Quality Control Throughout Production
Product consistency is essential for steelmaking and foundry operations. Our quality control process covers raw materials, production monitoring, laboratory testing, and shipment verification.
Raw Material Inspection
Quality control begins before production.
Incoming raw materials are inspected for:
Chemical composition
Physical condition
Supplier conformity
Production suitability
Only materials meeting internal production requirements are approved for use.
Production Monitoring
During production, key process parameters are monitored to maintain consistency between batches.
Production monitoring may include:
Furnace operation control
Temperature monitoring
Smelting process supervision
Batch identification and tracking
This helps reduce variations between production lots.
Laboratory Testing
Samples are collected and tested before shipment.
Testing may include:
Silicon (Si)
Calcium (Ca)
Manganese (Mn)
Carbon (C)
Phosphorus (P)
Sulfur (S)
Testing results are compared with customer specifications and applicable product standards.
Batch Traceability
Each production batch can be identified and tracked through production and shipment records.
This allows:
Batch verification
Shipment matching
Production record review
When required by customers.
COA Documentation
Certificate of Analysis (COA) reports can be provided for each shipment.
Typical COA information includes:
Product name
01
Batch number
02
Chemical composition results
03
Testing date
04
Shipment reference
05
The report provides documented verification of the supplied material.
Third-Party Inspection
Independent inspection services can be arranged upon customer request.
Inspection scope may include:
Chemical composition verification
Quantity inspection
Packaging inspection
Container loading inspection
Third-party inspections can be conducted before shipment according to contractual requirements.
Export Quality Documentation
Available documents may include:
- Certificate of Analysis (COA)
- Packing List
- Commercial Invoice
- Bill of Lading
- Certificate of Origin
- Third-Party Inspection Report (if required)
Documentation is prepared according to customer and destination market requirements.
