A chemical-resistant strip brush that mounts along anodizing and metal-treatment lines to wipe excess solution, remove oxide and salt residue, and control fluid carryover. Continuous channel construction holds a dense filament line against moving parts, rollers, and tank edges without leaving untreated gaps.
What can this brush do for you?
Holds an Unbroken Contact Line Across the Full Pass Width
Because the brush is built as a continuous channel-retained strip, the filament fill runs without gaps along the entire mounting length. When the brush contacts a moving strip, sheet, or profile, every point on the pass width sees the same filament density—no dead zones where oxide, salts, or electrolyte film can stay behind.
Cleans the Residues That Anodizing Lines Produce Every Shift
Anodizing generates aluminum oxide, smut, dried salts, and chemical film that collect on rollers, contact points, racks, and tank edges. A silicon carbide abrasive nylon fill gives the brush enough cutting action to dislodge this residue during normal line movement, so it does not build up into a hard layer that shortens roller life or marks the part.
Adjusts Between Light Wiping and Positive Gap Sealing
The brush works within a defined compression window—typically 5–15% of trim height for wiping and dust control, 10–25% for sealing without crushing the fill. Setting the mounting position within this range changes the contact force without changing the brush itself, so one brush can be tuned to the stage it serves.
Survives the Acid and Alkali Stages of Anodizing
Polypropylene and PBT filament options tolerate the acidic electrolyte, rinse water, and alkaline etching conditions common on anodizing lines. The choice between them depends on temperature, chemical concentration, and how much mechanical wear the contact surface applies to the brush.
Mounts Into Existing Line Hardware Without a Redesign
Straight channel, aluminum carrier, and angle holder options let the brush fasten to existing rails, brackets, or machine frames. Custom lengths up to 3000 mm reduce the need for splices, and end features can be machined to fit the line’s existing mounting points.
What is an Anodizing Line Brush?
An Anodizing Line Brush is a linear strip brush—a continuous channel back filled with dense synthetic filament—mounted along a metal treatment line as a fixed or spring-loaded contact element. The strip, sheet, or profile moves past the brush, or the brush moves with a carriage, while the filament tips wipe, scrub, or seal the surface.
On anodizing lines, this brush normally performs three jobs: it wipes excess electrolyte or rinse water from the material as it leaves a stage, it cleans oxide and salt deposits from rollers, racks, and contact points as they pass, and it seals small gaps between process areas to reduce chemical mist and drag-out.
The brush is not a handheld scrub brush for cleaning tank interiors. It is a line-mounted component designed for continuous contact with moving production. Filament type, filament diameter, trim height, and working compression determine how aggressively it cleans and how long the fill lasts under the line’s chemistry and speed.

Where does this brush work best?
- Wiping strip and sheet after rinse stages — removes excess water and electrolyte film before drying or sealing.
- Cleaning conveyor rollers and contact points — silicon carbide abrasive nylon fill removes aluminum oxide, smut, and dried salts that would otherwise build up and transfer onto the work.
- Sealing tank and enclosure gaps — dense fill run at 10–25% compression reduces chemical mist, spray, and drag-out between process areas.
- Conditioning racks and jigs — filament tips scrub contact points where oxide grows during repeated anodizing cycles.
- Guiding and supporting profiles — soft PP or PA fill can support thin or flexible extrusions while wiping surface residue.
How do I choose the right one?
Start from the line’s physical constraints and the residue you are actually fighting. The right brush is a combination of mounting fit, filament material, and working compression—not a single default product.
Measure the Contact Line and Mounting Zone
Record the full contact width, the clearance between the brush back and the moving surface, and the available mounting face. Longer strips reduce splices, but if the line has fixed bracket positions, match the strip length and end machining to those points. Channel width must fit the retainer or carrier you plan to use.
