[Case Study] Elimination of Defects in Small Nuts and Visual Inspection Work

A case where the change of the manufacturing manufacturer and the mechanization of inspection reduced the defect occurrence rate.

We would like to introduce a case where we proposed "switching manufacturers/automating the bagging process" to a battery manufacturer. There was a frequent issue with the small-diameter brass hex nuts used in battery production, where "the taps were cut at an angle." After our proposal, and following audits of two manufacturers, product defects have not occurred since the process changes were approved. 【Case Overview】 ■ Issue - There was a frequent issue with the small-diameter brass hex nuts used in battery production, where "the taps were cut at an angle." ■ Requirements for Solving the Issue - Select manufacturers that can ensure accurate quality control (to prevent occurrence) - Ensure that defective products can be detected during the bagging and inspection processes (to prevent outflow) *For more details, please refer to the related links or feel free to contact us.
