Investment Casting is the manufacturing process which is used to make desired parts(castings) using a wax pattern coated with ceramic refractory material. Once the wax mold is coated with ceramic coating and slurry a shell ...

Aluminum alloys are the most widely used alloys in the current era. Their applications range from high speed air crafts to domestic utensils. These are light weight but they are not as strong as steel. Many processes are ...

Friction Stir Welding is a welding technique invented in last part of twentieth century in which a high speed rotating tool traverses through the two base materials to be welded in solid state below melting temperature. ...

Supply chain management (SCM) includes the management of the movement and storage of goods and services from their point of origin to the point of consumption. A Supply Chain Network (SCN) is an evolution of the basic ...

This study is carried to find the thermal hydraulic efficiency of smooth twisted elliptical tubes and enhanced twisted elliptical tubes which has fins at both axes e.g. Major axis and the Mi-nor Axis of elliptical cross ...

In various engineering applications, need of miniature components is increasing manifolds with the continuous evolution of micro and nano technology. There are several techniques with in the subtractive and additive ...

Energy harvesting considered to be the ultimate source for long term power supply. Extracting energy from vibration produced in a piezoelectric film gain most attention over a period due to its ability to directly converting ...

3D printing is one of “Additive Manufacturing” technique that has been defined as “the process of joining materials to make parts from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing and ...

The performance and durability of components in engine valve train is largely governed by the friction. The valve train is often subjected to severe and transient operating conditions promoting friction, greatly. The aim ...

Investment casting is a manufacturing process in which a wax pattern is coated with a refractory ceramic material. Once the ceramic material is hardened its internal geometry takes the shape of the casting. Optimization ...
