Evaluation of the rebound and vibration absorption properties of rubber materials.

Introduction of examples of "temperature dispersion measurement" and "frequency dispersion measurement - master curve."

We would like to introduce a case where the rebound and vibration absorption properties of rubber materials were evaluated using dynamic mechanical analysis (DMA). In the "Comparison of Vibration Absorption of Rubber (Temperature Dispersion Measurement)," dynamic mechanical analysis was conducted using two types of rubber materials. Rubber A is considered to have superior vibration absorption properties (lower rebound) than Rubber B, with larger E" and tanδ in temperature ranges above -10°C. In the "Comparison of Vibration Absorption of Rubber (Frequency Dispersion Measurement - Master Curve)," the dynamic mechanical properties of Rubber A and B were compared across frequencies. By creating a master curve, it is also possible to predict the viscoelastic behavior in frequency ranges that cannot be directly measured. 【Measurement Details】 ■ Comparison of Vibration Absorption of Rubber (Temperature Dispersion Measurement) - Rubber A is considered to have superior vibration absorption properties (lower rebound) than Rubber B, with larger E" and tanδ in temperature ranges above -10°C. ■ Comparison of Vibration Absorption of Rubber (Frequency Dispersion Measurement - Master Curve) - Rubber A is considered to have superior vibration absorption properties than Rubber B, with larger tanδ across a wider frequency range. *For more details, please download the PDF or feel free to contact us.

In recent years, we have received numerous requests for extending the lifespan of operational equipment. With the advancement of high functionality in both equipment and components, the specialization of repair services has progressed. Along with this specialization, it has become increasingly difficult to provide comprehensive "repairs" through integrated diagnostics and verification. With the establishment of this service center, we will offer one-stop regeneration and lifespan extension through "comprehensive diagnostics of equipment" by our skilled engineers and the "integration of specialized techniques" from partner engineers located nationwide.

Insulating oil from old electrical equipment that has been in use for over 30 years may be contaminated with PCBs. Proper disposal is required by the disposal deadline. If you are using a vacuum tube oscillator, please check! - Transformers - Capacitors - Rectifiers, etc. Please consider updating any relevant equipment such as oscillators and hardening equipment as soon as possible. *For more details, please refer to the PDF document or feel free to contact us. ★ For inquiries by phone, please call: Osaka Headquarters → TEL: 072-991-1361 Nagoya → TEL: 052-322-1361 Tokyo → TEL: 03-5472-1361 ★ For inquiries by email, please contact: info@fujidenshi.co.jp *When calling or emailing, please mention that you saw this on "Ipros."

● 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.

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.
