It is used in industries such as electronics, auto parts, and plastics to test the repeated impact of various materials on high and low temperatures, and has been tested
Chemical changes or physical damage caused by thermal expansion and contraction of the product.
This equipment is divided into three parts: the high-temperature zone, the low-temperature zone, and the testing zone. It adopts a unique heat insulation structure and cold storage effect. It will be tested during the test
When the object is completely stationary, it should be introduced into the test sample by switching between cold and hot air paths for cold and hot shock testing.
It has the function of independently setting three different conditions: high temperature, low temperature and thermal shock, and when performing thermal shock conditions, it is equipped with
The functions of the high and low temperature testing machine. (See Figures 1 and 3
