Production of  molds:

1Clean the master pattern and drying in air, for smoothprocessing(To play with a layer of mold release wax or brushing again release agent) 2 500-1000 grams of silicon rubber mold into plastic pots spare; 3 Added to the vessel for mixing the hardener at a weight ratio (typically 1.5-2.5%) weighed and sufficiently stirred to uniformity; 4 As the case (especially the first layer) adding a certain amount of silicone diluents.Until blended, generally 3 to 5 minutes. 5 silicone rubber mold and curing agent mixed, reaction was carried out at room temperature, and the release of a low molecular weight alcohol, Alcohol molecules from colloidal required under negative pressure discharge bulbs 1-3 minutes. 6 the multilayer brushing piece mold, should follow the inner, middle and outer curing appropriate. Dosage of curing agent is relatively small, longer reaction time, reaction, colloid, so the best dosage of curing agent is less in more, to be the first layer dry and then brush when brushing second layer. The operating time of 30-50 minutes, the removal time of 10-15 hours, Curing time of 24 hours, 7 the three-dimensional perfusion model, generally 10 to 15 hours curing. 8 Even after the completion of the soft mold making production of gypsum or glass fiber reinforced plastic jacket to support soft silicone mold.
