The size of injection needle tip is the direct reason for de

The size of the dispensing needle is generally considered to be controlled by the pressure. In fact, part of the reason is determined by the thickness of the bottom injection needle. The size of the needle is one of the factors affecting the amount of dispensing during the injection. Whether the straight needle or the curved needle, there is a problem that the size of the dispensing needle affects the amount of dispensing. This time, the diameter of the injection needle is explained by the distance of the 45 degree curved needle. This is one of the direct reasons for the uneven amount of gel injection.

Instructions for curved needles
 
45 degree bending needle is used in some industry applications which need special position to coat, so it is also called bending needle. The middle end of this needle is bending needle, which can flow out from the tip of injection needle along the shape. It can be added to the dispensing valve or dispensing needle barrel to control the bending out of glue, such as packaging box sealing or circuit board coating needle filling. Full glue quantity control is aimed at fine seam coating at the same time. The uniform control of glue thickness is one of the criteria to measure whether it is suitable for these precise industries. The deflection of the path is more suitable for application by adjusting the injection with this 45-degree bending needle. The size of the needle tip is mainly determined by the specifications.

The size of needle is between 144G and 34G. The larger the number of needle specifications, the smaller the structure. Therefore, the smaller the injection needle tip at the bottom of the needle with high specifications, the higher the precision of the glue output. The bending needle is based on this principle to select the correct specifications. The common specifications of 45-degree bending needle are about 20G. The glue amount can be uniformly coated mainly because of the bending characteristics. The rationality of outflow used for sealing and adhesives is reasonable. The application of injection needle tip of this specification meets most industrial applications. The demand for adhesives for packaging box sealing and circuit board coating is uniform but not excessive. In addition to adjusting the pressure, the selection of specifications will be a direct factor affecting the control of the thickness of injection needle tip.

There is a need for the rigidity of the bending needle in the application of packaging box sealing and circuit board coating. In the selection of specifications, different types of adhesive coating should be changed according to the required coating accuracy, so that the thickness of the injection needle nozzle can be controlled and the application of dispensing is relatively comprehensive.
