Lowest Tin SolderÂ
The needle wire is fixed by fogging and discharging needles, plastic sets, and precise molds, which greatly reduces the welding process, thus avoiding the chemical pickling process and ensuring the safety and hygiene of each needle wire.
New Shell Design
The design of the ink guide groove is added under the needle’s nozzle to increase ink storage. The protruding part becomes the track when the needles are out. With the arc clamp limiter on both sides of the needle’s nozzle, the friction coefficient is reduced, the stability of the needle is increased and the smooth needle and ink flow are guaranteed.
