Aluminum alloy casting part- shot blasting refers to the process of removing riser and heat treatment after aluminum alloy blanking is completed (generally, the part needs heat treatment to increase the relevant mechanical properties), and a process before machining or other surface coating, This process is indispensable because

1. After shot blassting, surface strengthen could be increased.
2. Casting surface is getting smoothy.
3. Clear burrs and other convex objects & other surface defects.

Shot blasting is carried out on the surface of casting with specific nearly round steel balls, and there is a corresponding shot blasting equipment to do it.



Passivation refers to a process in which a metal is oxidized by a strong oxidizing agent or electrochemically, and the surface is made into an inactive state, that is, a passive state, which is a method of converting a metal surface into a state and not easily oxidized, and delaying the corrosion rate of the metal. In addition, an active metal or alloy in which the chemical activity is greatly reduced and becomes a noble metal state is also called passivation.


Power Coating


Aluminum alloy casting part with power coating surface has strong adhesion, is not easy to burn, can protect metal surface long time. Compared with ordinary surface treatment, painitng, the advantages are reflected in advanced technology, energy saving and high efficiency, safety and reliability, and bright color. Therefore, it is often used in the field of light industry and home decoration. Of course, casting aluminum alloy is one of the many applications in these aspects, so it is very common to spray the aluminum alloy castings, like decoration, shading part, furniture part, cookware part, hardware, etc.


After aluminum alloy is oxidized, a protective film is formed on the surface.

Aluminum is a very active metal, which naturally produces oxidation in the air. An oxide film is formed on the surface. The main component of the oxide film is aluminum oxide. This oxide film has strong corrosion resistance and can be protected. Aluminum parts will not continue to oxidation.

The thickness of oxide film naturally formed by aluminum in the air is very thin and it is easy to corrode in use. In order to solve this problem, most industry aluminum parts use a special method to form an artificial oxide film. This process is called anodization.

A dense high-quality aluminum oxide film is formed on the surface, which can greatly improve the protection of aluminum parts and improve alu casting parts’ aesthetics.
The thickness of the oxide film formed by anodization is several micrometers to several hundred micrometers, and anodization does not affect the surface quality of aluminum parts.

Anodized film has high hardness and wear resistance, strong adhesion, strong adsorption capacity, good corrosion resistance and electrical insulation, and high thermal insulation. Due to these specific properties, it has been widely used in various aspects.
