Analysis of the injection overmoulding process for polymer lenses by use of a specially designed mould
Abstract
The form accuracy of injection moulded polymer optics that can be used for various applications such as illumination with LEDs is always influenced by shrinkage. The production of such optics in two steps by using the injection overmoulding process is described and analyzed as a means for significantly reducing the shrinkage of the final polymer part.
