FAQs About Metrology and Inspection Lab Capabilities
What’s the core difference between FAI and regular in-process inspection?
expand_less expand_moreA: FAI is full-feature comprehensive verification for first-run new/modified parts to set quality baseline following AS9102; in-process inspection focuses on key dimensions during production to monitor real-time process stability.
Can inspection reports be customized into specified formats?
expand_less expand_moreA: Yes, standard AS9102 FAIR available and customized PDF/Excel/CSV reports supported as per clients’ internal QA system requirement.
How do you handle non-conforming defective components?
expand_less expand_moreA: Defective goods are isolated and tagged immediately; QA team analyzes root cause to decide rework/scrap/concession and implement corrective actions to prevent recurring defects.
How to solve inconsistency between our incoming inspection and your outgoing test result?
expand_less expand_moreA: We start full record review & sample recheck immediately, optimize inspection method and arrange replacement production expediently once our deviation is confirmed.
Is SPC process capability data available for bulk production orders?
expand_less expand_moreA: Yes, we supply control charts, Cpk/Ppk index and trend analysis to support clients’ lot incoming acceptance judgment.
Are international metric/imperial & special industry inspection standards acceptable?
expand_less expand_moreA: Our lab is proficient in ISO/ASME norms and flexible to switch unit or test protocol to satisfy global clients’ customized requirements.
