In high-end
Forging and precision machining, batch consistency of raw materials directly determines product mechanical properties, service life and delivery reliability. Recognizing this key link, Liaoyuan has built a systematic raw material control system based on three core principles—
traceable source, full-chain Quality Control and standardized delivery, and established long-term partnerships with large steel mills to ensure stable steel batch supply.
I. Strict Supplier Selection: Long-term Stable Cooperation with Large Steel Mills
Raw material quality starts with supplier selection. We have a rigorous list of qualified suppliers, partnering exclusively with large steel mills capable of large-scale production and standardized management:
- Unified Material Standard: Require steel mills to supply stably per signed material standards. Leveraging their mature smelting and rolling systems, we ensure steel batch consistency from the source.
- Full-chain Traceability: Require cooperative steel mills to synchronize production batch numbers, quality inspection reports and other data. Each raw material batch is traceable to the steel mill’s production process, securing quality at the source.

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
- Stable Supply Chain: Long-term cooperation with large steel mills reduces supply disruption risks, supporting orderly production planning.
- Consistent Batches: Standardized steel mill systems and full-chain traceability ensure uniform material composition and performance across batches.
- Controllable Quality Risks: Quality agreements, multi-level inspections and regular audits prevent unqualified raw materials from entering production.
- Optimized Costs: Reduce rework, inventory backlog and emergency procurement costs, improving overall production efficiency.
- Global Competitiveness: Internationally certified raw materials and stable quality build a reliable brand image in the global forging industry.
- 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.
