Castaldo Econosil® Jewelry Molding Rubber is a harder, firmer but still flexible version of our Castaldo Super High Strength™ silicone jewelry molding rubber at a lower cost.
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%
Just like our Castaldo Super High Strength jewelry molding rubber, 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. Waxes self-release easily.
Econosil is the fast & easy way to mold and cast almost anything in metal. Use it to make:
Econosil withstands temperatures up to 660°F/ 350°C. It can be used to cast lead, pewter, tin, zinc and other low temperature melting alloys.
