Aluminum die casts are popular in many industries due to their impeccable properties such as tensile strength, durability, and lightweight. However, there can be a need for some enhancement of these properties for specific applications, whether aesthetics or function-related. To improve these properties, aluminum casting finishing is essential.

There are many finishing options used in aluminum die casting. However, choosing any should depend on the proper understanding of the effects on aluminum, the efficiency and productivity, and how it adds to the aluminum die casting cost. This article will discuss the different surface finishing you can use for an aluminum die-cast part.

General Steps of Aluminum Die Casting Finish Process

Stage #1: Deburring

After casting the aluminum product, the die cast undergoes deburring to remove unwanted sharp edges, burrs, flash, and debris. At the end of this stage, you should have a smooth and bright surface

Stage #2: Conversion Function Coating

After deburring the aluminum die cast, a conversion coating is applied. This helps remove remaining oil, agents, and other contaminants that can affect the quality of the surface finishes. Aside from preparing the product for the surface finish, it can also be a pre-step for certain surface finishing options such as painting. You can also use it as a final finish.

Stage #3: Final Surface Finishing

Use several surface finishing options to improve the die-cast product’s durability, corrosion and heat resistance, surface performance, and insulation. Each surface finishing option has advantages and should be properly analyzed before selection.

Aluminum die casts have inherent properties such as high strength-to-weight ratio, durability, corrosion resistance, and lightweight. Consequently, they are an important part of several industries. With cast aluminum finishes, it is possible to enhance these properties making the material functionally and aesthetically appealing.
