Quality Control Process

Quality control is implemented throughout key manufacturing stages to prevent deviation and ensure conformity with specified requirements.
Control activities may include incoming material verification, process monitoring and final verification, depending on product type and manufacturing route.

Rather than focusing solely on rejection, the control process emphasizes early detection, prevention and corrective alignment.
Non-conforming conditions are managed through defined handling procedures to prevent unintended use and to support continuous improvement.

This process-oriented approach supports stable output quality across different production batches and project types.

Our Quality Control Process ensures that every product leaving our facilities meets the highest standards of performance, safety, and reliability. We strictly follow ISO 9001:2015 requirements for inspection, records, and continuous improvement.

Incoming Material Inspection

  • First and critical checkpoint in the QC system

  • Checks include:

    • Chemical composition

    • Mechanical properties

    • Supplier certificates and compliance

  • Samples or test coupons are retained per product or process requirements

  • Inspection records are documented on-site for full traceability

Standardized In-Process Quality Checks

  • Follow stepwise inspection procedures for each stage

  • Dimensional, surface, and functional checks performed with calibrated instruments

  • Tools are regularly verified and calibrated

  • Critical inspections are documented to maintain ISO compliance and ensure on-time delivery

Non-Destructive Testing (NDT)

  • Applied to critical or high-stress components

  • Methods include: UT, MT, PT, RT

  • Ensures internal structural integrity without affecting product functionality

Final Inspection & Testing

  • Comprehensive verification before shipment

  • Dimensional checks, functional testing, surface inspection

  • Compliance against customer specifications and internal standards

  • Records retained for traceability and audits

Calibration, Tool Verification, and Training

  • Regular calibration of gauges, calipers, hardness testers, and other instruments

  • Verification of measuring tools before inspections

  • Periodic staff training on measurement methods, new equipment, and standards

  • Ensures consistent accuracy, reliability, and ISO compliance

Continuous Improvement

  • Non-conformities trigger corrective and preventive actions (CAPA)

  • Production and inspection data analyzed for process optimization

  • Feedback integrated into training and SOP updates

  • Supports ongoing enhancement of quality, efficiency, and customer satisfaction
