Dispensing needles are divided into bayonet needle, stainless steel needle, brush needle, Teflon needle, spiral plastic seat needle, multi-tube needle, long stainless steel needle, stainless steel needle tube, curved mouth needle, TT oblique needle, PP nuisance needles, etc. All of them are made of fine workmanship, all stainless steel tube are used unique technology, precision polishing without burrs, can realize precise dispensing, eliminate pulling, double spiral locking and large area rotation design. All of them are made of fine workmanship, all stainless steel tubes are made of unique technology, precision polishing without burrs, which can realize precise glue output and eliminate pulling, double screw locking and large rotating design, which not only makes the fit safer but also makes it easier to disassemble. (Various lengths and sizes can be customized) With the development of various dispensing processes, the requirements for dispensing needles are also higher and higher, the accuracy of dispensing is not only determined by the dispensing valve, the accuracy of the dispensing needle also has a great impact on the dispensing effect, especially in the LED, optical communications and other micro-dispensing industry, so high-precision dispensing needles play out their advantages.
Thin-wall precision dispensing needles are products developed using the latest patented technology, which have attracted widespread attention in the LED, semiconductor manufacturing and pharmaceutical industries, with the following advantages:
High flow rate/high precision/cost-effective
■ Reducing the pressure on the transfer pump, improving the transfer performance and extending the service life of the equipment
■ Avoiding clogging and pulling
■ Different sizes are marked with different colors on the luer port
■ Patented thin-wall technology allows for higher flow rates in smaller diameters
■ Ideal for applications that require heated processes, reducing time wasted in the cleaning process luer port color Standard Material Product Specification Plating/Coating AFSL Specification I.D./O.D.
