What is the reason why the emulsion pump can't rebound when pressed

In order to avoid this kind of situation, in the production process, we should first check whether the spring length is standard, the difference is a thousand miles, the effect of length on the piston can  be ignored, if it is short, it will cause the return stroke of the piston is  in place, directly cause the spring back  to work  rebound slowly after pressing down the head.

Secondly, check whether the thickness of the piston fits the body. In the movement of the piston, any trace of gap will cause weak suction,  press the head to press the discharge body. Because the plastic has the property of thermal expansion  cold contraction, the normal piston is very important to ensure the quality of the emulsion pump.

Finally, we will analyze the body. In view of the plastic's extensibility, if the injection is  done properly during the injection molding, a thin layer of the body will be cut off, resulting in uneven inner wall. The gap will inevitably be left in the process of piston stamping, resulting in no discharge.

Do you know what material is used for emulsion pump? Finally, let's analyze the body. In view of the scalability of plastics, improper injection will cause a thin layer of the thin layer during the injection molding process, resulting in uneven inner wall. Inevitably, there will be gaps in the process of piston stamping, which will lead to no material discharge.

Do you know what material is used for the emulsion pump? The main material of the emulsion bottle is acrylic, glass  metal,  the outer packing is mainly for the pursuit of fine  high grade. There are two forms of emulsion bottle on the cover, which are mainly acrylic, glass  metal,  the outer packaging is mainly for refined  high-grade. There are two forms of emulsion bottle on the cap. The common emulsion pump is covered by the emulsion pump,  is covered by the squeezing emulsion pump. It can effectively control the extrusion amount of the emulsion,  is well received by the market. The popularization rate is high,  the relative cost is higher. Another is the ordinary bottle cap packaging, but the bottle mouth will often set up very small, which also can effectively control the amount of emulsion 3, but there is no emulsion pump convenient.
