We would like to introduce a case where we produced a product referred to as a channel cup brush with fittings. We created a double-row cup brush with different outer diameters, fixed by welding. Additionally, we attached the necessary fittings for installing the brush onto machines and other equipment. Since the channel is made of metal, it can be directly attached to the channel part through welding. As a result, concerns regarding weight and other issues can be eliminated. Our company manufactures and sells custom industrial brushes with short lead times, starting from a single unit. 【Case Overview】 ■ Created a double-row cup brush with different outer diameters, fixed by welding ■ Attached necessary fittings for installing the brush onto machines and other equipment ■ The channel is made of metal, allowing for direct attachment to the channel part through welding ■ Concerns regarding weight and other issues can be eliminated ■ Brush material used is nylon with a diameter of 0.3 mm *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case of manufacturing a product that we call a channel cup brush with fittings. The manufacturing method is similar to that of a regular cup brush. First, we create the brush in a straight line. Then, we perform bending processing to shape it into a cup. The hair material is cut while in a straight state, based on a template, and done manually. Our company manufactures and sells custom industrial brushes with short lead times, starting from a single unit. 【Case Overview】 - The brush is cut in a serrated manner while in a straight state, and bending processing is carried out in a later step. - Even small brushes with an outer diameter of Φ45mm and a hair length of 10mm can undergo this processing. - The cutting is done manually based on a template while in a straight state. - By extending the tips, the brush can effectively reach the desired areas. *For more details, please download the PDF or feel free to contact us.

We would like to introduce the fiber material called "Kornex" that we handle. It is a material with excellent resistance to high temperatures, with a melting point of 280°C and a maximum usage limit of below 200°C. It is resistant to most acids, alkalis, and organic solvents. We recommend this fiber material for environments where brushes are used under special conditions (high temperatures or chemicals). We can provide samples of the fiber material, so please feel free to contact us. Our company manufactures and sells custom industrial brushes with short lead times, starting from a single unit. 【Case Overview】 ■ A material known as ultra-heat-resistant fiber with excellent resistance to high temperatures ■ Melting point of 280°C, maximum usage limit below 200°C ■ Resistant to most acids, alkalis, and organic solvents ■ The stiffness feels crisper compared to PP (polypropylene) ■ We handle yellow fibers with diameters of Φ0.25 and Φ0.35 *For more details, please download the PDF or feel free to contact us.

Regarding the "width" of the bristle tips of the channel brushes manufactured by our company, we would like to explain. Even if brushes are made with the same gauge channel using different types of bristles, wire diameters, or wave processing, the width can vary. Therefore, we kindly ask for your understanding that we cannot accommodate requests for "specific bristle tip widths." Our company manufactures and sells custom industrial brushes with short lead times and from a minimum order of one piece. 【Overview】 ■ The width varies depending on the type of bristle ■ Specific width requests for bristle tips are not possible ■ Minor adjustments to channel width are possible *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case of producing small straight brushes at our company. The photo shows a large number of channel straight brushes. The size is 20mm wide and 30mm high. Even such a small brush works effectively. Additionally, it is common to receive large orders for small brushes. There are possible dimensions for production depending on the channel size, so please inquire. Our company manufactures and sells custom industrial brushes with short lead times, starting from a single unit. 【Case Overview】 ■ Size: 20mm wide, 30mm high ■ Possible dimensions for production vary by channel size, so please inquire ■ Each brush is made by hand ■ If the quantity is large, there may be a risk of extended lead times *For more details, please download the PDF or feel free to contact us.

Our company manufactures brushes using what is called "plant fibers." As the name suggests, "plant fibers" are hair materials made from plants. There are three types: "pakin," "palm," and "fern." We differentiate the use of plant fiber materials according to the work, just like other fiber materials. Our company manufactures and sells custom industrial brushes with short lead times, starting from a single unit. We look forward to your wonderful inquiries and consultations about our brushes. [Types] ■ Pakin ■ Palm ■ Fern *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where we welded channel straight brushes onto flat bars. While it is common to attach brushes to fittings using welding, in this instance, we attached brushes to both the front and back sides of the flat bar. Additionally, the small brushes have a processing called "notching." Our company manufactures and sells custom industrial brushes with short lead times, starting from a single unit. [Case Overview] ■ Welded channel straight brushes onto flat bars ■ Attached brushes to both the front and back sides of the flat bar ■ Small brushes have a processing called "notching" *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where we manufactured a brush with bending and straight sections. Using a specialized machine for bending, we processed the brush according to the specified radius provided by the customer. We adjusted the length to ensure that the straight sections were well-preserved and made fine adjustments to match the prepared template. While the rough parts were processed using machines, the final assembly was completed by hand. Our company manufactures and sells custom industrial brushes with short lead times, starting from a single unit. [Case Overview] ■ Brush with bending and straight sections ■ Processed using a specialized machine for bending according to the specified radius ■ Length adjusted to preserve the straight sections ■ Fine adjustments made to match the prepared template ■ Rough parts processed by machine, final assembly completed by hand *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where five channel straight brushes were arranged side by side and attached through welding at our company. A round bar was attached to the brush, which is now a single unit, serving as a handle. While there are occasional cases of brushes arranged horizontally like this, the addition of a handle in this instance is quite rare. Our company manufactures and sells custom industrial brushes with short lead times, starting from a single unit. 【Case Overview】 ■ Five brushes arranged side by side and attached through welding ■ Round bar attached as a handle ■ Attached from the back through welding ■ Shaft and channel attached through welding *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where a channel linear brush was attached to a flat bar. The feature of this case is that the brush bristles are facing each other. Common examples are inward-wound coils or inward-wound ring brushes, but this time it was a rare case with a linear brush request. Our company manufactures and sells custom industrial brushes with short lead times and from a single unit. 【Case Overview】 ■ Channel linear brush attached to a flat bar ■ Brush bristles are facing each other ■ A workpiece is passed through the center to remove dirt and other contaminants ■ Bristles made of PPΦ0.3 with waves are used ■ The bristles are designed to overlap in the center to increase resistance *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where we performed bending processing on a channel straight brush to fit within the range of the metal fittings. Since it is physically impossible to bend a brush of this width as shown in the photo, we used two brushes to achieve the desired width. They are then attached to the metal fittings using welding.
