Premium metal fabrication, hot forging, casting, and precision multi-axis CNC components built to international engineering standards.
Twin screw extruders represent the high-performance benchmark of polymer compounding, reaction kinetics, and bulk devolatilization. Across modern industrial frameworks, the balance has shifted from basic thermal extrusion towards complex thermo-mechanical processes demanding absolute torque density and predictable wear cycles. Global processing lines rely on twin-screw geometry to achieve precise dispersive and distributive mixing under tight residence time distributions.
As polymer formulations incorporate high loadings of abrasive fibers, corrosive flame retardants, or shear-sensitive recycled polymers, the requirements placed on the mechanical integrity of extruder barrels, shafts, and kneading elements have escalated exponentially. Our focus on metallurgical perfection ensures that every component is engineered to handle these intense stress fields.
A heritage of metallurgical expertise, state-of-the-art Japanese manufacturing equipment, and professional custom-engineering capabilities.
Founded in 1996 as an owner-managed SME corporation, Ningbo Jiangbei XinYe Metal Works Co., Ltd. has evolved over nearly three decades into a leading engineering partner for precision metallurgical solutions. Strategically situated in the Ningbo Jiangbei Industrial Zone, our facility is within three hours of Shanghai International Airport via the high-speed train network.
Our expansive industrial complex features 16,000 square meters of production floor, complemented by an additional 11,000 square meters of construction. Out of our 130-strong workforce, 80 are dedicated production specialists, and 50 are highly qualified engineers, product developers, quality inspectors, and managers.
We are a certified ISO 9001-2015 and SA8000 manufacturer. Our core technical capability encompasses multi-axis CNC machining, hot alloy forging, wax die stainless steel casting, stamping, extrusion, and advanced chemical surface treatments like anodizing and electropolishing.
Providing the heavy machinery and precision instrumentation required to manufacture durable twin-screw extruder subsystems.
Equipped with friction press machines capable of delivering press forces from 300 to 1,000 tons, and column hydraulic machines from 100 to 630 tons. Ideal for establishing deep structural integrity in high-torque extruder shafts and thick-walled barrels.
State-of-the-art CNC machining centers, turning systems, and milling units imported from Japan. Our precision tools achieve dimensional tolerances within 0.001mm, critical for processing flight paths of co-rotating twin-screws.
High-precision investment casting lines for complicated component shapes, combined with high-tonnage aluminum die casting. This allows us to manufacture complex feed housings and gearbox cooling flanges with minimal draft angles.
Custom engineering for the demanding, high-throughput applications that drive regional industrial sectors.
Compounding base polymers with up to 85% Calcium Carbonate (CaCO3), Talc, or Titanium Dioxide requires extreme wear resistance. Our custom alloyed screw segments and bimetallic barrels prevent early mechanical erosion, safeguarding line output over thousands of running hours.
Processing glass-fiber reinforced Polyamides (PA6/PA66), Polycarbonate (PC), and Polybutylene Terephthalate (PBT) requires precise shear force control. Our customized kneading and mixing block geometries ensure optimal fiber length distribution without degrading the polymer matrix.
Formulating PLA, PBAT, and starch-based biodegradable compounds is temperature-sensitive and reaction-driven. We manufacture specialized continuous-reaction barrels featuring dynamic cooling channels to prevent thermal degradation.
Transitioning from mechanical components to intelligent, high-wear resilient cyber-physical extrusion systems.
To resist chemical and abrasive attack, our technical roadmap integrates Powder Metallurgy (PM) steels and Hot Isostatic Pressing (HIP) technologies. This creates screw elements with hardness profiles exceeding 62-65 HRC without sacrificing core structural toughness.
Integrating thermo-sensors inside the extruder barrel allows real-time monitoring of melt heat profiles. Automated feedback loops adjust regional heating bands, ensuring process stability during processing variations.
Next-generation co-rotating gearboxes feature integrated torque sensors that communicate directly with the main PLC. Safe-trip mechanism designs prevent catastrophic shaft shearing when processing highly filled or viscous melts.
Why sourcing from Ningbo Jiangbei XinYe Metal Works Co., Ltd. ensures continuous production, pricing stability, and quick delivery.
In a global marketplace marked by volatile raw material costs and fluctuating freight timelines, the resilience of our localized supply network provides a distinct advantage. Being based in Ningbo puts us in direct contact with local raw material suppliers, cutting transit times and reducing overheads.
We work 6 days a week with 16-hour production shifts to maintain rapid order processing. In periods of high demand, we can transition to a full 24/7 continuous operation within 30 days. This capability, combined with nearby logistics access to Ningbo Port (the world’s largest cargo port by tonnage), guarantees consistent production and shipping timelines.
