摘要
The method comprises: controlling temperature of a liquid, light-activatable silicon material depending on its composition; cross-linking the material by UV and/or visible radiation before the material enters mold cavity(1); preheating the material at 45-50[deg] C; and activating the material inside the mold cavity and/or inside a feed line (3) to the mold cavity by the UV and/or visible radiation. The UV and/or the visible light originates from radiation sources (5) which are arranged: inside pocket holes in a transparent material (4) of the mold cavity; and/or the feed line to the mold cavity. The method comprises: controlling a temperature of a liquid, light-activatable silicon material depending on its composition; cross-linking the material by UV and/or visible radiation before the material enters a mold cavity(1); preheating the material at 45-50[deg] C; and activating the material inside the mold cavity and/or inside a feed line (3) to the mold cavity using the UV and/or visible radiation. The UV and/or the visible light originates from radiation sources (5) which are arranged: inside pocket holes in a transparent material (4) of the mold cavity; the feed line to the mold cavity; and/or inside passages which are closed on one side in the mold cavity and/or the feed line to the mold cavity. The radiation sources are led in close proximity to the silicon material. A cycle rate of cross-linking duration is 10-15 seconds. Independent claims are included for: (1) an apparatus for processing a liquid, light activatable silicon material; and (2) an injection-molding machine.
