First, according to the emulsion pump raw materials and liquid compatibility selection
Must be able to pass through the Conformance testing.
Second，selection according to the range of Plastic Lotion Pump Bottle output
Before the end product is on the market, there is a consumer survey link, basically there will be a preliminary recommended usage.
According to this amount of use, you can select the emulsion pump
specifications, or pump out the number of integer pump out to the recommended amount of use. GENERAL: recommended usage = (1-2) * Pump output.
For example, if the recommended dosage is 1.0 ml/time, the emulsion pump with 1.0 ml/time can be selected, or the lotion pump with 0.5 ml/time can be selected.
Third, choose according to the final packing form
Have confirmed the packaging capacity, and then according to the size of the packaging capacity, combined with the expected number of use, select emulsion pump specifications. The general use of a package is 100-300 times.
Example 1: 100 ML bottle has been confirmed, the size of the selected lotion pump can be 1.0 ml/times, use about 100 times, or the size of the selected lotion pump can be 0.5 ml/times, use about 200 times.
Example 2: 500 ML bottle has been confirmed, the size of the selected lotion pump can be 2.0 ml/time, use about 250 times, or the size of the selected lotion pump can be 3.5 ml/time, use about 140 times.
Fourth, according to the size of lotion pump and bottle
The lotion pump and the bottle mouth generally take the screw tooth coordination primarily, in the profession has a general standard. General suppliers according to this standard to produce emulsion pump, customers choose emulsion pump according to this specification.
The common diameters are 18mm, 20mm, 22mm, 24mm, 28mm, 33mm and 38mm
Common specifications are 400,410,415.
Fifth, selection according to the viscosity/fluidity characteristics of the stock solution
Specific data on the viscosity/fluidity of the feed solution are available at the end of the product, but are not available for lotion pump manufacturers.
The beaker can usually be filled with a liquid feed, depending on the level of the liquid:
1, the liquid level can be reached in an instant, the liquid level without any traces, all the lotion pumps and derivative pumps can be used, just need to consider the characteristics of the liquid formula to choose the appropriate.
2, the liquid level can quickly reach the level, but the liquid level has a slight build-up marks, spray pump need to verify its spray effect, other lotion pumps and derivative pumps can be used.
3, the liquid level in 1-2 seconds can reach the level, the liquid level has obvious heap marks, need to choose suction, spring force of large lotion pump, high viscosity of the pump preferred choice, followed by the use of vacuum tank/bottle packaging.
4, the liquid surface has obvious stacking marks, can not reach the horizontal state in a short time, high viscosity of the pump also needs to be verified, the priority use of vacuum PET Shampoo Bottle packaging, or choose the CAP packaging.
5, The beaker containing the liquid material is inverted, the liquid material can not be poured out in a short time, can only use vacuum tank, or cover, hose, tank and other forms of packaging.
