We would like to introduce a case study of the "Fuel Cell Filter" produced by our company. It is possible to achieve a clean finish by performing bright annealing (a heat treatment method) in a non-oxidizing atmosphere to eliminate welding burn that occurs during processing. We can process wire mesh into the desired shape. Additionally, we can accommodate everything from prototype production to mass production through integrated manufacturing. 【Case Overview】 ■ Type: Welded type, Stamped type ■ Application: Fuel cell vehicles, etc. ■ Size: Customizable ■ Material: We respond to customer requests with various materials and shapes. *For more details, please download the PDF or feel free to contact us.

Leveraging our technology in the manufacturing of small metal mesh filters, we have developed a high-pressure resistant mesh filter for dispensers at hydrogen stations. Using sintered metal non-woven fabric made from fine metal fibers at the micron level, it maintains a high porosity while offering excellent filtration precision of 2µm and above. It is also capable of withstanding hydrogen pressures of over 100MPa and exhibits excellent heat and corrosion resistance. [Case Overview] ■ Type: Spot welding type ■ Application: Dispensers for hydrogen stations, etc. ■ Size: φ6 and above *Customizable ■ Material: Metal non-woven fabric, SUS316L *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study of the "Air Conditioner Related Filters" produced by our company. These filters are used in air conditioners, automotive air conditioning systems, etc. It is also possible to weld mesh to ensure a sufficient filtration area. Additionally, the wire mesh can be reinforced with a double structure. Please feel free to contact us if you have any requests. 【Case Overview】 ■ Type: Riveting, Spot Welding, Resin Molding ■ Application: Filtration of foreign substances and contamination ■ Size: Customizable (with production records for outer diameters from φ6) ■ Materials - Wire mesh: SUS304, SUS316, brass, etc. - Ring: Brass, stainless steel, copper, etc. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study of cost reduction and quick delivery achieved through automated processing for overseas manufacturer Company I, which produces gas safety devices. The company was purchasing resin-molded filters from existing suppliers but was struggling to address frequent defects. Additionally, since they required inexpensive yet high-quality products, pricing was one of the challenges for us. We solved the customer's problem by providing consistent production from wire mesh molding to riveting using our in-house designed automated processing machines. Since starting our business relationship, we have not received a single complaint and continue to work together as a good business partner. [Case Overview] ■ Issues and Requests - Frequent defects that were difficult to address - Request for inexpensive yet high-quality products ■ Solution - Consistent production from wire mesh molding to riveting using in-house designed automated processing machines *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where we resolved the fraying of the wire mesh of a "metal filter with an outer diameter of φ6" to Company I, an overseas manufacturer of gas safety devices. The company expressed concerns that the debris from the wire mesh of our product might mix into the next process and inquired if it could be improved. Our technical department suggested changing the cutting direction of the wire mesh, and when we produced it with a diagonal cut, the occurrence of fraying was reduced, as anticipated by the technical department. [Case Overview] ■ Issues and Requests - There were concerns that debris from the wire mesh might mix into the next process. ■ Solution - Produced with the wire mesh cut diagonally, which reduced the occurrence of fraying. - Successfully resolved the user's issue while keeping additional costs down. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study that solved the challenges of mesh filters to overseas manufacturers that produce gas safety devices. We received a request to reduce the cost of metal mesh filters purchased from existing suppliers. The current product is a coin filter made by crimping two types of metal mesh with different mesh sizes using stainless steel plates. Our company proposed a molded product made solely from metal mesh. Since only metal mesh is used, we were able to reduce material and processing costs, and furthermore, we could manufacture it with fewer molds than the current product, significantly lowering the initial costs. [Case Overview] ■ Issues and Requests - Cost reduction of metal mesh filters purchased from existing suppliers ■ Solutions - Proposal of molded products made solely from metal mesh - Reduced material and processing costs, significantly lowering initial costs *For more details, please download the PDF or feel free to contact us.

We received a request from an automotive parts manufacturer to improve the quality of their current products, and we would like to introduce a case study that solved the issues with mesh filters. The filter was made of welded wire mesh, but during the welding process, heat caused discoloration and oxidation, resulting in blackened areas. This discoloration not only affected the appearance but also raised concerns that if left unaddressed, corrosion could progress from the burned areas and erode the surrounding material. We proposed the removal of welding burn marks through bright annealing treatment. This successfully eliminated oxidation from the welded areas and maintained the durability and performance of the machinery. [Case Overview] ■ Issues and Requests - Occurrence of welding burn marks leading to black discoloration and oxidation - Concerns about potential erosion of surrounding areas ■ Solution - Proposed removal of welding burn marks through bright annealing treatment - Successfully maintained the durability and performance of the machinery *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study of a mesh filter for biofuels that we manufactured for Company K, which produces injectors for biofuel vehicles. The company had been using nylon mesh resin molded filters for fuel filtration, but encountered a problem where the nylon mesh deteriorated and melted during use. The cause of the nylon mesh melting during use was the ethanol contained in the biofuel. By using our metal mesh filter, which does not dissolve in ethanol, we were able to solve the problem. 【Case Overview】 ■ Issues and Requests - Fuel filtration is important, but the nylon mesh deteriorates and melts during use. ■ Solution - Use our metal mesh filter, which does not dissolve in ethanol. - Manufactured a high-quality filter with high durability and continuous use capability while maintaining functionality. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where we manufactured a long filter, approximately 1 meter in length, used in an old type of rolling mill. Due to the aging of the craftsmen who have been producing these filters, it will become difficult to obtain them in the future, so we were approached as a new supplier. The specifications of this filter are approximately 1 meter in length, with a spring-like coil inside the rolled mesh for reinforcement. [Case Overview] ■ Challenges - Since multiple filters are used in a single rolling mill, they must not interfere with each other. ■ Solution - By creating a simple jig, we were able to easily insert the coil into the tube, making mass production feasible. *For more details, please download the PDF or feel free to contact us.

Strainers/mesh filters and filters refer to "filtration devices." The shape and material vary depending on the installation location and purpose, but both filters and strainers serve the same function. They may simply be referred to as strainers or filters, or by names such as strainer mesh, mesh filter, mesh screen, or strainer filter, depending on the customer. The purpose of a strainer is to purify all types of fluids, including gases, liquids, solids, sound, and light, to achieve a pure state.
