What Are The Functional Tests And Composition Principles Of Cosmetic Pump Heads?

Cosmetic pump heads have to go through many aspects of inspection before they leave the factory. For its functional inspection, it also includes many aspects. Let's take a look at the functional inspection of the pump head.

1. Pump output

The average single pump output of the pump head is greater than 0.22 grams per milliliter, and the pump output must meet the needs of manufacturers and buyers.

2. Compatibility

The half-body shell and the inner cover cannot be loosened, or if there are spies, it needs to be tightly and completely matched with the outer cover, and the tightness is appropriate. After the pump body and the bottle body are tightened, there will be no idling, tooth loss, etc.

3. Tightness

The corresponding flat body fits tightly, and the pump head does not slip and leak, so a water test can be done to check its water leakage.

4. Compression times

Matching bottle ≤ 100 ml, single pump head < 10 times, matching bottle larger than 100 ml, single pump head should be < 15 times, and the rebound time of the pump head is preferably less than 3 seconds.

A kind of foundation on the market can be divided into air cushion or bottled liquid foundation, so there will be differences in the seal.

Regarding the lotion pump, its specifications generally range from 16 to 38 milliliters, and the water output is 0.28 milliliters to 3.1 milliliters each time.
