Ceramic Glaze Line Brush

A Ceramic Glaze Line Brush is a strip brush assembly used on automated glazing lines in tile, sanitaryware, tableware, and technical ceramics production. It consists of a continuous metal or plastic channel that grips a row of filaments—typically horsehair, goat hair, or nylon PA—and mounts along the conveyor or at specific stations where the ware passes.

The brush is positioned so that the filament tips contact the moving ware or line surface. For edge wiping, the brush sits at an angle or horizontally so the trim deflecting against the edge removes glaze that has wicked around the sides or back. For dusting and carrier cleaning, the brush is set with lighter contact to sweep loose particles without pressing the ware. For sealing, the brush is mounted with higher compression to fill gaps that would otherwise let glaze mist escape.

The working principle is deflection, not scrubbing: the brush is mounted so the trim height is compressed by a fixed percentage, and that compression determines how much contact force the filament tips apply. We specify 5–15% compression for wiping and dust control and 10–25% for sealing or heavier edge contact. Beyond that, the fill can crush and wear prematurely.

This is a consumable line component. It is replaced when the filaments wear short, break, or lose their set, and it is not intended for removing fired glaze, hard deposits, or scale.

All dimensions are customizable. The values shown represent the standard production range; contact width, trim height, and holder profile are set to your line geometry.

• Tile glazing lines: Wiping excess glaze from tile edges and backs before the tiles enter the kiln, preventing glaze transfer and sticking in the firing process.
• Sanitaryware production: Removing glaze drips from rims, feet, and hidden surfaces after dipping or spraying, where precise soft contact is required.
• Tableware and artware: Dusting bisque ware and wiping glaze lines or decorative edges where a soft, controlled contact preserves surface quality.
• Technical ceramics and ferrite processing: Cleaning carriers, substrates, and precision surfaces after machining or polishing, and removing dust before coating or sintering.
• Conveyor belt and roller maintenance: Keeping the glazing line’s own transport surfaces free of glaze build-up, overspray, and ceramic dust, which reduces random defects on subsequent ware.

Start with the contact zone. Measure the width of the ware or line section you need to wipe or seal. Choose a strip length that covers the full zone in one section, or plan joints for longer lines. For tile edge wiping, the brush length typically matches the tile width or the conveyor width for full-line coverage.

Set the trim height for your mounting space and wear life. Higher trim gives more deflection range and longer life before replacement, but requires more vertical space above the line. Lower trim fits tight machine envelopes but wears faster and needs more frequent replacement.

Match the channel to your mounting hardware. If you already have an aluminum extrusion or t-slot rail, a straight channel or aluminum carrier may slide in. If you need a 45° or custom angle to contact the ware edge, specify an angle holder. The channel width must also fit the rail groove or bracket slot.

Choose the fill material by residue and environment:

• Horsehair: Soft, resilient, mildly absorbent. Good for dry dusting, wiping light glaze from green or glazed ware, and fine edge contact. Avoid continuous wet or chemical exposure.
• Goat hair: Softer and finer than horsehair, ideal for very delicate bisque or polished surfaces and ultra-fine dust. Wears faster under abrasion.
• Nylon PA: Moisture and chemical resistant, stiffer at a given diameter, and more wear resistant. Use for wet glaze lines, slurry contact, and heavier wiping. Select a smaller filament diameter if you still need soft contact.

Decide the working compression. 5–15% of trim height for wiping and dust control; 10–25% for sealing gaps or removing heavier glaze build-up on edges. Never exceed 25%—the fill will crush and lose contact.

Consider line speed and ware weight. Faster lines and heavier ware require slightly higher compression or a stiffer fill to maintain contact without bouncing. Test on a line sample before full installation.

When to use a different brush. If you need to remove fired glaze, scale, or hard deposits, this brush is not suitable—use an abrasive or wire brush. If you need to apply glaze rather than wipe it away, a glaze application roller or spray system is the right tool. For very high-temperature zones near the kiln, confirm fill temperature limits before ordering.

Ceramic glaze line brushes are configured to each line because mounting geometry and contact requirements vary widely. We can adjust the following:

• Strip length: 100–3000 mm per section, and multi-section assemblies for longer lines.
• Trim height and filament diameter: Within the ranges shown, selected for contact force, conformability, and wear life.
• Fill material and density: Horsehair, goat hair, nylon PA, or blends; rows per cm adjusted for wiping, dusting, or sealing.
• Channel and holder: Straight channel, aluminum carrier, angle holder, or custom profile to match your mounting rail; pre-drilled mounting holes or quick-change clamps.
• End trimming and edge shape: Beveled ends, notched sections, or segmented strips to fit around line obstacles.
• Color and marking: Colored filament, channel marking, or identification labels for different line positions.
• Packaging: Bulk, per-section, or line-set packaging with installation instructions.

To define a custom configuration, provide the line width and ware dimensions, distance from the mounting surface to the contact point, available mounting space, glaze type (wet or dry, chemical additives), line speed, compression target, and any existing mounting profile or drawing. A photo or CAD sketch of the mounting location speeds up the design.

If your project requires material documentation, inspection reports, or third-party testing for quality or export requirements, we can assist during the customization process.
