Recent developments in Computer Aided Design (CAD) have drastically reduced overall design cycle time and cost. In this paper, wirePATH, a new method for rapid direct tooling, is presented. By using specialized interactive segmentation computer software and wire electrical discharge machining (wire EDM), wirePATH can reduce manufacturing time and cost for injection molds, casting patterns, and ...

The ASTM F-75 (Co-28%Cr-6%Mo) is widely used as a biocompatible alloy in medicine for manufacturing implants. In this study, effect of mold preheating on the as-cast microstructure of the alloy was investigated using the solid investment casting process. Several mold preheating temperatures of 550, 700, 850 and 1000 °C were selected at the same melt superheat. The samples were characterized by ...

The article presents pr ocess application of the rapi d prototyping (RP) for manufacturing of blades of aircraft turbine in monocrystallization and also directional crystallization of casting process. It is describing the method of modelling of the chosen elements of casting model kit with the usage of RP and RT system s. The article presents the analysis of additive rapid prototyping methods (...

In the current study, a three-dimensional measurement of magnetic flux density was performed for 280 mm width × 250 thickness continuous casting bloom mold installed with electromagnetic stirring varied intensity and frequency. The increased gradually to peak value then decreased along downward vertical direction, it in transverse direction from copper plate center mold. field stirrer calculate...

In die casting, laminations are a serious problem because they cause blisters, stripping defects and zinc deposition on the mold surface. Blisters reduce quality of product, deposits surface productivity. Therefore, analytical prediction risk lamination formation optimization gating system for reducing occurrence due to very important before designing mold. To optimize system, we used an evalua...

Ductile Cast Iron is a widely used cast iron. iron applications are in various sectors of modern mechanical industries. has wide uses the field car industry, military industries, agricultural equipment, construction and mines. The production ductile faces many technical difficulties our local factories due to difficulty providing equipment technologies for its by common methods. In this study, ...

A particle-capture model based on local force balances has been developed, implemented into computational models of turbulent fluid flow and particle transport, and applied to simulate the entrapment of slag inclusions and bubbles during the continuous casting of steel slabs. Turbulent flow of molten steel is computed in the nozzle and mold using transient computational fluid flow models, both ...
