Flange nozzle is installed at the front end of the barrel and the mold docking components, in the storage of materials to establish the back pressure, get rid of gas, to prevent the plastic melt casting, improve the plasticizing capacity and measurement material; injection mold and mold mouth formation Pressure, keep the nozzle and the mold nozzle mouth good contact, thus forming a sealed flow channel, Jinyang flange nozzle materials are all alloy, SDK61, SACM645 alloy steel, 38CrMoAla alloy structural steel, quenched, quenched, nitrided, or The whole hardening. Jinyang screw flanged nozzle specifications JY-self-locking nozzle: (inner spring, outer spring) for good mobility of plastic, anti-casting. JY-Mixing nozzle: (built-in mixing element) for adding color masterbatch color mixing and more fully plasticized. JY-extended nozzle: for the depth of the mold manufacturing. JY-short shot Tsui: general-purpose nozzle. JY-Shaft flange: Universal flange. JY-conjoined Shot flange: for the import of small precision machine used.
