The temperature cycling test at a range of -40℃ to 125℃ showed no failure. The salt spray test lasted for 1000 hours and still maintained a contact resistance of less than 50mΩ; This is used for the door micro-switch assembly to achieve a 0.1-second-level anti-collision feedback; The door switch supply has cumulatively supported the production of 1.2 million vehicles.

There was no false judgment in the detection of the water tank position of the coffee machine, ensuring the reliability of the automatic power-off safety mechanism; the monthly output of 500,000 pieces had a yield rate of 99.98%, and it met the zero supply interruption requirement in conjunction with the DeLong JIT production mode; it passed the 500,000 times fatigue test by DeLong (far exceeding the industry standard of 300,000 times), meeting the usage frequency of over 300 times per day.

In the safety test of thesoybean milk machine body, a rapid power-off within 0.01 seconds is achieved, perfectly matching the anti-overfill patent technology of Joyoung； With a continuous steam test at 120℃ (industry standard is 100℃)， the lifespan exceeds 50，000 times； Maintaining a stable supply of 300，000 units per month！
