Twin screw barrel for extruder
The twin screw and barrel is one of our primary product ranges, including the counter-rotating parallel twin screw barrel, co-rotating parallel twin screw barrel and conical twin screw barrel.
We usually manufacture them with the base material of 38CrMoAlA and 40Cr. If you have a much higher requirement on the anti-abrasion and anti-corrosion, the material of SKD61 and fully hardened powder are both available. Depending on the different process applications, different types of surface treatment are provided, such as nitriding, alloy sprayed, hard chrome plated, etc.
We are able to provide any parallel screws from ф45mm to ф200mm, conical screws from ф25/ф45 to ф92/ф188, with maximum length 8000mm and their correspondent barrels (cylinders).
Technical data:
Nitriding thickness: 0.5-0.8mm
Nitriding hardness: >920HV
Surface roughness: Ra0.4um
Surface Straightness: 0.015mm/m
We also manufacture the specification (diameter, length-diameter ratio, nitriding thickness, nitriding hardness) per your detailed request.
