Make high-volume production molds Directly from CAD/CAM and Rapid Prototyping models Fast without risk of damage from heat or pressure.
Castaldo VLT (Very Low Temperature) brings to manufacturers what has been missing so far in the CAD/CAM revolution -Speed! Get your models into production in as little as 30 minutes!
Castaldo VLT vulcanizes at temperatures as low as 160° F / 71° C, making it ideal for creating tough, strong long-lasting production rubber molds directly from all types of plastic resin models. makes great molds from traditional wax carvings too!
Castaldo VLT produces highly detailed wax injections with an extrodinarily shiny surface that requires less finishing. Waxes are self-releasing and need no release spray. Molds are easy to pack and easy to cut. Rubber shrinkage is only 1.4%.
Castaldo VLT Silicone Molding Rubber is provided in two convienient sizes. Regular: Strips 18" x 2 7/8" x approximately 3/8" (45.7cm x 7.3cm x approcimately 6mm) and packaged in 5 lb. cartons (2.27 kg). Double Wide: Strips 18" x 5 3/4" x approximately 3/8" (45.7cm x 14.5cm x approximately 6mm) and packaged in 10 lb. / cartons (4.5 kg).
A standard size mold vulcanizes at: 88°C / 190°F for 30 minutes, 82°C / 180°F for 45 minutes, 76°C / 170°F for 60 minutes, 71°C / 160°F for 90 minutes.
