Abstract

Üblicherweise werden Polplatten für Bleibatterien gegossen, jedoch werden aufgund des Umwelt- und Arbeitsschutzes und zur Senkung des Herstellkosten alterative Herstellverfahen gesucht. Als mögliche Herstellvariante wird in dieser Anteil das Kaltfließpressen betrachtet. Dazu wurde mit Reinblei und PbSb (3.5%)-Legierung Fließkurven bei unterschiedliche Temperatur aufgenommen. Weiters wurden vereinfachte Fließpresswerkzeuge gebaut und Extrusionsversuche durchgeführt. Die Auswertungen und die Verfahrensvergleiche haben gezeigt, daß die Polplatte prinzipiell mit Kaltfließpressen herstellbar ist. Im Ausblick werden auch Hinweise zur Verbesserung des Fertigungprozesses angegeben.
