Both parts are liquid but one part contains the catalyst which is platinum. Liquid Silicone has the consistency of cold molasses, is naturally translucent and comes in either pail kits (approx. 80 lbs.) or drum kits (approx. 800 lbs.) The two parts are mixed and delivered to the barrel of the injection press via a mixing/metering pumping system. If desired, Pigment may be added via a pumping system to color the Liquid Silicone. The mixed Liquid Silicone is then injected into the mold much like gum stock, but the Runner, Gate and Sprue are generally smaller due to its lower Viscosity. Once in the mold, the Liquid Silicone cures at a much faster rate than typical high consistency Silicone due to its platinum cure system. As a result of this rapid cure cycle, the part price is frequently lower than parts made using conventional molding processes such as Compression, Transfer and Injection Molding.
