Detailed

Screw head (plastic head, rubber head, rocket head) has a screw head, reverse ring, meson three-piece set, installed in the screw front, for the back pressure in the melt when plastic, The plastic melt into a good mold material inside. Jinyang screw head material is all alloy (full hardening powder alloy steel), SDK61, SACM645, after quenching, quenching, nitriding, full hardening and other processing technology, Jinyang screw head advantage is durable precision, good sealing effect. Applicable to the import of all-electric precision molding machine injection precision gears, connectors, light guide plate lenses and other precision electronic products
