Defects and strength of aluminum alloy die casting parts.

Study of Process Parameters of Gravity Die Casting Defects

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...

Aluminum and Aluminum Alloys Casting Problems

Aluminum castings have played an integral role in the growth of the aluminum industry since its inception in the late 19th century. The first commercial aluminum products were castings, such as cooking utensils and decorative parts, which exploited the novelty and utility of the new metal. Those early applications rapidly expanded to address the requirements of a wide range of engineering speci...

Tribological and Wear Performance of Nanocomposite PVD Hard Coatings Deposited on Aluminum Die Casting Tool

In the aluminum die casting process, erosion, corrosion, soldering, and die sticking have a significant influence on tool life and product quality. A number of coatings such as TiN, CrN, and (Cr,Al)N deposited by physical vapor deposition (PVD) have been employed to act as protective coatings due to their high hardness and chemical stability. In this study, the wear performance of two nanocompo...

The development of surface engineered coating systems for aluminum pressure die casting dies: towards a ‘smart’ die coating

A Study for Analyzing Effects of Design Parameters in the Sand Casting Process of Aluminum Alloy

The use of aluminum alloys are of significant use in industry. Studying of design parameters of such products is important as not much work has been done for optimizing it. The generic formulation involves the flow, velocity, continuity fluid dynamics and shape related issues. The time for filling the mould and shape factor also play major role in performance of the casting process. In this pap...
