In its most basic summary, metalcasting is defined as liquid metal being poured into a mold and then being allowed to harden in that shape. There are more steps to it, of course, but this is the beginning of the process. It’s especially helpful because this particular procedure is extremely versatile and it can be used for a variety of needs. It’s also a skill that requires a lot of technical education because it can be used is so many different fields.
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. Normally, wax, sand or clay is used to shape these materials, so the end result is the right design. In order to make sure that the pieces can be put together when the work is done, some of these molds are made to snap together.
Based on the needs for the end product, the foundries where the metals are melted create a place for particular metals to be mixed, so the desired end result can be achieved. As more alloys are mixed in, it’s important that the operators are skilled because the level of knowledge that is required increases.
In order to create a professionally finished appearance, these items must be ground down, sanded and polished before they can be considered complete. Since each product is created differently with various materials, the manufacturer will need to determine how much grinding is required for each finished product.
Some projects in this field might e small enough to be completed at home with a personal foundry setup. If someone is going to pursue this on a small setup system like this, caution should be taken so that accidental fires don’t get started. 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. You can get a ton of great information from the American Foundry Society if you contact them and see what resources they offer.
This field gives an individual a lot of opportunity to create products that are used in so many areas and you can learn as much as you wish to pursue. 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. In terms of potential, this field has been around for a very long time and won’t go away any time soon.
