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.
