Quality Control

ISO 9001 Certification

Our company operates under the ISO 9001 quality management system, applying strict inspection and monitoring at every stage of production. Continuous evaluations ensure that each product meets international standards and maintains consistent high quality.

Raw Material Control

We manage raw material quality through supplier evaluation, incoming inspections, and procurement oversight. Only materials that meet defined physical and chemical standards are approved for production.

Procurement Activity Control

The Purchasing Department works closely with the Quality Management Department to prepare procurement guidelines that align with company standards. All purchases require a signed Procurement Contract and Quality Assurance Agreement with approved suppliers, ensuring stable supply and reliable quality.

Raw Material Inspection Standards

The Quality Management Department establishes inspection requirements for incoming wire, covering physical properties and chemical composition. Trained inspectors issue inspection reports and immediately report any abnormalities. Only raw materials that fully meet specifications are released into production.

Inspection Specifications

• Physical properties: tensile strength, elongation, hardness (values according to product standards).

• Chemical composition: strict compliance with ASTM, DIN, or ISO standards depending on application.

• Size tolerance: wire diameter typically ±0.02 mm – ±0.05 mm depending on type.

Quality Assurance Goal

Through careful supplier management, contract-based procurement, and detailed raw material inspection, we ensure that every batch of material contributes to stable, reliable, and high-performance products for our customers worldwide.