Match the Filament to the Chemistry and the Residue
For hardened oxide, salts, and plating residue on rollers or contacts, use silicon carbide abrasive nylon—it cuts without scratching the aluminum work surface as aggressively as wire. For acidic or alkaline stages where chemical resistance is the priority, PBT is usually the better choice. Polypropylene offers good chemical tolerance at lower cost for less abrasive jobs and light wiping. Nylon PA is a flexible general-purpose option for wet lines with moderate wear.
Set Trim Height and Compression for the Task
Longer trim height allows greater filament deflection, which is useful for uneven or moving surfaces. Thicker filament diameters provide more scrubbing force and longer life but less conformability. Start with 5–15% compression for wiping and dust control; move toward 10–25% only when you need a positive seal. Compressing beyond 25% bends the filament permanently and shortens fill life.
Know When a Different Brush Is the Better Tool
If the residue is heavy scale, burned deposits, or requires aggressive stock removal, a disc or cup brush with abrasive filament or wire may be more effective. If the process temperature exceeds the filament material’s rated range, a stainless steel wire strip brush should be considered. If the application requires a metal-free contact surface, specify polymer filament with a polymer or non-metallic backing to avoid any metal transfer.
Can I customize this brush?
Anodizing line brushes are built to the line, not pulled from fixed stock. We need the following from you: contact width, available clearance, holder or mounting style, line speed, process chemistry (including temperature), and the specific residue you want to remove. A photo or drawing of the mounting position is useful.
- Length and trim height — cut to the exact pass width within 100–3000 mm; trim height from 12.7 to 152.4 mm.
- Filament material and diameter — SiC abrasive nylon, PBT, PP, or PA; filament diameter from 0.10 to 1.27 mm; density adjusted for stiffness and flow-through.
- Holder and mounting interface — straight channel, aluminum carrier, angle holder, custom profile, end brackets, or bolt slots matched to existing hardware.
- End treatment — cut square, notched, drilled, welded, or finished to your mounting pattern.
- Color and marking — filament color coding by stage, channel marking, or identification tags.
- Packaging — bulk, individual protection, or line-kit packaging with multiple strips.
If your project requires material declarations, inspection documents, or third-party testing support, we can arrange those as part of the customization scope.
How do you tell when an anodizing line brush is worn out?
How do I know the brush is set at the right compression on the line?
Measure the filament tip position with the brush in contact. The deflection should fall between 5% and 25% of the trim height. If the tips flatten against the back or stay permanently bent after the line stops, the compression is too high; if the tips barely touch and residue remains on the part, raise the mounting position or move the brush closer.
What should a weekly inspection cover?
Check for uneven filament wear, chemical matting, broken or missing filaments, and loose retainer or mounting fasteners. Clean any sludge or salt buildup from the brush back. If the fill no longer recovers its original shape after compression, or if the contact line has visible gaps, replace the strip.
Can this brush remove heavy aluminum oxide scale from racks and jigs?
It removes the soft oxide film and salt residue that builds during normal anodizing cycles. Hard, crystalline scale or heavily burned deposits may require a dedicated rack-stripping process with a cup brush, wire brush, or chemical stripping before the line brush can maintain the surface afterward.
Does the line brush replace the degreasing or etching step?
No. The brush wipes, cleans, and seals surfaces, but it does not chemically prepare the metal. Degreasing, etching, and desmutting must still be performed according to the process specification. The brush controls what is carried between stages and keeps line equipment clean, which supports those steps rather than replacing them.
What line speed can this brush handle while wiping?
It depends on filament material, diameter, trim height, and chemistry. As a practical starting point, test at typical anodizing line speeds of a few meters per minute for wiping operations. For sealing applications where the brush acts as a physical barrier, speed is less limiting than consistent compression across the strip. Run a trial with the actual chemistry before committing to a full line set.
Can the brush run continuously in a hot sealant bath?
It can if the filament and backing materials are selected for the sealant temperature and chemistry. PBT and PP handle moderately elevated temperatures, but their limits are lower than stainless steel. Specify the actual sealant temperature and immersion or contact condition during customization so the fill and backing are rated for that environment.
