Aluminum is one of the most commonly used metals in aluminum castings. It is lightweight, but very research, allowing it to run in many different applications. Although there is a problem of shrinkage and cracking when the aluminum castings are cured, the best results can be achieved in accordance with the specific guidance made by the industry.

It is not difficult to shoot, but it does take a lot of steps to show it correctly. The first step is to determine the exact geometry of the mold so that it has the correct shape. For the basic mold, the casting consists of two parts, and then connected together. When the metal is poured into the mold, it will fill all the negative spaces and, when cured, the manufacturer has the exact molds required.

Now die making, the next step is to prepare the metal. Metal is naturally solid. However, in order to shape it into a mold, it is necessary to melt it into a liquid. This requires heating it to a very high temperature. Once it is liquid, it is poured into a small opening in a mold, often referred to as a door or riser. Since the metal may have a rough edge, the margin is added to make it smooth.

Remove the mold and then send the casting to any desired manufacturing. However, normally, it is smoothed and polished to ensure that the mold meets the exact specifications required by the manufacturer.

Another problem is its high shrinkage in the 2-8% range. This means that the final casting is 2-8% smaller than the original product, which is not what the manufacturer wants. Therefore, shrinkage should be considered in the manufacture of molds.

In addition, aluminum is the great metal for making castings, which is why so many companies rely on it. Because of its great use, it is the manufacturer's most common metal for making molds.
