Mold Making

At ZPC we offer Castaldo® LiquaCast® 0% shrinkage for molding.

LiquaCast® is a 0% shrinkage room temperature vulcanizing liquid rubber that lets you make molds of delicate objects that would not survive the heat and pressure of the normal vulcanization process. Typical uses include making molds of CAD-CAM, RP and SLA resin models, wax carvings and wax injections. Also possible are objects from nature — leaves, plants, flowers, fruit, insects – anything!

Castaldo® LiquaCast® is an easy-flowing two-part liquid room temperature vulcanizing compound that makes tough, strong, flexible rubber molds in 18 hours at normal temperatures. It can be cured in as little as 90 minutes at temperatures up to 66° C./ 150° F.
Unlike traditional silicone liquid molding rubbers, LiquaCast is easy to pour, easy to mix and easy to vacuum de-bubble because of its low viscosity.

Molds made of LiquaCast are much stronger, tougher and longer lasting than those made from traditional liquid rubber compounds. LiquaCast molds are production molds that can be used 100’s of times, not intermediary or prototype molds that can be used only once or twice.
