Fine sandblasting dyeing anodizing line

Product Description
30-60T/M Automatic Aluminum Anodizing Production Line for 3C Phone Housing | 8–12μm Fine Sandblasting & Dyeing Process
This dedicated anodizing line is customized for 3C aluminum phone housing mass production. It stably achieves 8-12 μm uniform oxide film with fine sandblasting and consistent dyeing results. Strict parameter locking minimizes color difference and surface defects for consumer electronics standards.
Technical Specifications
Item Technical Parameter
Target Application 3C aluminum phone housing / middle frame
Oxide Film Thickness 8 μm ~ 12 μm (controllable adjustment)
Standard Surface Process Fine sandblasting + anodizing + organic dyeing + hot sealing
Allowable Alloy Series 5052 / 6061 / 6063 aluminum alloy
Color Consistency ΔE ≤ 1.5 under standard light source
Film Hardness ≥ HV320
Production Mode Gantry automatic hanging operation
Tank Material PP anti-corrosion tank body
Control System PLC automatic temperature, time & current control
Production Process
  1. Workpiece loading & fixture positioning
  2. Degreasing and alkaline etching to remove machining traces
  3. Neutralization cleaning to eliminate alkaline residue
  4. Precision fine sandblasting for uniform matte base surface
  5. Secondary pure water rinsing to avoid cross-contamination
  6. DC anodizing to form 8-12μm oxide film
  7. Organic dyeing with constant temperature circulation
  8. Multi-stage pure water rinsing after dyeing
  9. Hot water sealing to lock color and boost corrosion resistance
  10. Final cleaning, air drying & offline inspection

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.
