2000T/M Automatic Vertical Anodizing Line for Architectural
Aluminum Profiles
Overview
This automatic vertical anodizing line is specifically designed for
architectural aluminum profiles including door, window, and curtain
wall profiles. The system integrates Type II sulfuric acid
anodizing, electrolytic coloring, sealing, rinsing, and drying in a
vertical layout configuration.
Available in fully automatic or semi-automatic operation modes with
PLC control, fieldbus communication, recipe storage, and remote
diagnostic capabilities. Complete systems include rectifier power
supply, chiller, filtration, exhaust, and wastewater treatment
components selected according to profile length, load area, and
required film thickness specifications.
Typical film thickness classes include AA15 and AA20, with
electrolytic coloring configurable using tin or nickel salt
systems. Designed for B2B aluminum processors requiring reliable
daily production, controlled process parameters, and maintainable
equipment. Production capacity is project-specific and confirmed
through engineering analysis based on tank size, cycle time, and
profile mix.

Frequently Asked Questions
What is the typical film thickness for architectural aluminum
profiles?
AA15 and AA20 classes can be configured according to project
specification requirements.
Can this line produce electrolytic colored profiles?
Yes. Tin salt or nickel salt electrolytic coloring systems can be
integrated, depending on the required color range and process
design specifications.
Is the line fully automatic?
Fully automatic operation with PLC and fieldbus is available.
Manual override is also provided for maintenance and special
operating conditions.
How is the anodizing temperature controlled?
The line uses a chiller and tank temperature control system. The
cooling medium can be 15-25% sulfuric acid solution or pure water,
depending on system design.
What wastewater is generated?
Acid, alkali and nickel-containing wastewater can be treated by the
configured wastewater treatment system.
Can electrophoresis be added?
Yes. Optional electrophoresis, pure water, paint rectification,
paint recovery and curing oven can be integrated into the system.
