Advanced Abrasive Nylon Filament Brushes: Precision Engineering for Industrial Applications
DAMI Brush Filament Company introduces a revolutionary line of abrasive nylon filament brushes designed to redefine industrial surface finishing. By embedding silicon carbide (SiC) and aluminum oxide (Al₂O₃) abrasives uniformly within high-strength nylon filaments, these brushes achieve unparalleled precision in deburring, edge passivation, and surface refinement tasks.

Technical Superiority
- Homogeneous Abrasive Distribution: Advanced manufacturing ensures consistent abrasive particle distribution, enabling uniform material removal and eliminating surface irregularities.
- Form Flexibility: Brushes are customizable in disk, hole, wheel, pen, and bowl shapes to access intricate geometries, including grooves, cross-holes, and threaded components.
- Resilient Construction: The nylon matrix resists degradation from water, oil, and chemical exposure, extending brush lifespan and reducing maintenance costs.
- Conformability: Each filament acts as a flexible file, adapting to workpiece contours while penetrating tight spaces like keyways and slots.

Environmental and Operational Benefits
Compared to sandblasting or vibratory finishing, these brushes operate at lower noise levels and produce zero airborne particles, aligning with stringent environmental regulations. Their chemical inertness further minimizes hazardous waste generation.
Industry-Specific Applications
- Automotive & Motorcycle:
- Deburring engine cylinder heads, crankshafts, and transmission components.
- Surface preparation for painting and coating of body panels and battery tubes.
- Precision finishing of carburetors and fuel injectors.
- Tool Manufacturing:
- Polish and passivate carbide, cermet, and solid carbide cutting tools.
- Enhance tool longevity and cutting efficiency through edge refinement.
- Metalworking (Steel, Iron, Nonferrous Metals):
- Pre-electroplating surface finishing of aluminum profiles and steel components.
- Deburring of cross-holes, ladder holes, and gear teeth.
- Printed Circuit Board (PCB):
- Brass board surface finishing for improved epoxy resin adhesion.
- Deburring and hole cleaning post-drilling operations.
- Woodworking:
- Finishing of three-ply boards and edge refinement for enhanced paint adhesion.
- General Machining:
- Deburring and passivation of internal/external threads, gears, and stepped components.
