The long dispensing needle is a kind of precise accessory which assists in controlling the dispensing of glue. It can play an important role in the connection with the glue valve and syringe. Recently, some users inquired about the information of the multi-point dispensing needle and the long dispensing needle. So this time, we will simply introduce the information of the multi-point dispensing needle and the relationship between the explanation and the long dispensing needle and the scope of application, mainly from the application precision. The specifications of multi-point dispensing needle and long needle are described.
Simple description of multi-point dispensing needle
As the name implies, a multi-point dispensing needle can dispense more than one-way glue on the surface of dispensing glue. This special dispensing needle has the same precision as a long dispensing needle. It has many fine and fine dispensing needle tubes with a dispensing accuracy far higher than other dispensing needles. Therefore, it is suitable for the precise glue quantity coating of infusion applicator and the complete performance of the cover plate coating, while the precision of the long dispensing needle is much higher. Through the length of needle tube, long needle tube ensures the stable flow control of glue quantity, so that the glue amount can be uniformly applied to the sealing bond of the product, and the specifications of multi-point glue dispensing needle and long needle can be varied for users to choose more.
Quality of glue applied in infusion apparatus
The exterior end of the catheter wall of the infusion device needs to be glued and strengthened by glued method. The completion of glued infusion device is also related to the choice of dispensing needle besides the application of automation equipment. It needs users to consider whether to choose long needle or multi-point needle for dispensing. The application of long needle is more than that of multi-point needle, because the specifications accuracy of long needle meets most of the requirements. Industry production, and dispensing long needle specifications and good corrosion resistance can be used for a long time in the links of infusion device gluing to ensure a high degree of consistency, so both of them can play a high degree of accuracy and quality control effect in the application of infusion device gluing or cover plate gluing.
Generally speaking, multi-point dispensing needle is more suitable for the production needs of small amount of glue. For example, the application demand of cover plate glue coating is not large, which causes the application market of multi-point dispensing needle is not wide.
