Quality Assurance

Product quality is a priority throughout our manufacturing operations. We focus on maintaining consistent specifications and reliable product performance through material verification, production process control, and appropriate quality inspection.

Before production, material requirements and product specifications are reviewed according to the confirmed order. During manufacturing, operators monitor key process parameters, including extrusion conditions, cooling, dimensional stability, and product appearance. Regular checks help identify deviations in diameter, wall thickness, or other important dimensions.

After production, products undergo applicable inspections according to their type, relevant standards, and customer requirements. These may include dimensional measurements, visual checks, and specific physical or mechanical tests.

For customers requiring additional inspection documents or third-party testing, our team can discuss the requirements before production and coordinate suitable arrangements.

Through these procedures, we work to ensure that every order meets its agreed quality requirements before shipment.
