The cold and hot impact testing machine is also known as the high and low temperature impact testing chamber, and Taiwan is called the cold and hot impact testing machine, which is used to test the endurance of the material structure or composite material under the continuous environment of extremely high temperature and extremely low temperature in an instant, so as to test the chemical change or physical damage caused by thermal expansion and contraction in the shortest time. The test chamber is divided into two parts: high temperature zone and low temperature zone. The test sample is placed in the mobile basket. The unique heat storage and cold storage structure is adopted. The cylinder drives the basket to move up and down in the cold and hot bath to complete the cold and hot temperature impact test; Applicable objects include metal, plastic, rubber, electronics Such materials can be used as the basis or reference for product improvement.
