Castaldo Econosil

Castaldo Econosil® Jewelry Molding Rubber is a harder, firmer but still flexible molding rubber. Firmer molds mean less variation in final cast weights, greater detail and less distortion. Molds compress less during injection and thus avoid squeezing off wax flow through thin channels. It’s ideal for filigree and other fine details. Rubber shrinkage is only 1.1%. Econosil® is a putty-like material that makes strong, tough, production rubber molds.   Molds made of Castaldo® Econosil® cut like butter, give waxes with a high shine finish and require no messy sprays or powders.
