Publication number: 20100327470Abstract: The invention relates to a process for producing plastic components, in particular optical lenses or optical light-guides, wherein plastic melt is injected via a sprue (3, 4, 6, 8) into a cavity (1) of a moulding tool shaping the component and additional plastic melt is after-pressed into the cavity (1) for the purpose of compensating a volume contraction of the injected plastic melt due to cooling. The process is characterised in that the plastic melt located in the sprue (3, 4, 6, 8) is kept flowable by means of energy introduced in the region of the sprue until such time as the molten core of the plastic component has solidified in the course of the after-pressing of plastic melt for the purpose of compensating the volume contraction due to cooling (holding-pressure). The invention further relates to an apparatus for implementing the process.Type: ApplicationFiled: June 25, 2010Publication date: December 30, 2010Applicant: Bayer MaterialScience AGInventors: Rainer Protte, Christoph Klinkenberg
