process

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
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
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
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

Processing example
Tip bending
Ideal for preventing scratches on the tip and cleaning the bottom.
Processing example
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.
Processing example
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.
Processing example
U-turn twist
The core wire at the tip is U-shaped, making it ideal for preventing scratches at the tip.
Processing example
Taper brush
We will taper to any angle.
Processing example
Concentric bending brush
A cleaning brush that features one or more turns of the tip of the brush.
Processing example
Other bending process
We will perform processing such as folding in half, angling at any angle, L bending, C bending, etc.
Processing example
Nylon scrubbing brush
There are 3 types: single spiral, 4 single spiral, and double spiral. Soft type / hard type
Processing example
