Metalcasting, in a simple summary, is where manufacturers pour liquid metal into molds and then let it harden over a period of time into a certain shape. Notably, this is just the first part of the process and there are several more steps to it. This process is very versatile and it can be used for so many different procedures. Because this procedure can be used in so many different fields, this field requires a lot of technical education.
The molds that are used for liquid metal have to be able to withstand very high temperatures, so there are certain materials that are more preferred, such as limestone, ceramic and wood. In order to achieve exactly the right design, these molds are usually shaped with either sand, clay or wax. In order to use some of these pieces as individual units, some of the molds snap together to create matching ends.
The foundries where these metals are melted also allow for other metals to be mixed in depending on the desired result for the end product. As more alloys are mixed in, it’s important that the operators are skilled because the level of knowledge that is required increases.
Once the metal has hardened into the preferred shape, then the product must be finished through the process of grinding, sanding and polishing. Each material that is mixed will require its own amount of grinding and this is something that must be determined by the manufacturer.
Some projects in this field might e small enough to be completed at home with a personal foundry setup. If this is the case, then the person operating it needs to be very careful so they don’t cause an accidental fire. The first thing you should do before putting any information to use that you find online is to read through the safety precautions at least a few times, in order to prevent accidents or injuries.
You can get some better education on this when you watch videos online as people go through the process and you can learn to do it without injury. In terms of learning on your own, check out the American Foundry Society to see what resources they offer and how you can learn from them as an individual.
The many fields that these items are used in are so various, and for the individual who wants to get involved, there is a lot of opportunity for occupational growth. This post may show you the very beginnings of the process in terms of metalcasting, but there is much more to it if you decide that it’s your choice of a career. This is a field that has been around for decades and will continue to be.
