Make high-volume production molds Directly from CAD/CAM and Rapid Prototyping models Fast without risk of damage from heat or pressure. VLT® brings to manufacturers what has been missing so far inthe CAD/Cam revolution - speed! Get your models into production in as little as 30 minutes!
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! 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 0.1%. 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. Special note about shrinkage rates:
The figures given for this and all other rubber molding compounds are for the rubber mold itself, not the wax pattern it produces or the final casting produced from the wax pattern. The same rubber compound molded around the same metal master model can produce highly variable final casting shrinkage rates depending on the moldmaker
& caster’s skill, knowledge, precision and attention to detail. Final casting shrinkage is the result of the jewelry manufacturer’s procedures. Strips measure 18" x 2 7/8th" x 1/8th" (45.7 cm x 7.3 cm x 3 mm). 5 lb. strips. Instructions.
