The test principle of hot and cold impact test box
Hot and cold impact test box structure and composite material used in the test material, testing in a short time the thermal shrinkage caused by chemical and physical damage, make its can instantly bear very mild hypothermia environment continuously.
Apply to electronic, electrical equipment, vehicles, metals, chemicals, building materials, communication components, defense industry, aerospace industry, electronic chip IC, IT tests of a physical change. Hot and cold impact test cases by high temperature, low temperature area, test area of three parts, adopt unique insulating structure guarantee heat storage effect, is measured with the test perfectly still, switching application of hot and cold air duct into hot and cold gases, completed the high and low temperature cold heat shock test. Independently set high temperature, low temperature, cold and hot impact the function of the three different conditions, the execution of cold and hot shock conditions, choose the function of the three slot or two slot, possess the function of high temperature test chamber. Hot and cold impact test box in appointment start time control in the automatic preheating, ahead of precooling standby, selecting starting position, begin from high or low temperature cycle or temperature shock, set automatic defrost function of cycles.
Blow to exports and back to the detection and control of port sensor, the direction of the wind gate switch time completed within 10 s, cold and hot shock temperature recovery time of completion within 5 min. With temperature line will dc signal output to the temperature recorder, grasp the status of the testing conditions, improve the reliability of detection. Found the abnormal situation in the operation of hot and cold impact test box, screen immediately automatically show the cause of the problem and elimination method, found that the input power is not stable, there are emergency stop device. Hot and cold impact test box is widely used in electronic components, auto components, communication components, automotive components, metal, chemical materials, plastic industry, defense industry, aerospace industry, soldiers, BGA, PCB wrench, electronic chip integrated circuits, semiconductor ceramic and physical change in the polymer materials, the determination of its material of high and low temperature resistance and repeatedly product the chemical and physical damage caused by thermal expansion shrinkage, confirm the product quality, from precision IC to heavy machinery spare parts, both can be used as the basis and the reference of product improvement. The above explanation is the hot and cold impact test chamber, the test principle of hope can help you, if you want to learn more about information about hot and cold impact test chamber, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!

Cut resistance is one of the most critical performance indicators in personal protective equipment (PPE) testing, directly affecting worker safety in high-risk industries such as metal processing, machinery manufacturing, and emergency rescue. The TDM Cut Test Machine GT-KC28 plays a vital role in accurately evaluating the cut resistance of PPE products, including gloves, protective clothing, footwear materials, composite materials, rubber, and industrial textiles.
By adopting high-precision force control systems, intelligent data processing, and stable transmission technology, the GT-KC28 TDM Cut Tester can accurately measure the critical cutting force of materials and ensure excellent repeatability and comparability of test results. Its user-friendly touch-screen operation, comprehensive data storage, USB data export, and built-in thermal printer greatly improve laboratory efficiency and data traceability.
The TDM Cut Test Machine GT-KC28 fully complies with major international and national standards such as ISO 13997, EN 388, ASTM F2992/F2992M, ANSI/ISEA 105, and GB 24541-2022, making it a reliable solution for PPE manufacturers, third-party testing laboratories, and research institutions. Through precise and standardized cut resistance testing, the GT-KC28 helps reduce industrial cutting injuries, supports PPE certification across global markets, and ensures that protective equipment delivers reliable safety performance in real-world applications.
