's beginnings in the late 1940's. Castaldo natural rubber products, which include White Label, Gold Label and No Shrink Pink jewelry molding rubber in a variety of convenient sizes and forms, are made from the latex sap of rubber trees grown on plantations in the rain forests of South East Asia. The sap is collected daily from each tree in a small cup.
Other Castaldo rubber molding products, such as our Super High Strength and Econosil silicone molding rubber and LiquaCast liquid rubber, are based on man-made products produced by the chemical industry.
