In high-end
Forging and precision machining, raw material batch consistency is critical—it directly affects mechanical properties, service life, and delivery reliability. Liaoyuan recognizes this essential factor and has built a systematic raw material control framework based on three core principles: traceable sourcing, end-to-end
Quality Control, and standardized delivery. By forming long-term partnerships with leading steel mills, Liaoyuan ensures a stable supply of steel batches for reliable production.
I. Rigorous Supplier Selection: Building Long-Term Partnerships with Major Steel Mills
Material quality starts with supplier selection. Liaoyuan maintains a strict approved supplier list and partners exclusively with steel mills capable of large-scale production and standardized operations:
- Consistent Material Standards: Steel mills are required to supply materials in line with agreed specifications. Leveraging their mature smelting and rolling processes, we ensure consistent batch quality from the source.
- Full-Chain Traceability: Partner mills synchronize production batch numbers, inspection reports, and relevant data. Each batch is fully traceable to the steel mill’s production process, securing quality from the outset.

II. Path to Stable Delivery
1. Source Traceability
- Sign raw material quality assurance agreements with steel mills, specifying smelting processes, chemical compositions, inclusions and other key parameters.
- Adopt barcode/QR code systems to assign unique IDs to each steel billet batch, enabling full-chain tracking.
2. Incoming Material Inspection
- Preliminarily inspect raw material appearance, nameplates, specifications, dimensions and inspection certificates upon arrival.
- Use spectrometers to verify chemical compositions, ensuring compliance with agreed standards.
- Inspect metallographic structure via metallographic microscopes to avoid out-of-tolerance issues.
- Conduct ultrasonic testing (UT) on high-end bearing materials to eliminate internal defects.
- Perform end-quench and impact tests on special steels to verify hardenability and impact energy.
3. Regular Communication with Steel Mills
- Hold regular meetings with steel mill after-sales teams to address raw material issues promptly.
- Conduct monthly comprehensive evaluations on delivery and quality, and annual audits of cooperative steel mills to ensure supply stability.
III. Advantages of Raw Material Source Control
1.Stable Supply Chain: Long-term cooperation with large steel mills reduces supply disruption risks, supporting orderly production planning.
2.Consistent Batches: Standardized steel mill systems and full-chain traceability ensure uniform material composition and performance across batches.
3.Controllable Quality Risks: Quality agreements, multi-level inspections and regular audits prevent unqualified raw materials from entering production.
4.Optimized Costs: Reduce rework, inventory backlog and emergency procurement costs, improving overall production efficiency.
5.Global Competitiveness: Internationally certified raw materials and stable quality build a reliable brand image in the global forging industry.
6.Enhanced Customer Trust: Traceable quality systems and stable performance adapt to harsh working conditions, strengthening long-term cooperation.
Raw material source control is fundamental to high-end forging and precision machining. With a complete system covering forging,
Heat Treatment, machining and quality inspection, Jiangyin Liaoyuan achieves full-chain traceability and stable delivery through a closed loop of
source locking + process control + terminal verification and in-depth steel mill cooperation. Moving forward, Liaoyuan will deepen digital monitoring, standardized delivery and green manufacturing to provide more efficient and reliable solutions—our material and processing quality is always the solid foundation for stable equipment operation, regardless of harsh working conditions.
