Quality Control Inspector Cover Letter Example

Customer rejects at our plant fell from 180 to 40 parts per million in two years after the plant adopted a first piece and last piece check I proposed for every run. I am applying for the Quality Control Inspector opening at Great Lakes Drivetrain Components.

At Lakefront Components, an automotive supplier, I inspect machined and molded parts against GD&T drawings and control plans. An inline vision system checks every part, about 1,800 a shift, and each hour I measure a five-piece sample with calipers, plug gauges and a CMM running PC-DMIS, then record it on a control chart. When a trend moves toward the limit, I stop the line. Nonconformances get photos and an 8D report, and I close 90% of them within five working days.

Forty new part numbers next year means a lot of first article layouts and PPAP submissions, and that is work I already do: at Lakefront I run PC-DMIS programs for first article layouts and support PPAP submissions for new parts. The IATF 16949 system at Great Lakes Drivetrain would feel familiar, and so would its customer audits; I have supported two with no major findings. You ask for an inspector to calibrate gauges and keep records, which I do on a monthly schedule for our shop floor gauges. I began as a machine operator running three injection molding machines on nights, so I know how a molded part drifts before it ever reaches the gauge.

Bring me a part your team finds hard to hold, with its drawing, and I will talk you through how I would set up the first piece check for it. Last month's control chart from my line, with part numbers removed, is ready to share.
