In today’s world a casting production without any defect is almost impossible. After the application of various optimization techniques and process we still are not able to get the defect free castings. So it is critically important to analyze the root cause of casting defect with in the process itself, so that any changes which can hamper the defect intensity can be invoked at the time of manu...

Nowadays, fuel consumption and carbon dioxide emissions are two of the main focal points in vehicle design, promoting the reduction in the weight of vehicles by using lighter materials. The aim of the work is to evaluate the influence of different aluminium foams and injection parameters in order to obtain compound castings with a compromise between the obtained properties and weight by high-pr...

The great attention toward environmental issues and especially on energy utilization, leads the European Union to implement the 2009/28/EC Directive, fixing three main goals to be achieved for 2020 by the EU member states: 20% reduction of the greenhouse gases emission, 20% increase of using renewable energy and 20% improving of energy efficiency. To achieve these objectives, new environmental ...

In this research experiment computational fluid dynamic (CFD) models were constructed, within Ansys Fluent TM v.R1, to investigate phenomena occurring during the Vertically Upwards Continuous Casting (VUCC) of 8 mm diameter, oxygen free copper (OFCu) for alterations casting speed. The simulated influence heat transported over a 0.1 air gap formed die was investigated and value wall transfer coe...

In diesem Beitrag wird eine Methode zur computergestützten Optimierung einer Kraniotomieöffnung bei der kurativen Behandlung von subduralen Hämatomen vorgestellt. Lage und Form der Öffnung werden mittels GPU-beschleunigter genetischer Algorithmen bestimmt und anschließend visualisiert. Im Vergleich zur manuellen Spezifikation kann eine Verkleinerung der Schädelöffnung bei gleichzeitiger Erhöhun...

The paper presents the method of preparing a composite slurry composed of AlSi11 alloy matrix and 10 vol.% of SiC particles, as well as the method of its high-pressure die casting and the measurement results concerning the tensile strength, the yield point, the elongation and hardness of the obtained composite. Composite castings were produced at various values of the piston velocity in the sec...

As the competition in market is growing at a very fast pace, one can survive in today’s industrial world by adopting the philosophy of Lean Manufacturing. In order to stay competitive, producing cheaper products at a faster rate Lean Manufacturing would help the industry. This paper represents a case study of Die casting industry. This case study is used to illustrate the steps in implementatio...
