Castaldo Econosil® Jewellery Moulding Silicone Rubber Strip


Econosil is a putty-like material that makes strong production rubber moulds. Moulds made of Castaldo Econosil cut like butter, give waxes with a high shine finish and require no messy sprays or powders.

Castaldo Econosil® Jewellery Moulding Rubber is a harder, firmer but still flexible version of the Super High Strength™ rubber, at a lower cost. Which mean the moulds produce less variation in final cast weights, as well as greater detail and less distortion. Rubber shrinkage is only 1.1%
