1、 Product details:< Cold and hot shock testing machine is used to test the degree to which material structures or composite materials can withstand continuous environments of extremely High and low temperatures in an instant, in order to test the chemical changes or physical damage caused by thermal expansion and contraction in a short period of time. The applicable objects include materials such as metal, plastic, rubber, electronics, etc., which can be used as a basis or reference for product improvement< 2. Product Features:< The two box equipment is divided into two parts: high temperature zone and low temperature zone. The test products are placed in a basket, During impact, the basket will move the test product into a high or low temperature zone for balancing, and the test product is dynamic.

Adopting a touch based graphical control interface, the operation is simple.

The impact method applies the air path switching method to import the temperature into the testing area for conducting cold and hot impact tests.

When subjected to high or low temperature impact, the maximum duration can reach 999H, and the maximum cycle time can reach 9999 times.

The system can be used as an automatic loop engine or a manual selective impact.

The cooling system adopts a binary freezing system, which has a fast cooling effect and is water-cooled.

Cannot test impact at room temperature
