87L Air to Air 3 ozone Thermal Shock Test Chamber for Metal Plastics Rubber Electronic Tester
Application of cold and thermal shock machine:
Temperature shock chamber is used to test the capability of material structure or composite materials to withstand the continuous environmental changes between extremely high temperature and low temperature during a short period, and therefore understand the chemical changes or physical damages caused by expansion from heat and contraction from cold in the shortest possible time. It is applicable to metals, plastic, rubber, electronics amongst other materials. The test result can be used as a reference or basis for product improvement.
