Used in industries such as electronics, automotive parts, plastics, etc., to test the repeated impact tests of various materials on high and low temperatures, and to achieve
Chemical changes or physical injuries caused by thermal expansion and contraction of products.
This equipment is divided into three parts: high temperature zone, low temperature zone, and testing zone. It adopts a unique heat insulation structure and cold storage effect, which is to be tested during testing
The object is completely stationary, and the cold and hot air path switching method should be applied to import the sample for cold and hot impact testing.
It can independently set three different conditions: high temperature, low temperature, and cold/hot shock, and has the ability to perform cold/hot shock conditions
The functions of high and low temperature testing machines. (See Figures 1 and 3)

Features:
Electronic and electrical components, metals, chemical materials, automation components, communication components, national defense industry, aerospace industry
An ideal testing tool for physical changes in BGA, PCB substrates, electronic chip ICs, semiconductor ceramics, and polymer materials.
Adopting a large human-machine touch dialogue LCD human-machine interface controller, it is easy to operate, easy to learn, stable and reliable.
The impact method adopts a style switching method, which imports the cold and hot temperatures into the testing area to achieve the purpose of cold and hot impact testing.
The impact time is 0.1 to 999.9 hours, and the cycle time is 1 to 9999 times, which can be set.
Can set the number of cycles and defrosting times for automatic (manual) defrosting.
Display and curve of operating status, explanation and troubleshooting methods for displaying abnormalities and fault points.
The European and American original high-efficiency overlapping compression refrigeration unit is an equipment with low operating noise and energy saving.
Adopting PID automatic calculation control function, the temperature control accuracy is high.
It can be used for automatic loop impact or manual selective impact, and can choose two groove or three groove type as well as cold and hot impact.
Can independently serve as a high-temperature or low-temperature box, with one machine for three purposes.
Adopting green and environmentally friendly (HFC) imported DuPont refrigerants R404 and R23 with zero ozone coefficient.
Instant impact curve (see Figure 2).
