A twisting brush is a brush that is manufactured by sandwiching a brush bristle material between two or more core wires and twisting it.
It is also called a tube brush or condenser brush depending on the manufacturer and region, but Hashimoto Brush Mfg. Co., Ltd. describes it as a twisted brush.
At our factory, we have devised a special method for arranging hair, such as those with long hair that are difficult to manufacture with an automatic machine.
We also manufacture brushes with a brush diameter of φ0.4 mm, a brush with a large outer diameter of φ100 mm or more, and a brush with a total length of 5 meters or more.
How to wind the twist brush
- Single spiral
- Arrange the hair material in the center of the two wires and screw it in. This is a common method for twisting brushes. Ideal for cleaning.
- 4 spiral
- Arrange the hair material in the center of the four wires and screw it in. Since the core wire is held stronger than the single spiral, it is ideal for cleaning with stronger hair.
- Double spiral
- Arrange two rows of bristle material between the four wires and twist. Compared to single hair, it has more hair and a uniform density. Polishing and deburring. Ideal for precision finishing.
Processing example
- Tip bending
- Ideal for preventing scratches on the tip and cleaning the bottom.
- With tip
- Ideal for items such as test tubes and bottles that have a small insertion port and a wider area to be cleaned than the insertion port.
- Rose tip
- The tip is bent into a circle. Ideal for shapes where the bottom is closed with a cylinder such as a cup or cap.
- U-turn twist
- The core wire at the tip is U-shaped, making it ideal for preventing scratches at the tip.
- Taper brush
- We will taper to any angle.
- Concentric bending brush
- A cleaning brush that features one or more turns of the tip of the brush.
- Other bending process
- We will perform processing such as folding in half, angling at any angle, L bending, C bending, etc.
- Nylon scrubbing brush
- There are 3 types: single spiral, 4 single spiral, and double spiral. Soft type / hard type
- Joint series
- Easy-to-replace brush with M6 screws. Brush outer diameter Φ8mm ~ Φ300mm or more can be manufactured.
