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.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

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
