The pump is a mechanical device that releases the contents in a predetermined form and has sealing properties on the principle of generating a vacuum through pressure. After decades of development, pumps have penetrated into every aspect of daily life. And in the function, appearance, practicality and other aspects have been greatly improved. It has developed into various types of products such as lotion pumpsfoam pumps, industrial pumps, and agricultural pumps that can meet the needs of different people.

    We know that each product must go through inspection and quality control procedures before it is put into the market so that such products can enter the market and flow into the hands of consumers. Here, the inspection and quality control of the products are to be experienced.

    Tightness: Fill the bottle with colored water (or customer liquid) according to the product specification, use the corresponding torque to match the pump head with the bottle according to the different calibers, press and lock the state, place it horizontally, and vacuum the test - 0.03~-0.06MPa /5min (different customer requirements are inconsistent). After the test, there is no leakage at the joint between the bottle and the screw, the joint between the bottle body and the cap, and the pressure head.

   After the indenter is matched with the main column, the separation force between the indenter and the main column should generally be able to bear the weight of the entire package. The general parameters are not less than 2Kgf.

   Air pressure time/first spray time. Refers to the total number of compressions by the consumer from opening the handpiece to the first discharge of liquid. The common standard is 6-10 times.

   Pump output: Refers to the volume of liquid pumped by the consumer each time the emulsification pump is used. Usually, the tolerance of the pump output is about ±10% of the theoretical design value.

   The opening torque between the indenter and the lock cover is 3-10Kgf

   Drop test: Match with the corresponding bottle, fill it with a standard weight of liquid (or water), drop it vertically once from a height of 0.8-1.2 meters, the bottle touches the ground first, it is qualified if it meets the following conditions, it is not damaged or loose. (Note: This test is only carried out for the products with changed materials or formulas, and new molds are mass-produced for the first time).

   Pump feel: good rebound, no stuck, rebound time ≤ 1.5 seconds, press ≥ 2000 times fatigue test, the rebound must be normal.

   The tightness of the straw and the barrel should be moderate, not too loose (easy to fall off), nor too tight (easy to explode). General parameters not less than 0.5Kgf can be qualified (products with different hose specifications need to be re-evaluated).

   The thread and the bottle mouth fit smoothly without slipping, blocking, or crooked.

   Yuyao Feifan Commodity Factory is an Edge Booster Spray Bottle manufacturer, mainly producing various cosmetic packaging supplies such as CONTIN-U-SPRAY BottleFoam Pump, etc.
