New developments for vacuum preparation and casting according to the automatic pressure gelation process at elevated temperatures

摘要

This lecture 1st essentially divided into two main groups: The subject,,Continuous vacuum preparation" presents a new development that allows to completely degas cast resin in a single passage for further processing under vacuum. The equipmentcan be used for both low-viscous and extremely high- viscous cast resin.In the automatic pressure gelation process for the production of insulating parts for the electric industry, the additional preheating of the cast resin compound allowed to achieve a majoe reduction of cycle times by up to 50 %. New developments in theequipment range for the application of this process by DUO pressure accumulator and ultra-fast-compound (UFC)-heater will be explained in detail and examples will be given.
