Classification of dispensing needles

Dispensing needles are divided into bayonet needles, stainless steel needles, brush needles, Teflon needles, spiral plastic seat needles, multi-tube needles, ultra-long stainless steel needles, stainless steel needles, curved needles, TT oblique needles, PP disturbing needles, etc. All of them are made by seiko, and all stainless steel tubes are made by unique technology, with precise polishing and no burr. It can realize the design of accurate glue, wire drawing prevention, double helix locking and large-area rotation, which is not only safer to cooperate with, but also easier to disassemble. With the development of various dispensing technologies, the requirements for dispensing needles are getting higher and higher. The precision of dispensing is not only determined by the dispensing valve, but also has a great influence on the dispensing effect. Especially in micro-dispensing industries such as LED and optical communication, high-precision dispensing needles have played their own advantages.

Thin-walled precision dispensing needle is a product developed by using the latest patented technology, which has attracted wide attention in led, semiconductor manufacturing and pharmaceutical industries. Its advantages are as follows:

High flow/accuracy/cost performance

■ Reduce the pressure of the delivery pump, improve the delivery performance and prolong the service life of the equipment.

■ Avoid clogging and wire drawing.

■ Products of different specifications are marked with different colors at the Ruhr mouth.

■ Patented thin-wall technology enables products with smaller caliber to have greater flow.

■ Very suitable for heating process application, reducing the time waste in cleaning process.
