In molding operations within clean rooms, dust and fine foreign substances can adhere to precision parts, leading to quality defects and reduced yield. In particular, fine dust that adheres due to static electricity may not be completely removed by air blowing alone, making it important to implement measures for static elimination and dust removal during the process. Kyoshin Giken offers the production of brushes for static elimination and dust removal using Thunderon fibers. By installing roll brushes at the entrance of the feed and the work process, it is possible to simultaneously remove surface debris and eliminate static electricity when parts are introduced. Additionally, we can accommodate straight brushes and brushes with R edges that can be used with a light touch by operators, allowing for custom production tailored to the working environment and work shapes within the clean room.

When performing polishing or surface treatment on wide workpieces such as steel plates, roll brushes may not provide sufficient extrusion force or processing power because the contact is linear. At Kyoshin Giken, we accommodate the production of thick cup brushes with multiple layers of bristles. Unlike roll brushes that contact the workpiece in a line, cup brushes make contact over a surface, allowing for stable action over a wide area. Additionally, by increasing the thickness of the brush, we can enhance the extrusion force and durability, enabling the configuration of surface treatment specifications tailored to specific applications. By selecting the appropriate bristle materials, we can cater to a wide range of applications, including polishing and surface treatment.

On the conveyor line, dust and product debris may adhere to the surface of the conveyor belt during product transport. Stopping the line to clean off the dirt can lead to decreased production efficiency and increased workload. At Kyoshin Giken, we offer custom manufacturing of roll brushes that can be installed on the return side of the conveyor. The return side refers to the side where the belt returns after completing the transport; by installing the roll brush in this position, the belt surface can be cleaned without coming into contact with the products. By rotating the roll brush in accordance with the movement of the belt, we can remove any adhered substances from the belt surface simultaneously with the transport, thereby contributing to a reduction in the burden of cleaning tasks caused by line stoppages. Custom adjustments can be made based on the width of the conveyor, installation space, and type of adhered substances, including modifications to the bristle material, outer diameter, and brush density.

In a perforating machine that creates fine holes in film, the film may shift or tear during processing with the needle roll. This is particularly true for thin or soft films, where the pressure from the needles can be applied locally, making stable hole processing difficult. At Kyoshin Giken, we respond to the need for high-density roll brushes as receiving side components opposing the needle roll of the perforating machine. The bristles of the roll brush gently support the film while distributing the pressure from the needles, helping to prevent shifting and tearing of the film, thus contributing to stable hole processing. Additionally, the material of the bristles and brush density can be adjusted according to processing conditions, and for applications requiring heat resistance, we can also accommodate heat-resistant bristle materials such as PFA (Teflon-based fluoropolymer) and PPS.

In film perforation processing, it is important to stably support the film during processing with a needle roll. At Kyoshin Giken, we accommodate the production of mixed hair brushes that combine horsehair and wire for perforating machines. Horsehair is flexible and can gently support the film. However, since horsehair alone does not provide sufficient stiffness, we enhance the supporting power by mixing in wire. Additionally, while horsehair and wire mixtures have been commonly used in conventional perforating machines, recent changes in processing conditions have led to higher temperatures of the needle rolls, resulting in more cases where horsehair cannot withstand the heat. As a result, there has been an increase in equipment that employs heat-resistant hair materials such as PFA (Teflon-based fluororesin) and PPS. At Kyoshin Giken, we support not only the heat-resistant hair material specifications that have been increasing in recent years but also the horsehair and wire mixed hair brushes used in conventional equipment.

In the manufacturing process, fine foreign substances adhering to the inside of equipment or the surfaces of parts can affect quality. Especially in processes handling precision parts, even slight adhesion of dust or debris can lead to reduced yield and quality defects. At Kyoshin Giken, we respond to the production of custom brushes used for removing foreign substances from manufacturing equipment and part surfaces. We can accommodate various shapes such as roll brushes and channel brushes, tailored to the structure of the equipment and the target parts. Depending on the type of foreign substance and the removal method, we adjust the bristle material and brush density, proposing brushes suitable for each process. We also have a track record of supplying to battery-related manufacturers, where our brushes are used for foreign substance countermeasures in the manufacturing process.

In logistics and conveying equipment such as belt conveyors, roller conveyors, sorting equipment, and automated warehouses, static electricity can be generated due to friction with the conveyed items.
