WBE-LR3D Large three-slot thermal shock test chamber

The thermal shock test machine is used to test the chemical structure changes caused by thermal expansion and contraction in the shortest time by testing the material structure or composite material in a transient environment of extremely high temperature and very low temperature. Or physical damage. Applicable objects include automotive electronics / components, LED / LCD / PDP display lighting, new energy / electronic components / electrical appliances, plastic / rubber / film, research / quality inspection / college / medical equipment, PCB / FPC / HDI / MPCB / IC



※ Fully automatic PID control with high precision and saving 30% power,

※ Three boxes of equipment are divided into three parts: high temperature zone, low temperature zone and test zone. The test products are placed in the test zone. The temperature of the high temperature zone or the low temperature zone is impacted into the test zone during impact, and the test product is static.

※ It adopts touch-type graphic control operation interface, which is easy to operate.

※ Impact mode Apply the air path switching method to introduce the temperature into the test area and do the thermal shock test.

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

※ The system can be used for automatic cycle or manual selective shock and can set the three-zone impact and cold flushing.

※ Cooling and adopting binary refrigeration system, the cooling effect is fast, and the cooling method is water-cooled.

※ Three boxes can test the impact normal temperature,

※ High and low temperature conversion time: within 10 seconds (other requirements are agreed)

※ Execution meets the standards and test methods: GJB150.5 temperature impact test; GJB360.7 temperature impact test; GB/2423.22 temperature impact test
