Aluminum Casting is a process of combining metal and melting the alloy in a furnace to form the desired shape. The most commonly used types of this method include extrusion molding, rotary molding, and press casting. All three processes require high levels of precision machining to create the right dimensions. This results in higher production costs but also makes it possible for fewer workers to participate in the production run. Aluminum casting is typically used in automobile fabrication due to its lightweight properties. However, automakers are more interested in aluminum’s excellent durability, superior corrosion resistance, and improved maintenance. According to the Organisation Internationale des Constructeurs d'Automobiles (OICA), total vehicle (commercial + passenger) sales reached 96 million units in 2017, increasing from 86 million units in 2013 globally. According to the India Brand Equity Foundation (IBEF), India’s domestic automobile sales reached 21.55 million units in FY20, registering a CAGR of 1.29%. Such high demand for automobiles can stimulate growth of the aluminum casting market.
Recently, in February 2021, Vedanta Limited launched aluminum cylinder head alloy for cylinder heads and other automotive components
Aluminum Casting is done through two different methods - extrusion mold casting and pressure die casting. Exprusion mold casting is the first common type of casting used today. It involves creating a mold from a solid piece of aluminum and pouring the melted material into the mold. After it cools, the result is a cast part that is both sturdy and strong. Emerging economies have witnessed robust industrialization over the years. This has prompted the demand for aluminum casting in various end-use sectors. Aluminum Casting can be separated into two categories based on the process required for forming the metal. Rotary and extrusion molding are the two main types. In the former process, molten metal is directed to the mold at a very high speed. This creates the needed hot spots and results in the most accurate and consistent results. This type of casting produces shapes with high tolerance to heat. However, aluminum casting has witnessed a slight decline in adoption due to increasing preference for aluminum alloys with magnesium.

Emerging economies from Asia Pacific have emerged as primary consumers of aluminum casting. This is typically due to automakers across the globe shifting their production facilities in these countries, owing to the availability of cheap labor.
