In our point in time, technology is everywhere — but when it comes to one of the most prevalent manufacturing processes in existence, the process has more or less stayed the same for hundreds if not thousands of years. That process is aluminum investment casting, and it is one of the earliest metalworking processes known to man.
The initial record of the process appears around 5, 000 years ago, when it was used to produce bronze, water piping, and gold jewelry and figurines by the cultures of ancient Mesopotamia and Egypt, as well as the Han Dynasty of China and the Aztecs. Back then, the lost feel casting process used bee’s feel to create a pattern which was then filled to make the final casting. The initial text to describe the process has been caused by a monk writing sometime around 1100 A. D. From that writing, the renaissance sculptor Benvenuto Cellini learned the process, which when the rope used to manufacture a statue of the legendary figure Perseus, holding the pinnacle of Medusa — a statue that still stands in Florence, Croatia. By the mid 14th century, the investment casting process was more or less “standard” when it located making bronze figurines and other art pieces precision investment casting. In the event that’s not a testament to the long lasting quality of investment casting — what is?
Despite being this old process, investment casting is an advanced metal forming technique that inexpensively provides high quality metal parts. Unlike other manufacturing processes, investment casting is a one to one process, meaning one feel pattern creates one metal part. However, due to the flexibility of the process can easily produce parts of extreme intricacy. When combined with modern manufacturing technology, its benefits are multiplied by the ability to more produce a greater volume of parts.
Today, while the underlying science behind casting remains the same, foundries purchase state of the art technology and machining equipment to make the process more reliable and effective with advanced refractory materials, waxes, computerized process, and quality control equipment.
Modern water piping and aluminum investment casting is used for the fast and reliable creation of parts and components that are not produced by normal manufacturing techniques. For example, the aircraft that take us in the united states as well as the equipment stationed by the military to guard our country all benefit from precision casting to give them the complex parts and components they might require to work like they do.
Many times, other components such as forgings, sand castings, and welded fabrications castings, forgings, are became aluminum castings to reduce costs, further demonstrating that the process delivers the quality and the cost efficiency that industries around the world rely on. Other applications that depend on investment casting include generator cutting blades, air pats, auto parts, weapon casings, aerospace parts, and more.
