Dispensing needles, divided into cards
Comparison of various needles
Oral needles, stainless steel needles, brush needles, Teflon needles, spiral plastic seat needles, multi-tube needles, extra-long stainless steel needles, stainless steel needles, elbow needles, TT oblique needles, PP interference needles, etc. All stainless steel pipes are made by Seiko. All stainless steel pipes are made of unique craftsmanship. They are precision polished and have no burrs. They can achieve precise glue output, eliminate wire drawing, double helix locking and large-area rotation design, which not only makes the fit safer but also easier to disassemble. (Various lengths and sizes can be customized)
Teflon dispensing needle
Teflon dispensing needle, also called quick-drying glue dispensing needle, is a special dispensing needle for quick-drying glue.
Stainless steel dispensing needle
Stainless steel dispensing needles have a wide range of applications, and because of their high quality, they have the longest service life. Therefore, it is loved by users.
PP flexible dispensing needle
PP flexible dispensing needle can effectively prevent the needle from scratching the panel and the glue is not smooth. It is a very practical dispensing needle.
TT oblique dispensing needle
The TT oblique dispensing needle is a full-plastic dispensing needle, which can be selected for those with low flow requirements. Its biggest feature is that it is not easy to block and can be used repeatedly.
Screw Dispensing Needle
Similar to bayonet dispensing needles, there is a thread on the base of the screw-top dispensing needle, which is more tightly and firmly combined with the barrel, so there are many users of screw-top dispensing needles.
Bayonet dispensing needle
Bayonet dispensing needles are the most commonly used dispensing needles, their price is relatively cheap, because there are two small ears on the base that can jam the syringe, so it is named.
High precision dispensing needle
With the development of various dispensing processes, the requirements for dispensing needles are getting higher and higher. The precision of dispensing is not only determined by the dispensing valve, but the precision of the dispensing needle also has a great influence on the dispensing effect, especially In the micro-dispensing industries such as LED and optical communication, high-precision dispensing needles have played their own advantages.
High precision dispensing needle
High precision dispensing needle
The thin-walled precision dispensing needle is a product developed using the latest patented technology, which has attracted widespread attention in the LED, semiconductor manufacturing, and pharmaceutical industries. Its advantages include:
High flow/high precision/high cost performance
■ Reduce the pressure on the delivery pump, improve the delivery performance and prolong the service life of the equipment
■ Avoid blockage and wire drawing
■ Products of different specifications are marked in different colors at Luerkou
■ Patented thin-wall technology enables larger flow rate for smaller caliber products
■ Ideal for heating process applications, reducing time wasted in the cleaning process
