How to control the precision of high precision dispensing needle

The top of the curved dispensing needle is curved, so it is called dispensing curved needle. It is a kind of high-precision dispensing needle. The curved dispensing needle is made by using the precision bending process, which will not cause the problem of needle glue curing due to bending. It is suitable for use in special industries, such as electronic industry, auto parts, medical instruments, etc. these industries have different requirements for dispensing volume, which need to be customized according to the actual needs of non-standard needle manufacturers. Can the dispensing accuracy be controlled by using this high-precision dispensing needle?

Brief introduction of curved dispensing needle

Because the top of the curved dispensing needle is curved, the dispensing work of the curved dispensing needle is different from that of other high-precision dispensing needles. The dispensing accuracy of the needle is related to the dispensing amount of the needle. If the dispensing amount of the curved dispensing needle used is not suitable for the product requirements, it will affect the dispensing accuracy of the curved dispensing needle, and the probability of needle glue solidification will also increase. Therefore, when selecting the curved dispensing needle by non-standard needle manufacturers, it is best to select the appropriate inner diameter, bending angle and bending dispensing needle according to the dispensing requirements, Avoid improper dispensing and affecting the dispensing accuracy.

The needle specification and bending angle are related to the accuracy

The selection of the needle angle can be based on the actual size of the needle during the dispensing process. As mentioned earlier, this high-precision dispensing needle will not affect the smooth dispensing due to the bending of the needle, so there is rarely the phenomenon of curing and blocking of the needle glue. However, it is best to understand the use problems before use to avoid the curing of the glue on the needle for some reasons, which will not only affect the uneven dispensing volume, but also have some impact on the dispensing work. So what should I do when the glue of the curved dispensing needle is solidified and blocked?

Method for solving curing of needle glue

Generally, the high-precision dispensing needle is made of plastic and stainless steel. When the glue of the bending dispensing needle made of plastic solidifies, it can be replaced and used again. If the glue of the needle solidifies when the stainless steel bending dispensing needle is used, the glue can be melted with a heater to ensure the dispensing accuracy, At present, there are few plastic bending dispensing needles in non-standard needle manufacturers.
