Pretty bottles, ugly downtime

I love a good-looking package, but our lines keep me honest. Every time a bottle gets a dramatic shoulder or a featherweight neck, I start budgeting for jams, torque drift, and rework.

Recent hits: cap ribs too shallow for our chucks, so we crank torque and still get loose caps and leaks in transit. High-gloss labels blow out the vision cameras and spike false rejects. A new amber bottle fooled our ultrasonic level sensors and we had operators babysitting fill heights all shift.

None of this is rocket science; it's timing. If industrial design loops in ops before tooling, we can add a matte code window, deepen knurls 0.5 mm, spec a stiffer 28-410 neck, or change pigment load so sensors see the meniscus. Same shelf appeal, far less pain at 220 bpm.

For those straddling ID and manufacturing: what simple, high-leverage rules do you use to keep designs fillable and inspectable without neutering the look? What small tweak saved you the most uptime?
