The representative heating observation IR imaging furnace from Mikyo Manufacturing has been equipped with a digital violet laser microscope. It enables clear microscopic observation in ultra-high temperature environments of up to 1800°C. Compared to conventional models, the resolution and brightness have improved by about two times*, allowing for observations with high magnification and high contrast. Please utilize it for research on the behavior of fine structures and material development under high temperatures in steel, non-ferrous metals, ceramics, secondary batteries, and more. *Compared to our conventional model "VL2000DX-SVF17SP" ◆ Key Points ◆ - High-resolution in-situ observation Obtaining high-resolution images under ultra-high temperatures - Realization of diverse observation conditions Rapid heating and rapid cooling up to 1800°C - Excellent operability and controllability High-speed image acquisition accurately linked to temperature By using the optional load mechanism module "SVF12FTC," observations can be conducted under stress loading (up to 5kN) at high temperatures. For more details, please contact us.

The "OCT-equipped heating observation imaging furnace," which allows for direct observation of internal structural changes at high temperatures, has contributed to the study of changes in the internal structure of ceramics. It is a compact device utilizing a focused heating method and equipped with OCT (Optical Coherence Tomography) for internal observation. ◆ Key Points ◆ - Internal structure observation at high temperatures In-situ observation up to 1800°C - Understanding weight and thermal changes Clarifying the relationship between internal changes and temperature/weight changes - Excellent operability and controllability Data acquisition combining weight changes with temperature OCT is a technology that uses infrared laser light to visualize the interior of materials. It can be applied to materials such as ceramics and resins that allow infrared light to pass through. For more details, please refer to the catalog or contact us.

At Yokura Manufacturing, we manufacture equipment necessary for evaluating the durability and safety of battery materials and components for next-generation batteries, including all-solid-state batteries. We solve challenges in development and manufacturing with a custom-made approach. ◆ Small Vacuum Heat Seal Device for Glove Box This is a chamber-type vacuum heat seal device that thermally bonds cells, such as laminated (pouch-type) lithium-ion batteries, through heating and pressurization. ◆ Heating Device for All-Solid-State Batteries Compatible with Glove Box IR-HP/GB Depending on the material screening temperature characteristics, it heats and evaluates up to four solid-state batteries simultaneously without exposure to the atmosphere.
