Aluminum parts undergo anodizing and sandblasting treatment is a composite surface finishing technology, specifically designed for high-end products that pursue outstanding texture and long-lasting performance. This process first conducts precise sandblasting on the aluminum parts processed by CNC, using a medium of specific particle size (such as glass beads or alumina sand) to form a uniform and fine matte texture on their surface. Subsequently, on this basis, standard Type II or enhanced Type III hard anodizing is carried out.
This process creates a surface with multiple advantages: the matte texture effectively eliminates glare, hides fingerprints and fine scratches; The oxide film layer provides the textured surface with the same excellent hardness, wear resistance and corrosion protection as the smooth surface. The final part not only features a warm and soft high-end touch and visual performance, but also ensures long-term durability in frequent usage environments. This process is widely applied in fields such as high-end consumer electronics casings, professional-grade tool handles, precision instrument panels, automotive interior parts, and medical equipment, where both sensory experience and reliability are strictly required.
FAQ
Q1: Will Aluminum parts undergo anodizing and sandblasting treatment damage the precision or strength of aluminum parts?
A: Sandblasting is carried out under controlled parameters and is a surface pretreatment process that will not affect the structural strength of the parts or the dimensional accuracy of the main body. We use automated equipment to precisely control pressure, distance and Angle, ensuring uniform texture and minimal material removal (usually at the micrometer level), and compensating for this in subsequent process design.
Q2: Can a sandblasted matte surface be treated with colored anodizing?
A: Of course. The textured surface after sandblasting can also be dyed and anodized. A matte base makes the color presentation softer, more reserved and more textured, avoiding the flamboyance of glossy colors. Classic matte black, deep space gray, military green and other colors perform particularly well on such surfaces.
Q3: Is the wear resistance of the sandblasted and oxidized surface worse than that of the bright oxidized surface?
A: In terms of the intrinsic hardness of the oxide film, there is no difference between the two. Wear resistance mainly depends on the thickness, Type (Type II or Type III) of the oxide film and the sealing quality. Matte textures may be more likely to contain hard particles at the microscopic level, but in conventional wear tests (such as Taber wear resistance), their performance is comparable to that of bright oxidized surfaces of the same grade. For extreme wear scenarios, we recommend using matte hard anodizing.
Q4: How can the consistency of sandblasting texture be ensured during large-scale production?
A: We ensure consistency through standardized operations: 1) Fixing the model and particle size of the sandblasting medium; 2) Digital setting and locking of equipment parameters; 3) Regularly update the medium to maintain sharpness; 4) Use standard samples to compare and confirm the first piece of each batch. Customers can pre-confirm the texture sample blocks as the acceptance criteria for mass production.
Q5: Can a contrast effect of partial brightness and partial matte finish be achieved on a single part?
A: Yes, but this belongs to the selective sandblasting mask oxidation process, which has relatively high technical requirements and costs. Before sandblasting, the bright areas that do not require treatment need to be precisely covered and protected. After completion, they should be removed and then undergo overall anodizing. This can create a unique visual and tactile contrast and is suitable for high-end designs.
