- Creating free and innovative development in a lab atelier - In Italy, small companies produce remarkably high-precision machinery and export it in large quantities overseas. We want to incorporate the "free and open atmosphere," which is the source of this creativity, into our manufacturing site as we aim to be a small to medium-sized enterprise in the 21st century... From this idea, the headquarters of Yokekura Seisakusho was constructed with the aspiration of an Italian lab atelier (experimental workshop). As a result, a variety of innovative high-function testing equipment is being developed one after another. ≪Features of Yokekura Seisakusho≫ Since its establishment in 1980, we have pursued technology as a specialized manufacturer focused on testing machines, striving to provide optimal products and services. We respond to the needs of various customers across different industries, producing material testing machines and custom testing machines, utilizing the know-how we have cultivated to address all challenges, from cutting-edge research to everyday testing. During the manufacturing of equipment, the software, electrical, and mechanical departments always collaborate and share opinions. We provide feedback on the field's requests to meet specific conditions and strive to offer the optimal measuring instruments as a whole department.

○ High-Temperature Atmosphere Tensile Testing Machine CATY-T3V A universal testing machine capable of testing at a maximum temperature of 1500°C under various atmospheres (vacuum, gas flow). ○ High-Pressure Atmosphere Friction Testing Machine CATY-FSD A testing machine capable of conducting friction tests at a maximum speed of 3000 rpm and a maximum load of 5 kN inside a pressure vessel.

Using the IR series high-temperature observation furnace for demonstrations: <<Heating/Atmosphere Control/Oxidation Experiments>> Metals/Solders/Ceramics/Solder/Glass, etc.

This measurement allows you to experience high-temperature observation using the demo unit of our IR series that we sell. The furnace of the IR series has a sealed structure, allowing it to operate in an environment where atmosphere manipulation is performed. In the case of the IR-18SP, it can reach a maximum temperature of 1700°C. You can check videos of actual experiments and test programs to capture changes in the test subjects in real-time. Please note that since the equipment used is a demo unit, we may not be able to accommodate all requests, so please contact us for details. The thermal capacity of the test specimen may cause fluctuations. ▮ Equipment Specifications Heating Temperature: MAX 1700°C Heating Rate: 50°C/sec Temperature Accuracy: Within ±1°C Atmosphere: In air, in vacuum, gas flow Sample Size: Please consult us Observation Magnification: Macro to approximately 1000x ▮ High-Temperature Observation Examples Metals: Melting/Phase transition/Powder metallurgy processes Filler materials: Melting behavior Ceramics: Sintering/Micro-crack generation Solder: Melting/Wettability Glass: Melting/Recrystallization

Because we have the know-how for manufacturing test equipment, we can fulfill custom test requests as desired. We receive many production requests mainly for material/product development, research, and testing.

▼Features of Yonekura's Custom Test Machines▼ ≪Accumulated Know-How≫ Since our establishment in 1980, we have been continuously manufacturing test machines, accumulating know-how and demonstrating technical capabilities and achievements by creating one-of-a-kind original test machines that do not exist anywhere else in the world. ≪Designed to Meet Customization Requests≫ Our company conducts design and software development in-house. While we design products according to established specifications, we can customize aspects that can be tailored to other operational actions and usage methods. ≪User-Friendly with In-House Developed Software≫ We also design electrical circuits and software in-house, and if requested, we can combine technologies such as data processing and upper-level transmission to further enhance usability for our customers. ▮Yonekura's Guiding Principles We value the following principles in creating our test machines: - We plan to continuously improve our knowledge and abilities, pursuing customer demands with the results we achieve. - We do not settle for experience and the status quo; we prioritize user feedback, boldly challenge ourselves, and contribute to a safe society by planning and continuing to develop products that can be communicated to the world. - As a manufacturer of material testing machines, we will sincerely work to earn even greater trust from everyone.

Minimize work inside the glove box ◎ Screening of solid electrolyte materials / Impedance evaluation by temperature characteristics ◎ Multiple uniform, short time, and accurate test evaluation

Temperature range: RT ±20~1200℃ Temperature control accuracy: ±1℃ (relative to temperature protocol) Heating speed: MAX 300℃/min Coin cell holder: 4 slots (can heat/measure under the same conditions) Structure: Heating while electrodes are attached to the top and bottom of the coin cell Coin cell diameter: Φ20~Φ8mm Heating method: Light concentration heating 【Heating test procedure】Set the sample in the holder → Seal inside the quartz tube → Take it outside as is → Just set it in the heating device.

Utilizing the know-how of custom testing machines, we support testing and research with material testing machines such as [impact/fatigue durability/tensile/torsion testing machines, etc.].
