▼Automation Points for Reading at Yonezawa Manufacturing▼ ▮Immediate Digitalization of Test Results By introducing software, handwritten or manually entered test results can be automatically read, allowing data to be imported from the testing machine*. Recording for each test specimen becomes easier, and real-time graphing is also possible. *Please confirm that there is no external output such as voltage from the testing machine. ▮Customization of Recorded Data and Input Items Management data can be customized according to your requirements. You can increase the number of optional input items and confirmation checks, allowing for better management of required data on the computer screen. Test reports utilizing this data can be issued immediately, and it is also possible to change the input and output items according to other information that needs to be output. ▮Simultaneous Automatic Recording of Other Tests and Conditions Temperature and humidity during testing, as well as outputs from digital gauges and calipers, can be recorded on the computer simultaneously, eliminating the hassle of "checking and recording." With this feature, you can simply press the start button for the test, and other information can be easily recorded, contributing to a reduction in labor.

This is a shock testing machine for metallic materials, designed to achieve a stable structure with sufficient rigidity, ensuring reliable and reproducible test results. The "semi-automatic" feature, which automatically lifts and releases the hammer, reduces the labor and time required for operation and contributes to safety. By combining it with the data processing device we provide, it can automatically import and save data (such as angle and absorbed energy) to a PC, further supporting compliance systems. It is used not only for testing but also for research. If you have any questions, please feel free to contact us. ▼ Instrumentation Software [CHARPAC]* Optional ▼ The Charpy impact testing machine comes with instrumentation software that allows users to view results in graphs and numerical values instead of just visually. The software is developed in-house and can be customized to meet customer needs for ease of use.

▼Key Points▼ 1. Insights for investigating and clarifying the causes of issues during the heating process can be obtained. 2. Useful for analyzing the mechanisms of material reactions and behaviors at high temperatures. 3. Changes under various temperature controls, such as rapid heating and rapid cooling, can be confirmed. ▮What is the IR Series? It is a furnace that can heat by efficiently focusing infrared rays emitted from a near-infrared lamp, which are reflected by the gold plating on the furnace walls, onto the heating area in the center of the furnace. (For details, please visit the IR image furnace feature page.) ▮Examples of Test Subjects Metals / Filler materials / Ceramics / Solder / Glass, etc. ▮Examples of Conducted Tests Heating / Atmosphere manipulation / Oxidation experiments, etc. ▮Examples of Utilization High-temperature heat treatment / Video confirmation of behavior during firing (microscopic level) For research and development, troubleshooting, and yield improvement. *Tests involving heating only are also accepted. The experimental temperature may vary depending on the heat capacity of the test specimen.* *There may be variations depending on sample size and test conditions.* Other experimental examples are also available on the official YouTube channel!

The "CATY-T3H SYSTEM" is a tabletop high-temperature tensile observation device that allows for thermal fatigue testing while observing the condition of the sample surface in real-time. It can be operated easily and supports high-temperature and high-speed heating. The adoption of a dual-swing crosshead ensures that the sample's position remains centered, even with expansion and contraction, minimizing any displacement of the observation point. By combining it with optional units, it can also accommodate tests such as bending observation. 【Features】 ■ Capable of high-temperature and high-speed heating up to 1500°C * However, this depends on the shape and thermal capacity of the sample. ■ Suitable for testing not only metallic materials but also composite materials of surface-mounted components ■ Enables stress measurement, low-cycle fatigue testing, and creep testing in gas flow or vacuum conditions ■ Realizes combined testing of thermal fatigue under stress and real-time observation * For more details, please refer to the documentation. Feel free to contact us with any inquiries.
