● What is a pneumatic regulator? It is a self-developed pneumatic regulator with a control reproducibility of ±0.1%. We offer a wide range of products from low flow to high flow. ● What is a regulator? Please use it to adjust the test pressure for leak testing. By supplying a stable test pressure, it enables more accurate measurements.

Fukuda Corporation has been pursuing leak detection for 60 years and is dedicated 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 performance. We will propose suitable 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 a civil engineering site material yard, not only is material storage conducted, but also the frequent movement of trucks and heavy machinery, unloading, and the movement of workers. On unpaved ground, mud and ruts can occur due to rain, which may reduce work efficiency. Hyper CLT mats are civil engineering CLT materials that utilize wood CLT. By laying them in material yards or storage areas, a work space that facilitates the movement of vehicles and heavy machinery can be established while protecting the ground. They can be laid only in necessary locations, and relocation or repurposing in accordance with construction progress is also possible. The 5×10 panel weighs approximately 230 kg, and the 5×20 panel weighs about 460 kg, making them lightweight and easy to install and remove even with small machinery. After use, they can also be utilized as temporary roads, access routes, or heavy machinery work yards. Additionally, they offer unique benefits of wood, such as glare reduction, noise suppression, and CO2 fixation. As a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A," these wooden mats can also be used for environmental improvement in material yards and innovative public works.
