          Abstract

          Intense competitive environment and customers' changing demands and needs apply temporal and financial pressure to product development process. For this reason interest in design and innovation is inevitable. Reducing project duration also affects further applications as well as new tooling materials and methods become more important to catch up project schedule. Conventional methods of stamping process usually do not suit to prototype or low volume production in terms of project schedule and cost. In this study a polymer metal carcass die structure was introduced in order to stamp large sheet metal prototype parts. Dimensional conformance of prototype sheet metal parts was compared with actual production and as a result polymer metal carcass die method is an effective method for prototype sheet metal parts to meet the tolerance interval. Therefore, this method is cost effective and helps to meet the project schedule in time.

          Kurzfassung

          Das intensive Wettbewerbsumfeld und die sich ändernden Kundenanforderungen und -notwendigkeiten üben zeitlichen und finanziellen Druck auf den Produktentwicklungsprozess aus. Deshalb gibt es zwangsläufig das Interesse am Produktdesign und an Innovation. Die Reduzierung der Projektlaufzeit beeinflusst auch weitere Anwendungen, darüber hinaus werden neue Werkzeugmaterialien und Verfahren zur Einhaltung des Projektplans immer bedeutender. Konventionelle Verfahren des Stanzprozesses sind üblicherweise hinsichtlich des Projektplans und der Kosten nicht für Prototypproduktion und geringe Stückzahlen geeignet. In der diesem Beitrag zugrunde liegenden Studie wurde eine Polymer-Metall-Rumpfform eingeführt, um große Blechprototypteile während des Wartungsintervals der Prototypwerkzeuge zu pressen. Die Übereinstimmung der Dimensionen der Prototypblechteile wurde mit der aktuellen Produktion verglichen und es zeigte sich, dass das Polymer-Metall-Rumpfformverfahren eine effektive Methode ist, das Toleranzintervall zu erfüllen. Darüber hinaus erbringt das während der Wartung durchgeführte Verfahren einen Kostenvorteil wobei der Projektplan eingehalten werden kann.
