Product: Extruder screw barrel
Quenching hardness: HRC55-62
For good plasticizing effect, we have different designs of screw and barrel for extruder or injection to meet customer’s demand.Our factory manufactures with high-quality material, applying the method of hardening and tempering and nitriding, thus it enjoys the characteristics of long working life, wear resistance, and anti corrosion. Besides, the technique of hard alloy spraying or chrome plating can be used on the working surface of screw, which will make it have better using effectiveness. We can produce for Haitian, Chenhsong, Demag, Engle, Nigrobossi, KMD, NPM, BOY, HUSKY, Nippon Steel, Toshiba, Nissei, Mitsubishi, CINCINNATI, BATTENFELD, KRUSSMAFFEI, BAUSANO, WEBER, AMUT and so on.
Extruder screw diameter: 15 – 300 MM
LD for extruder screw: 1:5 – 1:65
Extruder barrel OD: 20-500 MM
