Product Identification and Traceability - Jiangyin Liaoyuan New Energy Co.,Ltd.

The Cornerstone of Quality Assurance and Customer Trust in Forging

In the forging industry, product quality is directly linked to corporate reputation and downstream operational safety. Product identification and traceability management is a core quality function that spans the entire product lifecycle. It serves as a “quality passport,” ensuring that every forged component can be accurately tracked from raw material to finished product, with responsibilities clearly defined and verifiable.

This article explains how forging manufacturers can establish a robust identification and traceability system to strengthen quality control and build long-term customer trust.

Why Product Identification and Traceability Matter

For forging manufacturers, product identification and traceability are not administrative burdens—they are critical enablers of competitiveness and risk control.

1, Enhanced quality control

Clear identification distinguishes inspection status at each stage, preventing nonconforming products from entering subsequent processes or shipment.

2, Rapid root cause analysis

A structured traceability chain allows quality issues to be traced quickly to their origin, providing a factual basis for corrective actions and minimizing losses.

3, Meeting customer requirements

Many downstream industries impose strict traceability requirements. A mature traceability system improves compliance and strengthens long-term cooperation.

4, Clear responsibility definition

Complete lifecycle records define accountability and provide objective evidence for dispute resolution, protecting both supplier and customer interests.

Key Elements of Identification and Traceability Management in Forging

Effective management must cover the full process—from raw material intake to finished product delivery—supported by clear responsibilities and standardized procedures.

1, Clear Role Definition: Ensuring Accountability at Every Step

Efficient traceability relies on defined responsibilities and cross-department coordination:

a. Warehouse personnel

Verify material identification, confirm consistency with incoming documentation, and restore missing or unclear markings

b. Production workshop

Ensure identification integrity during production and delivery, and implement marking transfer requirements.

c. Quality inspection personnel

Control inspection status identification, review traceability records, and monitor compliance with marking standards.

2, Full-Process Identification Standards: Assigning a “Quality Identity” to Every Component

Identification requirements must be accurate, complete, clear, and durable, with different focus points at each stage.

1) Raw material identification: controlling quality from the source

After raw material inspection approval, warehouse staff verify original markings such as material grade and heat number traceability, store materials by classification, and attach identification tags. During cutting, material information—including heat number and material specification—is transferred to the billet. Cut-offs and remnants are identified and managed by designated personnel.

2) Product identification: continuous tracking throughout production

Product identification may include stamping, nameplates, or other approved methods in accordance with the marking process specification:

a. Forgings are marked with heat number, material grade, and routing card number

b. Customer-specified product numbers are applied when required

c. Nameplates and certificates of conformity are attached prior to final delivery

3) Inspection status identification: defining the “quality clearance”

Inspection status is clearly distinguished using labels, color codes, or designated storage areas to prevent mixing:

a, Accepted products: green identification or labels, stored in qualified areas

b, Nonconforming products: red “X” or labels, isolated storage

c, Pending inspection products: pending labels or designated areas

Products without clear identification are treated as uninspected and are prohibited from further processing or warehousing.

3, Traceability Management: Building a Complete Reverse Traceability Chain

The core of traceability is the ability to establish a reverse traceability chain for forged components traceability, enabling full tracking from finished product back to raw material.

(1) Complete traceability workflow

A typical traceability path includes: Customer feedback → Shipping documents → Contract / order → Process, production, and inspection records → Material issue records → Raw material receipt → Supplier information

This structure enables rapid access to all relevant data across the entire lifecycle.

(2) Unique traceability identification system

Unique identifiers are essential for accurate tracking:

a. Routing card number

The primary internal traceability identifier, typically composed of the sales order number plus product sequence number, extended for single-piece flow if required.

b, Product number

Applied when specified by the customer and linked to internal batch numbers through traceability records.

(3) Special case handling

If markings are lost during thermal processing, detailed records of heating, forging, and heat treatment operations are maintained. Supporting materials such as process maps or photographs may be used as supplementary traceability evidence.

4, Records and Audits: Ensuring Effective Implementation

Standardized records and regular inspections ensure the traceability system functions as intended:

a, Record control

All traceability records must be complete, properly signed, and retained in accordance with defined retention periods.

b, Routine inspection

Quality inspectors conduct daily monitoring, while the quality department performs monthly process discipline audits.

5, Managing Customer-Specific Traceability Requirements

When customers specify additional traceability requirements, these are implemented in accordance with approved procedures and documented authorization.

Conclusion: Traceability Is Both Quality Assurance and Trust

As competition in the forging industry intensifies, product identification and traceability have evolved from optional practices to essential quality foundations. They improve internal quality efficiency while meeting increasingly stringent customer requirements and reinforcing a manufacturer’s reliability.

Standardized identification and traceability management reflects respect for quality and responsibility toward customers. It is also essential for customers sourcing critical forged components for heavy industrial applications. Continuous optimization of traceability systems will remain a key driver of sustainable, high-quality development for forging manufacturers.

For customers requiring documented traceability systems for forged shafts, rings, or critical transmission components, detailed quality documentation can be provided upon project discussion.
