1. Pump output
The pump head’s average single pump output is greater than 0.22 grams per milliliter, and the pump output must meet the needs of manufacturers and purchasers.
The shell and the inner cover of the half body cannot be loosened, or there are spies, they need to be closely and completely matched with the outer cover, and the tightness is suitable. After the pump body and the bottle body are tightened, there will be no idling or tooth loss.
The corresponding flat body is tightly matched, and the pump head has no slippage and leakage. You can do a water test to check its leakage.
Fourth, the number of air pressure
The matching bottle is less than or equal to 100 ml, the single pump head is less than 10 times, the matching bottle is larger than 100 ml, the single pump head should be <15 times, and the rebound time of the pump head is less than 3 seconds.
How to check whether the cosmetic pump head is qualified
After the production of the cosmetic pump head is completed, its eligibility must be checked uniformly. The production sample can be put into production after it is qualified, and then put on the market for use. Unqualified products need to be recycled and re-produced. How to check whether the cosmetic pump head is qualified What?
1. Heat and cold resistance test
Choose the bottle matched with the pump head, inject the corresponding volume of water according to the net content of the bottle, and test it in a constant temperature box at 48 degrees for 24 hours. This is a heat resistance test. Place it at minus 5 degrees to 15 degrees for 24 hours in the refrigerator. It is a cold resistance experiment.
2. Appearance inspection
Under natural light, observe the integrity of the pump head at a distance of 30-40cm, including the color, whether the pump head is smooth or not, whether there is obvious damage, cracks, etc.
Three, rigorous inspection
Fill the matching bottle with an appropriate amount of water, tighten the pump head and the bottle body, place them in the vacuum box on the side, and maintain the corresponding atmospheric pressure for five minutes to observe whether there is any water leakage.
The above experiments are more commonly used, and there are pump head rebound experiments, pump output experiments, etc., and the results are good.
