What is the grip?

Pressing casting is a method of forming metal into shapes using two countries that are pressed together. Most cast techniques use two die, which are pressed together before the metal is added, but when the casting is pressed, both are pushed together after the metal is added. This is done with liquid metal and the upper matrix is ​​only removed when the metal cools. Using this technique, the metal will usually be stronger, with better grains and less metal reduction. This is commonly done with magnesium, aluminum and their alloys, but many other metals can be used.

Most casting techniques include the use of two dies, but pressing casting uses the ground both lits are usually placed together and the liquid metal is poured into the housing. As the casting is pressed, the flow of liquid metal is placed in the lower death and the upper matrix comes and the metal presses into the shape. The pressure exerts through the upper matrix, so it is not a strict cast, as the fittings to create a hybrid technique.

In this application you can only use the flowthat metal. While materials such as plastic can melt at high temperatures, this technique will not be suitable for drilling plastic. After setting the upper matrix, the workers wait for the metal to be completely cool. As soon as it is cool, the upper matrix will be released and the desired shape will be thrown into the now solid metal.

There are several advantages that press casting that increases the functionality of metal. One of the advantages is that the metal will usually be stronger because the cooling method is a better grain compared to other techniques of casting. There is a tight seal and pressure between the two dies, so less metal can evaporate, leading to less reduction during the cooling process.

Magnesium, aluminum and metals alloyed by these two sources are usually used when casting is pressed, so it melts and have a variety of uses. At the same time, almost any metal can be used in this process. If metal is not a liquid at room temperature-such as mercury or dangerously radioactive- as plutonium- most metals with low to medium temperature can be used. Metals with a high melting temperature are often unusable because they would eventually melt or are too difficult to occupy them properly without deformation or other errors.
