What should I do before leaving the factory?

It is to test the temperature and duration of his fever.

Before leaving the factory, we will generally be confident that each of its quality inspections will only be able to be carried out externally if the quality inspection is passed.

The coil type is safer than the electrode type, and the electrode type can touch the two cylinders inside, one long and one short, and the coil type is often a big flat thing. At present, the state expressly prohibits the production and sales of electrode electric heaters, but there are still many manufacturers and stores in the illegal production and sales.

The principle of hand warmer is actually a hot water bottle, which just replaces the water with oil, seals it, and directly heats it with electricity. It's impossible to test all of these things before they leave the factory, only random inspections. It is nothing more than checking for oil leakage, doing a pressure test and charging test.

The inspection to be done before leaving the factory is carried out in accordance with the standards.

What should I do before the charging energy treasure leaves the factory? This should specifically check the information in this area, and learn more about some aspects of the detection.

When I charge a hand warmer, I will definitely check the quality of the problem. To prevent this distilled water from happening during the charging process**, this is all tested.

Before charging, all aspects of quality inspection must be carried out, and safety needs to be ensured.

Hello, this charging hand warmer needs to be charged for testing, is the material safe?

How long does it last?

These are the things that need to be done.

The rechargeable hand warmer must do a safety test function before leaving the factory, you can take a look, or whether there is a water leak or something like that.

Before leaving the factory, we must do explosion-proof, anti-pressure and overpressure tests, and these functions will be tested.

The function keys to be done before the charging wrench is guaranteed to leave the factory is whether there is leakage and whether it can be charged.

Before leaving the factory, the charging hand warmer should be tested to see if there is a problem with the circuit, and whether there is a quality problem with the heating element and whether there is a problem with the charging cable.

Before leaving the factory, the charging hand warmer must be tested for charging test and safety test.

For example, the stability of the current. And there is no phenomenon of some leakage electricity. The main thing is to ensure the use, reliability.

Before leaving the factory, the entire hand warmer circuit should be tested, and at the same time whether there is leakage, and there is no problem before leaving the factory.
