We have newly developed HaneNight, which enhances vibration-damping performance at high temperature ranges compared to conventional products.

Shock-absorbing and vibration-damping rubber with excellent performance! Outstanding vibration-damping capabilities in the normal temperature range (5-35°C)! Numerous achievements as an anti-vibration material! *Compliant with RoHS2 directive.

The vibration-damping rubber, which excels in shock absorption and vibration absorption, absorbs energy without much rebound even when subjected to external forces. Hanenite GP35LE is the most common grade among Hanenite products. It demonstrates the best vibration-damping properties in the room temperature range. Additionally, it has excellent oil resistance, making it safe to use around various machinery and oil environments. Its physical properties and durability are comparable to those of general rubber. It is widely used as cushioning material and vibration-damping components for quiet and low-vibration products. 【Characteristics】 ● The rebound elasticity is 2% (measured value). ● Load capacity is approximately 800 kg (for 10×100×100 mm with 10% deflection). The values may vary depending on the pressure area, so please contact us for details. ● It can be processed into various shapes. Molding similar to general rubber is possible. Cutting, machining, and punching of sheet materials are also acceptable. ● Strong adhesion with metals is possible. ● Teflon coating (vulcanized adhesion) is possible for surface adhesion prevention and wear resistance improvement. *For more details, please refer to the PDF materials or feel free to contact us.

Twice the shock absorption compared to standard rubber! Ideal for vibration damping in the low-frequency range! Excellent bleed characteristics, with effects over 10 times greater than competing products!

The "Hane Night Gel" has approximately 70% shock absorption when at rest, and about twice the shock absorption compared to regular natural rubber. It also excels in vibration isolation in the low frequency range (21-50Hz). Furthermore, it has superior bleed characteristics compared to gels from other companies that show equivalent hardness. We offer standard gel (HGN-25) and static dissipative gel (HGN-A30). 【Features】 ○ Effective as a shock-absorbing and cushioning material ○ Excellent vibration isolation effect in the low frequency range ○ Superior bleed characteristics (about 10 times more effective than competitors in 1,000 hours) ○ Weather-resistant and suitable for outdoor use ○ Capable of various processing and molding For more details, please contact us or download the catalog.

● 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.
