Frequently Asked Questions

 
What tolerance can you maintain for the I/O port cutouts? +

We maintain a standard processing tolerance of ±0.1mm for all connector and interface cutouts to ensure exact alignment with your internal PCB components.

What colors are available for the anodizing process? +

Standard anodizing colors include black, silver (clear), and gold. We can also match specific color requirements depending on the production batch size.

Can you install standoffs or mounting points for our circuit boards? +

Yes. We install PEM nuts, threaded standoffs, and custom mounting brackets using press-insertion equipment during fabrication.

How does the aluminum enclosure handle internal heat generation? +

Aluminum provides effective thermal conductivity. We can also incorporate custom ventilation slots or heat sink profiles into the CNC design.

What is the typical material thickness for these electronic enclosures? +

For small to medium precision enclosures, we process aluminum sheets ranging from 1.0mm to 3.0mm, balancing weight reduction with structural rigidity.
