The local surface compactness is not good, and the partial peeling is caused by the failure of the compact layer under the action of external force due to insufficient surface compactness or poor meshing of the local die casting.

Metal parts with messy shapes, clear outlines, thin-walled deep cavities can be made.

The casting should be designed to strictly control the smelting process, speed up the smelting speed, reduce oxidation, and completely remove slag inclusions.

Before coating the aluminum castings, prepare the surface quality of the metal material wall, which is the key to the adhesion of the architectural coating.

Among the cast alloys, cast aluminum alloys are the most widely used, and other alloys cannot compare.

The whole process of the application of aluminum castings in production is to deal with many other castings with unparalleled advantages.
