Proposal for trial production/small-scale processing

Expanded metal is a type of wire mesh that is formed integrally from sheet material, allowing for production without mesh displacement, uniform opening rates, and no material loss. We can achieve small-scale processing with special materials such as chromium-based stainless steel, titanium, nickel, and Inconel, which are difficult to realize with wire mesh. We can process in various ways and deliver in forms tailored to customer requirements. *For more details, please refer to the catalog or feel free to contact us.*

Fukuda Co., Ltd., which develops, manufactures, and sells leak testing equipment to inspect airtightness and sealing performance, provides a technical document that clearly explains the methods and theories of airtight testing, titled "Technical Manual." We are offering it as a PDF file. Please take this opportunity to download and view it!

● What is a hydrogen leak detector? It can measure leaks in small areas that could not be detected in air leak tests and can also identify the leak locations. It is a detector that uses a mixture of 5% hydrogen and 95% nitrogen (non-flammable gas: ISO10156:2017) as the tracer gas. ● What is a helium leak test system? It is a leak test system suitable for high-precision or high-pressure leak inspections. The helium leak test system uses helium gas as the detection gas (tracer gas) and detects the helium that has leaked out. It is the leak test method among Fukuda's leak testers that can detect the smallest leaks.

Fukuda Co., Ltd. has been pursuing leak detection for 60 years and is committed to advancing the future of leak testing. 【 Supporting Various Leak Tests: Air Leak Test / Gas Leak Test (Hydrogen Gas, Helium Gas) 】 We develop, manufacture, and sell leak testing equipment to inspect airtightness and sealing properties. We will propose the appropriate testers and devices for each inspection target. 【 Target Industries and Examples of Inspection Targets 】 - Automotive Industry: Engines, FC components, valves and piping, various parts - Electronic Components Industry: Smartphones, keyless switches, various small sensors - Pharmaceuticals / Food / Cosmetics Industry: Bottle containers, syringes, vials, eye drop containers, pillow packaging, PTP packaging We will propose the most suitable leak testers for each industry. 【 ISO Certification 】JIS Q 9001:2015 (ISO 9001:2015)

In civil engineering sites, there are many instances where sheet boards are used for temporary roads, access routes, heavy machinery work yards, and material storage areas. Traditionally, steel plates have been the mainstream choice, but due to their weight, they require considerable effort for transportation, installation, and removal, which can affect work efficiency depending on site conditions. Hyper CLT sheet boards are civil engineering materials made from CLT, which is wood. While being a sheet board that utilizes wood, it can serve as an alternative to steel plates for measures against muddy conditions, ground protection, and ensuring work pathways. The 5×10 board weighs approximately 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to handle even with small machinery, contributing to reduced handling and construction burdens on site. Additionally, the unique properties of wood help in reducing glare, lowering noise, and fixing CO2, leading to environmentally friendly proposals. By leveraging the characteristics of wood instead of steel, it also aids in improving the working environment during summer and addressing noise issues in surrounding areas. As a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A," it is an easily applicable alternative material for public works that encourages creativity and safety measures. It is recommended for companies considering wood, sheet boards, timber, civil engineering applications, and civil engineering CLT. We also accept requests for materials tailored to site conditions and consultations for implementation. Proposals can be made for both public and private construction projects.

"What is a Hydrogen Leak Detector?" It is a tester that can measure leaks in small areas that could not be measured in air leak tests and can also identify leak points. It uses a tracer gas consisting of 5% hydrogen and 95% nitrogen, an industrial mixed gas (non-flammable gas: ISO10156:2017).
