Application optimized compression induced solidification
In this investigation, a possibility for shortening the cycle time in the manufacture of thick-walled optical components by compression induced solidification (CIS) was studied in a numerical manner and experimentally tested for validity. The test specimens produced with a reduced cycle time were compared with the manufacturing processes commonly used for such components, i.e. injection molding, injection-compression molding and conventional CIS, with regard to dimensional accuracy, internal stresses and microstructural impression. It could be shown that by delaying the heating of the mold, the adapting time and thus the cycle time of the process can be reduced by up to 55 %, while maintaining the same high quality of the components.
