Application
1. Consumer Electronics: With the widespread adoption of electronic products such as smarts, tablets, and wearable devices, the bending performance of their screens, casings, and other components in cold environments has become a key concern for users. This testing machine allows manufacturers to evaluate product durability under extreme climatic conditions, ensuring that the user experience remains unaffected.
2. Automotive and Aerospace: In the aerospace industry, the casings, wings, and other structural components of aircraft and rockets need to withstand high-altitude low temperatures and complex aerodynamic loads; in the automotive industry, with the rise of electric and smart vehicles, the low-temperature resistance and bending strength of battery packs and body frames are equally important. The vertical low-temperature bending test machine provides strong support for material research and product design in these fields.
3. Building Materials and Piping Systems: In extremely cold regions, the thermal insulation performance of building exterior walls and the antifreeze performance of piping systems directly affect residents' quality of life and public safety. This testing machine can simulate extreme low-temperature conditions to test the crack resistance, flexibility, and overall structural stability of materials.
4. New Energy and Environmental Protection Technologies: In new energy fields such as wind and solar power, the low-temperature resistance and wind pressure bending strength of key components such as wind turbine blades and photovoltaic panels directly affect the power generation efficiency and service life of the equipment. The vertical low-temperature bending test machine provides a reliable testing method for technological innovation and product optimization in these fields.

Accessoriess
Refrigeration System: Utilizing advanced refrigeration technologies such as liquid circulation, mechanical compression refrigeration, or a combination of both, the system can quickly lower the temperature inside the test chamber to the set value and maintain a stable low-temperature environment. The efficiency and stability of the refrigeration system directly affect the accuracy of the test results.
Temperature Control System: Through high-precision temperature sensors and PID control algorithms, precise control of the temperature inside the test chamber is achieved. Users can set any temperature point according to test requirements, and the temperature control system automatically adjusts the cooling power to maintain a constant temperature inside the chamber, with an error range typically within ±1°C.
Mechanical Transmission System: Includes a motor, reducer, transmission shaft, and bending mechanism, responsible for driving the sample to perform periodic bending movements. The design of the transmission system must consider adjustable speed, uniform force distribution, and long-term operational stability to ensure consistency and reliability during the testing process.
Sample Fixture: Designed and customized according to the shape, size, and material of the sample, used to fix the sample and maintain its correct position and posture during the bending process. The design of the fixture must consider ease of operation, secure sample fixation, and avoiding unnecessary damage to the sample.
Data Acquisition and Processing System: Equipped with high-precision sensors and data acquisition cards, it can monitor and record key parameters such as temperature, bending cycles, bending angle, and sample deformation in real time during the test. Simultaneously, the accompanying software system can process and analyze the data, generating intuitive charts and reports to facilitate user evaluation of the test results.
