Today’s manufacturing industry requires product data management system (PDM) for efficient product development and production. Manufacturing industries must deal with competition, time to market, reduction of the cost of doing business, and rapid development of new services and products. To address these requirements industries must constantly reconsider and optimize the way they do business an...

K e y w o r d s F i l m casting, Longitudinal stretching, Transverse stretching, Modelling industrial processes. 1. I N T R O D U C T I O N Film casting (Figure 1) is a widely used manufacturing process for polymeric films production; other processes are blow casting and extrusion, now generally used for the production of low quality films. A general overview of fihn casting and other analogous...

D. Novoselović, I. Budić, I. Samardžić, Mechanical Engineering Faculty in Slavonski Brod, University of Osijek, Croatia The influence of technological parameters on residual stresses in pressure die castings is analysed in this paper. In order for the residual stresses to be as low as possible the optimization of technological parameters is necessary. The centrally composed plan of experiment 2...

Kurzfassung. Die Nadelpunktion ist ein etabliertes Verfahren für die minimal-invasive Behandlung von Läsionen in der Leber. Nadelpunktionen werden präzise anhand von CT-Daten des Patienten geplant, um das Risiko einer Komplikation zu minimieren. Die vorliegende Arbeit hat die Planung von Nadelpfaden anhand von 4D-Bilddaten bei Punktionseingriffen unter Berücksichtigung der durch die Atmung herv...

Techniken der Volumenvisualisierung werden zur räumlichen Darstellung dreidimensionaler Skalarfelder benötigt, wie sie beispielsweise in der Medizin in Form von tomographischen Schnittbildern entstehen. Die hier in einer Kurzfassung vorliegende Dissertation führt neue Methoden zur interaktiven Darstellung von Volumendaten auf universeller Hardware ein. Diese Methoden nutzen die in handelsüblich...

Soft ferromagnetic Fe-based bulk metallic glass key-shaped specimens with a maximum and minimum width of 25.4 and 5 mm, respectively, were successfully produced using a high pressure die casting (HPDC) method, The influence of die material, alloy temperature and flow rate on the microstructure, thermal stability and soft ferromagnetic properties has been studied. The results suggest that a stee...

Since zinc die casting’s conception over 100 years ago, many new and improved developments have taken place to progress the industry and offer component designers a costeffective alternative to higher priced alloys and processes. The zinc industry has continued to develop new alloys in response to some of the challenges that face it. One such development is EZACTM, Eastern Alloys’ high strength...

BACKGROUND Conventional investing and casting techniques are time-consuming and usually requires 2-4 h for completion. Accelerated nonstandard, casting techniques have been reported to achieve similar quality results in significantly less time, namely, in 30-40 min. During casting, it is essential to achieve compensation for the shrinkage of solidifying alloy by investment expansion. The metal ...
