Custom Twisted-in-wire brushes


Twisted-in-wire brushes, also known as the spiral, tube, internal cleaning, or simply twisted brushes, are versatile tools widely used in various industries for effective cleaning, deburring, and finishing applications. These custom brushes are made by placing filament materials, such as wire, natural, or synthetic filaments, between two or four stem wires and then twisting them together.

These brushes are ideal for cleaning test tubes, holes, and other intricate areas. They can be used manually or motorized, spinning in a drill or machine for deburring machined holes, for instance. Twisted-in-wire brushes are suitable for preparing surfaces for painting, powder coating, or anodizing and can be made with various filament materials.

Twisted-in-wire brushes Fill Material

Brush filling material refers to the type of bristles or fibers used in a brush. These materials can be natural, like animal hair or vegetable fibers, or synthetic, like nylon or polypropylene. The choice of brush filling material depends on the specific application and desired properties, such as stiffness, abrasion resistance, heat resistance, and chemical compatibility. Different brush filling materials offer various benefits and are suitable for a wide range of cleaning, scrubbing, or polishing tasks.

Nylon is a highly durable synthetic polymer and is resistant to most common chemicals. It has excellent bend recovery and is available in three grades: Type 6, Type 6.6, and Type 6.12. Nylon bristles are suited for cleaning and scrubbing applications due to their strong abrasion resistance properties. They are available in black or natural colors, and diameters range from .003″ to .050″.

This low-cost, high-performance synthetic filament is ideal for wet or dry applications. Polypropylene has excellent stiffness when wet, is inert to most solvents, oils, acids, and chemicals, and is fungus resistant. Filament diameters range from .006″ to .060″, with crimped and level filaments available.

A vegetable fiber obtained from the agava lechuguilla plant, Tampico is suitable for low abrasion scrubbing and washing applications due to its high absorbency rate. It can be used wet or dry and is heat, alkali, and acid resistant.

Soft, resilient, and long-lasting, horse hair is excellent for dusting, flux removal, and general cleanup. It is non-conductive and can be used dry for polishing, scratch-free cleaning, or sweeping in higher-temperature applications.

Also known as Chung King, hog bristle is the stiffest natural material available and provides the best possible cleaning. It is non-conductive and works well for dealing with sticky, crusty materials or viscous fluids.

This highly corrosion-resistant wire is used where contamination or rust is a problem. It is non-shedding and excellent for burnishing without removing the base material.

Offering high fatigue life and durable cutting action, high carbon steel is suitable for work on steel and iron workpieces, as well as wood, aluminum, brass, and copper. Common applications include weld cleaning, deburring, rust and oxide removal, surface preparation, and surface finishing.

We provide a wide range of brush-filling materials to accommodate most applications. Plus, we also directly supply the brush filling, and if needed, we can perform basic processing like cutting it to the desired size. This way, our customers can conveniently work with the brush filling as soon as they receive it.
