Innovative Processing Methods & Technologies for Liquid Silicone Rubber

Dr. Grindling graduated from the Montanuniversität Leoben in Austria with a Degree in Polymer Engineering and Science. Later, while working, he completed his Doctorate in Mechanical Engineering from the University Paderborn in Germany and his MBA from the University of Zurich in Switzerland. He was employed for 20 years with Ciba Geigy/Novartis, Ciba Specialty Chemicals and Huntsman Advanced Materials in positions such as Technical Service Engineer, Head Application Technique Power, Manager Processing & Testing and Technology Manager Composites. He joined Vogel moulds and machines AG in 2018.

Silicone insulation materials for MV & HV electrical components face high loads in operation and must be free of defects. Air inclusions, voids, flow lines, impurities and cracks are all deficiencies that can lead to failures due to partial discharge and mean potentially high reject rates during manufacture. This presentation will review the scope of machines that allow components to be individually designed and adapted to the characteristics of their application – from mixing and dosing systems to degassing and filtering devices to pre-heating units to moulds to clamping machines to automated handling systems.
