What does Hongqing check in a first-article inspection?<\/p>\n\t\t\n<\/span>\n
\n \t\t\t
\n \t\t\t
Hongqing starts every batch with a first article, which QC checks against the drawing and the signed-off sample in 4 areas: key dimensions (measured on 2D vision systems or a CMM), appearance (sink, flash, scratches, color and gloss), fit (trial assembly with mating parts) and functional requirements. Mass production starts only after the first article matches your approved sample and the record is filed; if it fails, we adjust process settings or the mold and make a new first article. This step stops problems before mass production and avoids reworking a whole batch.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

What does each part of Hongqing's 20-person QC team do?<\/p>\n\t\t\n<\/span>\n
\n \t\t\t
\n \t\t\t
Hongqing's 20-person QC team covers 6 areas: incoming inspection, in-process inspection, dimensional measurement, reliability testing, assembly checks and outgoing inspection. Incoming inspectors check resin, metal parts, electronic components and packaging; patrol inspectors spot-check molding, painting, printing and assembly lines; dimensional checks use 4 2D vision measuring systems and a CMM; reliability tests use a temperature\/humidity chamber, salt spray tester and impact tester; and outgoing inspection samples per GB\/T 2828.1 AQL or your standard. When something is off, the team records it, reports it and drives the fix.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

How does Hongqing confirm and measure key dimensions and tolerances?<\/p>\n\t\t\n<\/span>\n
\n \t\t\t
\n \t\t\t
Hongqing measures key dimensions on 4 2D vision measuring systems and a CMM, and the dimensions and tolerances on your 2D drawing are the standard. In the DFM review we confirm which dimensions are critical and whether the tolerances are achievable in tooling and molding, and suggest changes where they are not. Trial samples and every batch's first article are measured, production parts are spot-checked on a set patrol frequency, and outgoing inspection follows the agreed sampling standard. Without a 2D drawing, our engineers can propose key dimensions from your 3D files and assembly, which become the inspection basis once you approve them.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

What do ISO 45001, BSCI and Sedex mean for buyers?<\/p>\n\t\t\n<\/span>\n
\n \t\t\t
\n \t\t\t
Beyond ISO 9001 (quality), ISO 14001 (environment) and IATF 16949 (automotive quality), Hongqing is certified to ISO 45001 for occupational health and safety and has passed BSCI and Sedex social compliance audits. The first three show that products, environmental impact and processes are managed systematically; the last three show that working conditions, labor practices and safety have been checked by third parties, which many European and US brands require when choosing suppliers. Scans of our ISO 9001, ISO 14001 and IATF 16949 certificates and BSCI and Sedex audit documents are on this page; email us for electronic copies, or audit us against your own supplier checklist.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n\n<\/div>\n\n<\/div>\n\n<\/section>\n
