Control summarizes systematic design standards based on hundreds of full-line renovation projects of Haifeng, combining IATF16949, GB\/T21463 industry norms. Statistics show over78% capacity expansion failure results from mismatched beat and missing system integration instead of insufficient single machine output; traditional discrete equipment average scrap rate reaches 9.3%~16.1, while integrated automatic line can control reject below1.2%.

Control summarizes systematic design standards based on hundreds of full-line renovation projects of Haifeng, combining IATF16949, GB\/T21463 industry norms. Statistics show over78% capacity expansion failure results from mismatched beat and missing system integration instead of insufficient single machine output; traditional discrete equipment average scrap rate reaches 9.3%~16.1, while integrated automatic line can control reject below1.2%.
