As fun as it is to highlight our casting services, processes, and toolmaking capabilities, that is not what today&#;s post concerns. As the title no doubt gave away, we will be discussing the history of castings in today&#;s post. So whether you are interested in educating yourself about metal castings for your genuine pursuit of knowledge or you are interested in finding a machine shop in Denver worth their salt, keep reading! This post is for you.
Before we talk about the history of something, it would probably be helpful to inform our readers what exactly the manufacturing process known as casting actually is. Casting is a process which involves taking a liquid material being poured into a mold of some sort. In this mold is a cavity of whatever eventual shape of the product will be. Once the liquid material cools, it will solidify into a part called a casting. Epoxy, plaster, concrete, and clay are all examples of cold setting casting materials that are cured after two components are blended. However, we at Protcast Inc. deal with metal castings. And in metalworking, the metal will be heated until it turns into a liquid, whereupon it&#;s poured into a given mold. Metal casting molds include runners and risers which allow the metal to fill up the mold. While any kind of metal can be cast, the most commonly used metals include steel, aluminum, copper-based alloys, and iron. Castings can vary in weight in a fairly significant way &#; from less than an ounce to an individual part weighing over 100 tons!
For the record, if you have a project of that magnitude you&#;d like us to complete, it might take more than a few days, just so everyone is aware!
Before we talk about the earliest castings on record, we&#;d be remiss if we failed to mention the mythology behind casting in the first place. Throughout prehistoric times, ancient legends of the gods of the foundry and volcanoes, Hephaestus and Vulcan, were deities who made thunder crack for the very first time and shaping novel weapons with hammers for their cohorts. Humans were said to have stolen fire from these gods, for obvious reasons, one of them being so we could create our own foundry, which can be described being anywhere that a metal workshop could be found. In these foundries, humans made metal soft and malleable, which allowed mankind to turn base metals into bronze and other useful casts.

Speaking more factually on the matter, the Fertile Crescent, the region between the Tigris and Euphrates Rivers that is also called Mesopotamia (modern-day Iraq), is where the furnace and foundry got their beginnings. Starting with clay casts made from hot fire pits used to help shape copper, silver, and gold, the casting methods became more advanced over time. While early castings typically involved copper to make more sophisticated casts, a breakthrough occurred when these early metalworkers started using tin. Tin had the unique effect of reducing the temperature at which two different metals could be melted together to form bronze &#; which happens to be the first alloy ever made by humans.
As the centuries past, many people groups began to settle down in permanent locations, forgoing the nomad culture of their ancestors. This newfound permanence led to the capacity for smiths to improve their craft from generation to generation, along with an improved dedication to the craft of mining. This is when the founding industry got its proper beginnings, as blacksmith shops opened in cities and towns. These smiths, using manually operated bellows and pipes that you&#;ve probably seen in the movies, behooved many industries beyond that of warfare, as farmers were able to utilize inventive instruments to improve the efficiency and quality of their work.
Now that we&#;ve covered the early beginnings of casting and foundries, we will offer up a timeline of significant breakthroughs concerning metal casting and its advancements.
As it turns out, we will need to split this topic into a two-part series, seeing as how we weren&#;t able to get past the 18th century! That being said, keep an eye out for part two, in which we&#;ll highlight the significant metalworking events of the 19th and 20th centuries.
