Frequently Asked Questions
Q1: Can this line adjust oxide film thickness outside 8-12μm?
The line is optimized for 8-12μm for 3C phone housing. We can adjust parameters for 6-15μm range upon request.
Q2: What sand grain size is matched for fine sandblasting of mobile phone frames?
We support customized blasting media. Standard matching glass bead or alumina sand for delicate matte texture.
Q3: Is the dyeing process able to achieve low-fading requirement for consumer electronics?
We adopt high light-fastness organic dyes with complete sealing process to reduce color fading risk.
Q4: What daily output can this anodizing line reach for aluminum phone housings?
Output depends on fixture layout and cycle time. We provide capacity simulation based on your product dimension.
Q5: Does the equipment support future upgrade for other 3C parts such as notebook frames?
Modular design allows process upgrade for laptop housings, smart watch frames and similar aluminum 3C components.
