Abstract
An apparatus and a method for processing liquid, light-activatable silicone materials of low viscosity by way of injection-molding technology, and an injection-molding machine operating in accordance with the method, in which the cross-linking of the silicone material is activated by the effect of ultraviolet and/or visible radiation.
Claims14
An apparatus configured to process a liquid, light-activatable silicone material of low viscosity, comprising:
- a mold cavity;
- a feed line fluidically connected at one end to one or more storage containers for the liquid, light-activatable silicone material of low viscosity and at another end to the mold cavity;
- a temperature control unit to control the temperature of the liquid, light-activatable silicone material,
- wherein a region of the feed line directly adjoins the mold cavity and is widened and flattened out, at least a part of the flattened region of the feed line comprises a transparent material that includes pocket holes, and one or more radiation sources configured to provide ultraviolet or visible light are provided inside the pocket holes in the transparent material.
An injection-molding machine having an injection-molding tool for the production of molded silicone products from light-activatable silicone materials of low viscosity, comprising:
- a mold cavity;
- a feed line fluidically connected at one end to one or more storage containers for the liquid, light-activatable silicone material of low viscosity and at another end to the mold cavity;
- a temperature control unit to control the temperature of the liquid, light-activatable silicone material;
- wherein a region of the feed line directly adjoins the mold cavity and is widened and flattened out, at least a part of the flattened region of the feed line comprises a transparent material that includes pocket holes, and one or more radiation sources configured to provide ultraviolet or visible light are provided inside the pocket holes in the transparent material.
