China Inverted and External Spiral Coil Brush Manufacturer

Introduction

This brush product, also referred to as a Spiral Brush, Coil Brush, or Formed Strip Brush, is an industrial brush manufactured by forming a strip brush into a continuous spiral coil. By controlling the spiral pitch or using zero pitch, the brush achieves extremely high filament density and uniform contact, making it ideal for precision cleaning, deburring, polishing, and surface finishing applications.

This brush consists of metal backing—typically galvanized steel or stainless steel—and a wide range of filament materials to meet different working conditions. Depending on the direction of the bristle orientation, the brush can be produced as an Inside (Inverted) Spiral Brush, with filaments pointing inward, or an External Spiral Brush, with filaments pointing outward. Each configuration serves different industrial purposes while maintaining consistent and reliable brushing performance.

Spring Coil Brush

Product Features

  • Inverted or External Filament Orientation
    Inside spiral brushes are designed for processing rods, shafts, wires, and tubes, while external spiral brushes function similarly to high-density roller brushes for surface treatment.
  • Custom Spiral Pitch
    Spiral pitch can be precisely controlled from 0 mm (closed coil) up to 310 mm, allowing optimization for contact pressure, cleaning intensity, and material handling.
  • Left-Hand or Right-Hand Winding
    Available in both winding directions to match machine rotation and installation requirements.
  • Custom Inner and Outer Diameters
    The inside diameter and outside diameter can be manufactured to exact specifications for seamless integration with your equipment.
  • Optional Shaft Assembly
    Spiral coil brushes can be supplied loose or fully assembled on a shaft, reducing installation time and improving operational efficiency.
  • Wide Filament Material Selection
    Nylon, polypropylene, steel wire, stainless steel wire, animal hair, and tampico fiber are available to suit different surfaces and operating environments.

Inverted Spring Brush

Applications

The application of the Inverted and External Spiral Coil Brush depends on the filament direction:

  • Inside (Inverted) Spiral Brush
    Used for internal cleaning, polishing, deburring, and surface finishing of rods, shafts, wires, and cylindrical components.
  • External Spiral Brush
    Functions as a high-density roller brush for cleaning, dust removal, surface treatment, and material handling in continuous production lines.

This type of Spiral Brush is widely used in metal processing, wire drawing, tube manufacturing, surface finishing, and automated industrial cleaning systems where consistent contact and durability are critical.
