The large 3D vibration table has been featured in the newspaper.

The largest large-scale shaking table in the country can reproduce seismic motions such as those from the Great East Japan Earthquake, which are difficult for other companies to replicate, with 100% accuracy! In addition to seismic resistance testing, transportation tests can also be conducted.

The Japan Oceanographic Science YOKOHAMA LAB (Isogo Ward, Yokohama City, Kanagawa Prefecture) conducts commissioned vibration tests, including the reproduction of various seismic waveforms such as those from the Great East Japan Earthquake. It provides data necessary for strength calculation verification of products requiring seismic performance, including acceleration response spectra, acceleration time histories, displacements, and resonance points, enabling advanced evaluation tests. *Due to a company split, the vibration table business of MTI Co., Ltd. was transferred to Japan Oceanographic Science Co., Ltd. in April 2022. The shaking table is large, measuring 2.6×6.2m, and can perform 2-hour vibrations with minimal waiting time for multiple vibrations (with a maximum of 123 vibrations per day in the past). It also accommodates actual transport vibrations from trailers, railways, and ships, as well as transportation vibration tests according to JIS and ASTM standards. The photo shows a test using approximately 8 tons of water (published with permission from Ace Water Co., Ltd.). 【Actual Earthquake Waveforms】 Great East Japan Earthquake / Niigata Chuetsu Earthquake / Hanshin Earthquake / Noto Peninsula Earthquake, etc. 【Artificial Earthquake Waves Held】 ○ NTT Docomo artificial earthquake waves, NTT ○ NEBS (GR-63-CORE zone4) 【Transportation Standard Tests】 ○ JIS Z 0200/0232, ASTM D4169, etc. ● For more details, please contact us.

Faithfully reproduce the vibrations of cargo during transportation!

At the Yokohama Lab of Japan Marine Science (located in Isogo Ward, Yokohama City, Kanagawa Prefecture), we contribute to the examination of optimal loading methods for transported cargo and the investigation of damage causes by reproducing the vibrations and motions that cargo encounters during transport for testing. *Due to a company split, the demonstration testing business utilizing the vibration table of MTI Co., Ltd. was succeeded by Japan Marine Science Co., Ltd. as of April 1, 2022. We have established a system to conduct vibration tests that meet the newly added standards applicable to IBC containers for storing liquid hazardous materials manufactured, repaired, or modified after January 1, 2011. (This vibration test has also been confirmed by the Japan Ship Equipment Inspection Association as of the end of August 2010.) 【Actual transport vibration waves held (for cargo vibration reproduction testing)】 Rail transport vibration wave: Vibration of double-stack trains on North American inland cross-continental railroads Trailer transport vibration wave: Vibration of trailers traveling on metropolitan expressways 【Standard vibration waves held】 JIS Z 0232 ● For more details, please download the catalog or contact us.

● To determine the sealing and waterproofing of sealed products based on pressure changes, it is not necessary to conduct tests that involve spraying water on the product or immersing it in water. ● Once the product is placed in a dedicated fixture within the inspection device, waterproofing can be quantitatively confirmed through automatic measurement. ● The target product size is W 300 × D 210 × H 100 mm or smaller. ● The target products include automotive cameras, smartphones, ECUs, small motors, and other packaging containers, and are effective for any products that require confirmation of sealing, waterproofing, and airtightness. ● For product specifications and details, please contact us.

In battery manufacturing lines, if components containing copper are used, there is a possibility that metal powder may mix in, dissolve, ionize, and pass through the separator, causing a malfunction that connects the positive and negative electrodes. Such minute metal powders may not be detected during pre-shipment inspections, and even if they are found, they can lead to various issues, such as the need to increase inspection processes to detect them. Therefore, Fukuda has developed a copper-free (all stainless steel) air leak tester that can be safely used in the production lines of battery manufacturers and secondary battery manufacturing equipment manufacturers. For product specifications and details, please refer to the "Related Product Information" and "Related Catalogs" below.

This is an air leak tester for battery cases of electric vehicles (EVs). The battery case has the characteristic of being "large with a significant internal volume, and its structure may deform due to internal pressure." As a result, air leak testing generates "noise caused by its large size and capacity" and "noise caused by expansion or deformation due to internal pressurization." To mitigate this noise, this device features a newly developed smoothing function and a linear fitting correction function used in combination during measurement. Additionally, to achieve low-pressure control that is difficult to manage and to expand flow for large volumes, we provide a bypass box (CBU-600) equipped with an electro-pneumatic regulator for precise pressure control and a pressurization valve with a large effective diameter to supply high flow rates. Measurement methods: Work-Work comparison, Work-Master comparison, Fixed Master comparison Measurement pressure range: 10 kPa, 20 kPa, 50 kPa (depending on specifications) Gauge pressure sensor accuracy: ±2% F.S. Differential pressure sensor accuracy: ±0.5% F.S. Group settings: 0 to 31 groups Power supply voltage / Power consumption: AC100 to 240 V / 100 VA

Fukuda's new flagship model. - Masterless type (FLA-0200 series) - General type (FLA-0201 series) Two models of air leak testers. With the mastering correction function, high-precision measurements can be achieved in a short time. Please take a look at the catalog.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.
