Standard Production Process
  1. Loading aluminum interior trim racks
  2. Degreasing & ultrasonic cleaning to remove oil stains
  3. Mechanical brushing to form uniform linear texture
  4. Chemical polishing for smooth metallic base
  5. Neutralization & multi-stage pure water rinsing
  6. Sulfuric acid anodizing to form 8-12μm oxide film
  7. Two optional coloring sections: electrolytic coloring / dye staining
  8. Multi-level deionized water cleaning to remove residual pigment
  9. Medium-temperature nickel salt sealing (core process for interior anti-fading)
  10. Pure water final rinsing
  11. Low-temperature hot air drying
  12. Unloading & finished product inspection
Core Advantages for Automotive Interior Trim Line
  • Stable 8-12μm thin film control, no over-thickness fogging on delicate interior strips
  • Integrated brushing + chemical polishing pre-treatment unit, one-line finish metallic matte base

  • Closed acid circulation & waste acid recovery module, meets global automotive factory environmental audit
  • SPC real-time data recording, provides complete batch test reports for automotive PPAP documents
  • Modular tank layout, easy to expand capacity without full line reconstruction
Complete Supporting Equipment List
  • Automatic gantry handling system
  • Pre-treatment tanks: degreasing, brushing, chemical polishing, neutralization
  • Main sulfuric anodizing tanks + DC stabilized rectifier
  • Electrolytic coloring tank & dye staining tank
  • Medium-temperature sealing tanks with constant temperature control
  • Multi-stage DI water circulation & filtration system
  • Low-temperature drying oven for decorative parts
  • Waste acid recovery & wastewater treatment auxiliary unit
  • PLC intelligent control cabinet + touch screen operation terminal
  • Custom workpiece hanging racks for interior long trim strips
Frequently Asked Questions
Why choose anodizing rather than electrophoretic coating for car interior trim?
Electrocoating fully covers metallic texture, resulting in plastic-looking surfaces. Anodizing reserves natural brushed metal luster, with higher hardness to resist daily finger scratches, matching high-end automotive interior positioning.
Can the line realize wood grain matching anodized tone?
Yes. Our dual coloring system combines electrolytic base tone + trace dye adjustment to reach uniform wood-grain matched finish, widely used in mid-to-high vehicle center console trim.
Is 8-12μm film thickness suitable for all interior aluminum strips?
This thickness is the industry standard for automotive interior decoration: thin enough to keep fine brushed texture, thick enough for scratch & UV resistance inside cabins.
Does medium-temperature sealing cause color difference on piano black parts?
The line equips constant temperature circulation & continuous filtration for sealing tanks, color difference controlled below 0.5% in mass production.
Can the production line pass IATF16949 factory audit?
All process parameters, bath data and product test records can be automatically stored and exported, fully supporting PPAP submission and automotive system audit.
Is the line customizable for small-batch prototype orders?
Yes, we offer semi-automatic compact versions for prototype workshops and full automatic large lines for mass tier 1 manufacturers.
Summary
For automotive interior aluminum decorative trim, customized anodizing production line is the optimal surface treatment solution compared with electroplating or spraying. It delivers delicate brushed metallic texture, stable piano black & wood grain finishes, controlled 8-12μm oxide film and automotive-grade durability. Our modular full automatic anodizing line integrates brushing, polishing, dual coloring and medium-temperature sealing in one set, with environmental auxiliary systems, fully matching mass production demands of auto OEMs and interior part suppliers.
