Explore our premium industrial metal components manufactured using state-of-the-art forging, die-casting, and multi-axis CNC techniques.
Established in 1996 | Owner-Managed SME Corporation
Ningbo Jiangbei XinYe Metal Works Co., Ltd. is located in the Ningbo Jiangbei Industrial Zone, situated strategically within a 3-hour commute from Shanghai International Airport via the high-speed rail network. Spanning a total production footprint of 16,000 square meters, with an additional 11,000 square meters of construction area, we are a leading custom manufacturer of precision mechanical parts.
We feature a skilled workforce of 130 professionals, including 80 production line specialists and 50 personnel dedicated to R&D, engineering, and quality management. Our core strengths cover complete processing routes for CNC machining, aluminum alloy forging, wax die stainless casting, stamping, extrusion, and advanced surface treatments (anodizing and electro-polishing).
A comprehensive technical analysis of material performance, wear mechanics, and structural alignment for heavy machinery feed systems.
In high-torque industrial feeding applications—such as industrial wood chippers, tub grinders, forestry harvesters, recycling shredders, and bulk material conveying systems—the Feed Roller with Shaft is the primary component interface responsible for mechanical energy transfer. It must handle high radial forces, extreme shock loading, and highly abrasive environments.
Standard feed rollers often experience mechanical failures due to wear on the outer teeth or fatigue at the shaft-roller junction. The integration of a single-piece, robustly joined roller body and shaft provides maximum torsion capability, preventing shaft slippage, keyway deformation, or premature structural shearing.
The performance of a feed roller system depends heavily on its raw materials. At Xinye Metal Works, we customize the metallurgy based on the application:
| Component Element | Material Used | Tensile Strength (MPa) | Yield Strength (MPa) | Hardness Rating (HBW) |
|---|---|---|---|---|
| Roller Core Body | Q345B Steel | 470 - 630 | ≥ 345 | 135 - 180 |
| Precision Drive Shaft | 42CrMo Alloy Steel | ≥ 1080 | ≥ 930 | 280 - 320 (Post-Tempering) |
| High-Wear Teeth Components | NM400 Steel / Overlays | ≥ 1250 | ≥ 1000 | 370 - 430 |
Unbalanced rotating elements can cause bearing damage and systemic failure in heavy equipment. Our facility uses Japanese CNC machining centers to hold tight tolerances (±0.01mm on shaft bearing journals). We run dynamic balance testing to eliminate high-speed vibration, ensuring the feed roller operates smoothly at high RPMs, which extends the operational lifespan of the entire gearbox drive system.
Addressing the supply chain challenges, international logistics, and localized compliance demands of global OEMs.
OEM parts buyers require predictable manufacturing schedules. We maintain a flexible work shift system, operating 16 hours a day over 6 days as standard, with the ability to ramp up to a 24/7 continuous production schedule within 30 days to handle demand surges.
We manage international shipping and logistics to Europe, North America, and Russia. All parts are packed in reinforced, seaworthy export packaging, including custom crates, rust-preventative oil coatings, and vacuum-sealed barriers to prevent corrosion during ocean transit.
Our production runs are certified to ISO 9001:2015 and SA8000 standards. This guarantees that all material certifications, traceability records, dimensional inspection charts, and labor conditions meet global compliance benchmarks.
