2. Production process

lotion pump  production process

Most of the parts of the pump head are mainly made of PE, PP, LDPE and other plastic materials, and are molded by injection molding. Among them, glass beads, springs, gaskets and other accessories are generally purchased from outside. The main components of the pump head can be applied to electroplating, anodized aluminum cover, spraying, injection molding color, etc. Graphics and texts can be printed on the nozzle surface of the pump head and the surface of the braces, and can be processed by printing processes such as bronzing/silver, silk screen printing, and pad printing.

2. Working principle
Manually press down the dynamic pressure handle, the volume in the spring chamber decreases, the pressure increases, the liquid enters the nozzle chamber through the hole of the valve core, and then the liquid is sprayed out through the nozzle, then release the pressure handle, and the pressure in the spring chamber The volume increases to form negative pressure, the ball opens under the action of negative pressure, and the liquid in the bottle enters the spring cavity. At this time, there is a certain amount of liquid in the valve body. When the handle is pressed again, the liquid stored in the valve body will be Punch up and spray out through the nozzle;
