There are four special elastics held on a rebound that lighten the pressure of the needle bar, working silence. The frame is made of PC polycarbonate, Polycarbonate is colorless, transparent, heat resistant, impact-resistant, flame retardant, BI grade, and has good mechanical properties at normal use temperatures. From the outer needle shell to the needle thread, and even every part, we have carried out layer screening and testing to make a needle run smoothly, save more ink, fast color, low skin loss, and every detail is critical.
The needles 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. 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.
