Something important of test------Scrap test of Raw Materials!!!
● About Circuit board
1. High and low temperature test:
High temperature 80 ° C, low temperature and strong cold, power running test for 48 hours, and test signal reception. After the test is finished, the circuit board is placed at normal temperature to restore the temperature of the circuit board to normal, and then exchanged for high and low temperature environment for 48 hours.

2. Load test:
After the high and low temperature test is finished, the circuit board is mounted on the vertical load frame for 30 days, and the operation status is recorded every day. After the test, the test results are summarized and analyzed.

3. Constant resistance to rebound:
Conduct a continuous resistance rebound test on the physical door to see if there is any running position or other abnormal conditions.

4. Infrared resistance rebound:
Install a set of infrared rays on the physical door, perform infrared resistance and rebound test, check the operation status.


● About Motor Shaft Sleeve & 12-tooth sprocket:
1. Wear test:
Match various types of motors, continue to run the test for 1 month, record the number of runs, observe the wear of the motor and bushing at the same time after the test, and judge the results.


● About silent rubber of metal base:
1. High and low temperature test:
A number of rubber mats were randomly selected and tested for high and low temperature for 72 hours. After the test, the rubber mats were observed. If there was no cracking, the temperature was restored and the high and low temperature environment was exchanged for 72 hours.

2. Outdoor aging :
Place the rubber mat outdoors for one month, and check the material changes after the wind, sun and rain.

3. Actual use:
After the high and low temperature and outdoor aging test is finished, install the bottom plate, the actual operation test of the upper load frame, record the use situation, remove it after 30 days to check the wear and cracking situation, and summarize.
