Plastic dispensing needle diameter,

Plastic dispensing needle diameter,

The dispensing needle is the metal needle of the metal needle at the top of the dispensing syringe. The high-precision dispensing needle is the dispensing needle with higher and stricter requirements for dispensing accuracy,

The dispensing needle is also called the dispensing needle tube. When it is added to the glue valve or needle barrel to align the dispensing or dispensing links, it needs to be calibrated in advance. The calibration is to improve the accuracy of needle alignment. It should be used for uniform and stable dispensing or dispensing. Whether it is a straight plastic needle, a stainless steel dispensing needle, or even a special curved dispensing needle it should also be calibrated, The coordinate position alignment after calibration is high, and the precision control effect is improved by using many electronic product sealing glue or packaging box sealing and circuit board coating adhesive

Plastic dispensing needle diameter,

Size of dispensing machine needle. Generally, the needle with the inner diameter of about 1 / 2 of the dispensing point diameter shall be selected. In the dispensing process, the dispensing needle shall be selected according to the product size.

The distance between the needle and the working face. To grasp the dispensing distance, you should know that different dispensing machines use different needles, and each needle has a specific stop. Therefore, before each operation, the distance between the needle and the working surface, i.e. z-axis height calibration, should be calibrated.

As a reminder, the glue must not have bubbles. A small bubble will cause many products to have no glue. When replacing the rubber hose in the middle of each time, the air at the connection shall be emptied to prevent empty beating.
