Products Description
Our CNC machining aluminum sand blast anodized shell represent the pinnacle of metal enclosure manufacturing. Crafted from high-grade 6061 aluminum alloy, they are precision CNC machined and then uniformly sandblasted to achieve a fine, consistent matte finish. Finally, anodizing creates a hard, wear-resistant, corrosion-resistant, and colorable surface oxide layer. Not only does this provide robust physical protection and high electromagnetic shielding effectiveness for the precision components within, but its exceptional tactility, elegant appearance, and exceptional durability make it an ideal choice for high-end consumer electronics, professional industrial equipment, and medical devices, serving as a key component in showcasing product quality and brand value.
Product Process
1
Milling, drilling, and tapping are performed from solid aluminum billets using multi-axis CNC machines. This process ensures extremely high precision in housing dimensions, complex internal features, and excellent overall structural integrity. Tight tolerances (typically ±0.05mm or better) ensure a perfect fit with internal components.
2
After CNC machining, the shell surface is sandblasted using a media with a specific particle size (such as aluminum oxide or glass beads) under controlled pressure. This step eliminates CNC machining marks and creates a uniform, non-directional matte texture. This provides an optimal adhesion base for subsequent anodizing and significantly improves tactile feel.
3
This is an electrochemical process in which the aluminum shell is placed in an acidic electrolyte, acting as the anode. A voltage is applied to the surface, creating a dense layer of aluminum oxide (Al₂O₃). This oxide layer possesses extremely high surface hardness (reaching Mohs' hardness of 8 or higher), excellent wear and corrosion resistance, and its porous structure absorbs dyes, resulting in rich, long-lasting color.
Materials involved
This CNC machining aluminum sand blast anodized shell is made of 6061 aluminum alloy and is formed by CNC milling. The aluminum alloy casing can be used in communication and electronic equipment. The advantages of the aluminum alloy casing are its lightweight and excellent thermal conductivity. The thermal conductivity of aluminum is three times that of iron, making it suitable for heat dissipation components. It can effectively control the internal temperature of the equipment and extend its service life. High strength and rigidity, with the tensile strength of some models reaching over 430MPa, meeting the requirements of high pressure resistance. It is also corrosion-resistant, easy to process, and has a low cost. The surface can be treated with anodizing or spraying according to customer requirements. We can customize different integrated, split, protective and waterproof aluminum alloy shells for customers, which are widely used in digital communication, environmental monitoring, instrumentation and outdoor electronic industry products.
