    摘要: In order to provide a method for the radiation-crosslinking of elements (16) made of a radiation-crosslinkable plastics material, with which the radiation-crosslinking can be carried out more easily and cost-effectively than to date in terms of operating procedure, it is proposed that said method comprises the following steps of: placing one or more elements in a packaging unit with a receptacle (20) for the one or more elements, wherein the receptacle is produced from a poorly heat conducting material; heating the elements contained in the packaging unit to a temperature which is equal to or greater than a predetermined crosslinking temperature; introducing the heated elements in the packaging unit into an irradiation device for the radiation-crosslinking of the plastics material; and removing the packaging unit with the elements from the irradiation device following the radiation-crosslinking.

    摘要: A method for making an ultra-high weight polyethylene (UHMWPE) medical implant starts with obtaining a preform consolidated from UHMWPE resin. Thereafter the preform is hot isostatically pressed at a temperature between 150°C and 190°C at a pressure up to 30,000 psi. After the hot isostatic pressing the preform is sequentially irradiated in a solid state at a total radiation dose of 2 to 10 MRad. The irradiated UHMWPE preform is then heated to a temperature of about 110°C to about 190°C for between 2 to 10 hours. The irradiated and heated preform is then cooled after each irradiation and heating to at or below 50°C, and thereafter a medical implant is formed from the preform. Alternately, the process can be performed on the medical implant itself.

    摘要: The present invention generally relates to a method for making colored contact lenses, in particular to colored silicone hydrogel contact lenses. The present invention is also related to a method of a first high intensity UV curing the colored print on the mold and a second high intensity UV treating mold for making colored silicone hydrogel contact lenses. The present invention illustrates the right combination of the first high intensity UV exposure and the second high intensity UV exposure allows a lens that maintains good ion permeability (IP) value and a good print quality.
