Die Casting Die casting is an all-around process for producing engineered metal parts by forcing molten metal under high pressure into reusable steel molds. These molds are called dies. These can be designed to produce complex shapes with a high degree of accuracy. THUS it is obvious that size of the mold needs to be precisely developed. Parts can be sharply defined with smooth or textured surface and these are suitable for a wide variety of attractive and serviceable finishes. Without being aware of the nitty-gritty of die casting process a common man continues to use a number of items in day to day life. Metal industries are highly governed by the research and development in the die casting both design and execution. Die casting is used for the highest volume, mass- produced items manufactured by the metal working industry and they can be found in thousands of consumer, commercial and industrial products. The earliest examples of die casting by pressure injection as opposed to casting by gravity pressure occurred in the mid 1800. In 1849 Sturges – a patent was awarded for the first manually operated machine for casting printing type. This process was limited for printer’s type for 20 years. But development for other shapes began to increase. By the year 1892 commercial applications include parts for phonographs and cash registers were come. But in the year of 1900 mass production of many parts began. The first die casting was of various compositions of tin and lead but as soon as zinc and aluminium introduced in 1914 the use of lead and tin was declined. By the year 1930 Magnesium and copper quickly followed. The metals and alloys used for die casting are many such as copper, cast iron, ductile iron, etc. With slight variations in the composition of these constituent metals the desired results in the properties of the product can be achieved. Thus there are tremendous opportunities in the field of die casting and the scope of the die casting industry is increasing very fast. There are many affiliated businesses which continue to earn benefits of the growth of this industry. There are so many advantages of die casting. Die casting is an efficient, economical process that offers range of shapes and components than any other manufacturing technique. Parts have long services life and may be designed to complement the visual appeal of the surrounding part. Designers can gain a number of advantages and benefits by specifying die cast parts.
