Cheap Dispenser FAQ
The most common problem encountered by the glue dispenser is the valve problem. The following are effective methods to solve the problems that often occur when the glue valve is used.
Valve dripping This situation often occurs after the valve is closed. 95% of these cases are due to the use of needles that are too small in diameter.
A needle that is too small can interfere with fluid flow and cause back pressure, which can result in dripping shortly after the valve is closed. A needle that is too small will also affect the bubble-exhausting action of the valve when it starts to use. This problem can be solved simply by replacing the needle with a larger one. The tapered angled needle generates the least back pressure and provides the smoothest fluid flow. The air in the liquid will drip after the valve is closed. It is best to remove the air in the liquid in advance, or use a glue that is not easy to contain air bubbles. Or use the glue after centrifuging and defoaming.
