Metal casting is the process of pouring liquid metal into a mold, which then hardens into the shape desired. This method is used commonly in the industry like dawangcasting.com to cast car parts, engine blocks, cannons, turbine blades, and many other things. However, this process can also be done at home with very little equipment; one only needs two chunks of scrap metal (one stronger than the other), sand or coal for making a mold, something to make a hole in the sand/coal (a drill will do), and some sort of crucible. The result will be an exact replica of whatever you pour molten metal into to create your mold.
Note that this practice should only be done outside to avoid breathing toxic fumes created by burning coal or wood. Also, be careful not to burn yourself while making the mold.
Advantages of Metal Casting
- With some simple equipment, you can create your own metal objects at home.
- Since it uses no molds, you can create any shape desired.
Disadvantages of Metal Casting
The process is very time-consuming and labor-intensive. This limits the number of things that one person can produce with a given setup to a few items a day. If a larger production rate is required, more advanced equipment will be needed, which greatly increases the cost of startup materials as well as the risk of injury from using them. In addition, there are safety concerns associated with molten metal – if precautions aren’t taken properly, serious injuries could occur from spilling or splashing molten metal on yourself or nearby people/objects
