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.
A screw and barrel comprise the essential components of a screw extruder, widely used in industries like plastics manufacturing. The screw Barrel Manufactured by Mahira Polyglobal is a helical rod, that rotates within the cylindrical barrel, conveying raw material from the hopper toward the die while applying heat and pressure to melt it. The barrel, heated to facilitate melting, provides containment and pressure control, housing various temperature zones for material processing. Together, they form the core of the extrusion process, transforming raw materials into desired shapes or forms efficiently and effectively. Are you looking for Screw Barrel Manufacturer Near You?
