Thermal - Cold Cycle Testing Machine

The Thermal-Cold Cycle Testing Machine is a professional equipment used for high and low-temperature reliability testing. It is primarily used in fields such as electronics, electrical engineering, automotive, and aerospace, to test the performance of materials and components under extreme temperature conditions. It conforms to GB/T2423.1.2.3 standards and supports three test modes: high temperature, low temperature, and thermal shock. Rapid temperature switching can be achieved through a two-chamber or three-chamber structure.

Applications

1. Electronics and Electrical Engineering: Testing the temperature stability of chips, batteries, etc., to meet industry standards;

2. Automotive Industry: Verifying the temperature resistance of automotive electronics and body materials;

3. Materials Science: Screening the temperature tolerance of plastics and composite materials to support material selection;

4. Aerospace/Defense Industry: Adapting to extreme temperature change scenarios to ensure stable equipment operation;

5. Medical/Construction Materials: Verifying the temperature durability of medical equipment and building materials to meet compliance requirements.

Standards

BS 7291: Compliant for thermal cycling tests on thermoplastic pipe systems (1769 Series with pressure chamber).

Adaptive Certification: Configurable to meet ISO, ASTM, and EN standards upon request.

Test Procedures

1. Pre-test Preparation

Check that the instrument's power supply and cooling/heating systems are functioning correctly, replenish the circulating medium, clean any impurities from the test chamber, and calibrate the temperature sensor.

2. Sample Preparation and Installation

Cut the sample according to testing requirements, record the sample's basic information, place the sample smoothly into the test chamber, avoiding stacking, and ensure the sample does not touch the chamber walls.

3. Parameter Settings

Select the test mode via the control panel, set the high and low temperature thresholds, constant temperature duration, number of cycles, and heating/cooling rate. Save the parameters after confirming their accuracy.

4. Starting the Test

Close the test chamber door, press the start button, and the instrument will automatically run according to the set parameters, monitoring the panel temperature and operating status in real time.

5. Test Monitoring

During operation, observe the instrument for any abnormalities, record changes in the sample's state during the temperature cycling process, and prevent sudden malfunctions from affecting the test.

6. Test Completion and Cleaning

After reaching the set number of cycles, the instrument will automatically shut down. After the chamber temperature returns to room temperature, open the chamber door, remove the sample and record the test results, clean the test chamber, turn off the instrument power, and organize the test data.
