The Intricacies of Making Metal Products
Investment casting is an old process. I’m not talking old like, two hundred years old, but old like, five millennia old. With five thousand years of development, investment casting companies have a pretty good handle on how to create large amounts of pieces of metal equipment that are consistently uniform in size and shape. It’s a fascinating process that begins with the design of the equipment you’d like to make, then you make a wax mold, add a little fire, and next thing you know, you’re casting! Okay, so it may not be that simple.
Casting has taken on a variety of different forms throughout the development of modern technologies. Where all casting was originally done with wax molds, today we see methods like die casting, sand casting, and lost foam casting. Wax molds are still employed in investment casting today, and some people prefer investment casting to something like die casting because you’re able to form more intricate designs or types of metal equipment with the former than you are the latter. One of the only drawbacks to choosing investment casting over sand or die casting is that it is not as cost effective as those two processes. So depending on the kind of metal parts you’re looking to make, the casting procedure you require may vary.
Investment casting is used in many industries, but because it functions so well in making intricate metal designs, it is very prevalently used in the manufacturing of firearms. Though a more expensive form of casting metals like aluminum, copper, and steel, the intricacy required for making a gun calls for investment casting. This isn’t to say that any piece of metal you’re casting doesn’t hold its own level of importance, but when you’re dealing with something like a firearm the stakes are a little higher in ensuring proper functioning of the finished product. And thanks to investment casting you can create metal works that are both functional and beautiful.
