Quality Testing Methods for aerospace fasteners suppliers and how to control quality
For aerospace fasteners suppliers, ensuring high-quality products is crucial. Here are key quality testing methods and control measures:
1. Material Inspection: Conduct chemical analysis and mechanical property tests to verify material conformity with standards like ASTM or AMS.
2. Dimensional Checks: Utilize precision instruments (calipers, micrometers) to verify dimensions against engineering drawings.
3. Surface Inspection: Employ techniques such as visual inspection, dye penetrant testing, or fluorescent penetrant inspection (FPI) to detect surface defects.
4. Mechanical Testing: Perform mechanical tests like tensile, shear, and fatigue tests to validate strength and durability.
5. Corrosion Resistance: Subject fasteners to salt spray tests (ASTM B117) to assess corrosion resistance.
6. Certifications and Documentation: Ensure compliance with certifications (AS9100) and comprehensive documentation (material certificates, test reports).
To control quality:
– Supplier Audits: Regularly audit suppliers’ facilities and processes to ensure adherence to quality standards.
– Process Controls: Implement process controls such as statistical process control (SPC) to monitor manufacturing variables and maintain consistency.
– Quality Management System (QMS): Establish a robust QMS to document procedures, track non-conformities, and facilitate continuous improvement.
– Training and Skills Development: Train personnel on quality requirements and provide skills development to enhance competencies.
By integrating these methods and controls, aerospace fasteners suppliers can consistently deliver high-quality products that meet stringent industry standards and customer expectations.
