The frame made by 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 moulds, 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 secant needle is similar to each other. The stabilizing device of cross needle can make the needles run steadily and increase the ink storage at the same time.
