Aluminum die casting plays a crucial role in the growth of the global aluminum industry. It has expanded in its application ever since and is now being used across a wide range of products.
It is possible to carry out aluminum die casting by using custom metal casting. The castings for aluminum are based more on the requirements and design considerations of the customers. For die casting process, most of the aluminum foundries choose 2D drawings with the exception of complex castings that require 3D drawings. Moreover, the presentation of the samples by the customers is immensely useful for aluminum foundries since it aids them in resolving any technical issues that arise during the process.
The process of melting is entirely different for both aluminum and alloys. However, just like most other casting processes, aluminum die casting is also prone to numerous defects. These are dependent mostly on the channel and the coreless induction furnace used in the process.
Defects
The various defects that occur in aluminum die casting are attributed to many factors such as the choice of the furnace – whether fuel oil, natural gas, electric radiation, and resistance powers it. Besides that, the degradation can also affect the melting and casting processes in different ways.
The wrong setting of the temperature and time can cause increased hydrogen absorption, which will severely affect the composition. This will also lead to the loss of oxidation along with the formation of complex oxides.
Inappropriate setting up of the temperature and time will also result in high reactivity and low vapor pressures. This will significantly affect the mechanical properties of aluminum die casting.
Solutions
One of the best ways to avoid such defects is by relying on good die casting companies and aluminum foundries. Moreover, providing the foundries with all the requirements along with detailed drawings can also help to prevent defects in aluminum die casting. This includes the technical requirements of the product such as weight, texture, dimensions of the rough castings, surface coating, hardness and strength of the material, as well as heat treatment.
You also need to have good knowledge regarding the various factors that affect the changes in the pricing of the aluminum die casting process. Proper consideration of such key die casting requirements can prevent many of the defects associated with the process.
