FAQ's
1. What is Anodizing used for?
Anodizing is a process that forms an aluminum oxide layer on the surface of an aluminum alloy,
significantly enhancing its wear resistance due to the hardness of aluminum oxide.
Anodized aluminum finds applications in scenarios where wear resistance is crucial, such as
components constantly in motion and in contact with other materials. Common applications include
coupling bodies, stop flanges, and valves.
Dyeing is another popular application of anodized aluminum. The porous nature of the aluminum
oxide layer created during anodization allows certain dyes to be absorbed, enabling the customization
of colors for aluminum alloys.
This opens up possibilities for dyeing anodized aluminum in products like knobs and body housings.
Furthermore, aluminum oxide, being less conductive than aluminum, can serve as electrical insulation.
This feature finds utility in applications like electric car battery terminals and cable pins, where
electrical isolation is essential.
2. Post-processing and surface finishes for CNC machining
CNC-machined parts as they emerge from the machine often exhibit visible tool marks, a feature that
may not align with your specific part requirements.
Fortunately, there exists a multitude of post-processing techniques aimed at enhancing the surface
appearance and elevating attributes such as wear resistance, corrosion resistance, and chemical
resistance.
Methods like anodizing, bead blasting, and powder coating present viable options for refining the
final presentation of your custom parts, allowing you to achieve the desired surface quality and
performance characteristics.
3. What is the typical delivery time and quotation process?
Delivery time is determined based on the complexity of the parts. For low-complexity parts,
the lead time is typically 2-3 days. As the complexity of the parts increases, the lead time can range
from 2-5 days. High-complexity parts may require a lead time of 5-15 days.
Similarly, the quotation process varies depending on the complexity of your design. Quotes can be
provided in as little as 1 business day, or it may take 3 or more business days for more intricate
designs.
