Advantages and disadvantages of die casting

Metal die casting – is a production technology of castings, in which the alloy under pressure up to 700 MPa quickly fills the mold. Products made in this way can be of different sizes and have weigh up to several kilograms. As a basic raw material normally are used following: non-ferrous metals — copper, aluminum, and their alloys.

Die casting makes it possible to obtain high-precision products (along with such technology as powder metallurgy, which allows to obtain sintered metal parts that are particularly hard and wear-resistant).

Our company offers the manufacture of parts for LED lighting and other high quality castings. One of the main advantages of die casting is the resistance of finished products to corrosion. The fact is that in the process of their manufacture a strong surface crust is formed, which has a high density and low moisture permeability.

Die casting is quite fast, although this process takes place in several operations, including the preparation of the mold, the melting of raw materials, the pouring and pressing of the melt, and so on. The resulting castings do not require subsequent machining (the surface of the product has low roughness).

When using the die casting technology is possible to use multi-place forms. In addition, this technology allows the manufacture of parts with rather thin walls, such as carburetor diffusers. This method produces castings with embossed, clear contours, the accuracy class of which corresponds to 3-7.

The main disadvantage of die casting is the fact that in the process of pouring the melt, the formation of vortices is possible, leading to the ingress of air into it. But this process is subject to careful control by our specialists and is practically reduced to zero.
