Screws and barrels for extruder machine Depth of nitrated layer: 0.5-0.8mm Hardness of nitration: 900-1020hv Fragility of nitration: less than grade 1 Surface roughness: ra 0.4um Surface hardness of nitrated cr coating layer:í²950hv Hardness of bimetallic layer: hrc55íp-72íp Thickness of cr-coating layer: 0.03-0.08mm Depth of bimetallic layer:ú+2mm Specifications of screw: ª)20-ª)250 l/d 15-50 we offer various types of extruder screws and adjust to different compression ratio, which can fulfill customer's requirement perfectly.
Ningbo Superior Machinery and over 30-year-old factory with ISO 9001:2008 certificated, manufacturing screws, barrels for injection and extrusion processing. Specifications of our Ni-based bimetallic barrel: Basic Material for body: superior pre-hardening material 4140 Alloy powder: Nickle-based self-melting alloy powder from American Wall Colmonoy Corporation Processing: vacuum sintering cladding ( we're the first and unique Chinese factory applying this technology to barrel production since 2009!) Hardness: 56-60 HRC Service life: 3~6 times than bimetallic barrels processed by high temperature centrifugal casting Application: halogen-free plastic, the high abrasion, corrosion materials adding high fibre, carbon fiber, mineral fiber, ceramic, magnetic powder, metal powder etc. Advantage: more stable molecular structure, higher density of the alloy power than common bimetallic barrels.
