AI visual inspection and production intelligence for coil coating

Catch coating defects like bare spots, streaks, and scratches, and more across the full strip in real time. Turn what you learn into less waste and smarter production.

What if a bad roll never made it out your factory again, and your line got smarter and more efficient with every run? 

CATCHING DEFECTS EARLY MATTERS

The cost of a single missed defect quickly compounds.

What one escape costs
A coating defect you catch late costs more than the coil.
Wasted coil
Hundreds of feet run before the coil is pulled
$140
Line downtime
Stopped to rethread and re-web
$400
A downgraded roll
Sold as seconds, or scrapped outright
$900
A rejected shipment
The converter downstream catches it first
$5,000+
WHAT A MISSED STREAK BECAME
$6,420+ & a hold
The converter who got the bad roll now inspects every shipment you send, or quietly moves the program to a supplier they don’t have to double-check.
One escaped web defect, start to finish: your line’s numbers may differ.

Coil coating lines just got smarter.

How It Works

We manage the system that lets your line learn.

Specifically designed for coil coating’s toughest inspection challenges.

01

Camera

The eyes

A vision setup that's flexible, allowing us to tailor to the specifics of your web, your substrate, and your line speed.

02

Hardware

The edge

State-of-the-art NVIDIA compute, on-prem in a rugged box wired straight to your line and the vision system.

03

Software

The platform

A browser-based live dashboard that allows you to view any line from anywhere, generate audit-ready report cards, and visualize predictive data.

04

Machine learning

The intelligence

A menu of large, custom-built models that allow us to find defects without a reference image across hundreds of SKUs.

We don’t sell you a camera and wish you luck. We manage the technology, so you get a smarter line, not more work.

The questions coil coaters actually ask.

Do we have to write a recipe every time a paint system or a defect changes?

No, and that is the core difference. When a new paint system, a new substrate or a new defect appears, retraining the model is our job, not a change order you write and pay for. You are never locked into editing recipes to keep inspection working.

Do you tell us where the defects are on the coil?

Yes. You get a defect map of the whole coil, every flaw located by footage and by position across the strip, so you know exactly where to cut around it at slitting, cut-to-length or roll forming, instead of scrapping good metal with bad.

Can Shelfmark run alongside or replace our current strip inspection?

Either. We can augment a system you already run or replace it. Because we mount our own cameras and run our own models, we are not dependent on your current vendor’s software or recipes.

Is this a capital purchase or a service?

A service. Instead of a large machine-vision system bought up front, you pay as an operating expense scoped to your coating lines, and tuning and upkeep are included, not billed per change.

What about false alarms and nuisance defects?

Deep-learning models are tuned to your real defects, not fixed thresholds, so the system learns the difference between a defect that matters and normal surface variation, and we keep tuning it as your paint systems and substrates change.

Will it keep up with our line speed and strip width?

Yes. We inspect at production speed across the full strip. Typical coil coating lines run 300 to 500 ft/min on strip up to 72 in wide, and the cameras and models scale from there. Inspection never becomes the bottleneck.

Do we own our inspection data?

Yes. Every coil stays on the record and is yours, queryable across lines and plants, exportable any time. The platform is the single source of truth for your quality data, not a black box.

What defects can Shelfmark catch on a coil coating line?

Coating voids and craters, dirt and seeds under the film, streaks and runs, orange peel and chatter, color and gloss drift, and scratches, dents and edge defects. Down to roughly 0.1 mm, across the full strip width, every foot of coil inspected in line.

What happens the moment a defect is found?

The floor is alerted immediately: an alarm at the line and the defect image on screen, tagged to the exact footage on the coil. Your operator decides what to do; nothing ships with a defect nobody saw.

How long does install take, and does the line stop?

A single line is typically instrumented and inspecting within days, not months. We mount cameras over the strip after the cure oven and ahead of the recoiler, calibrate to your line speed and width, and tune against your real defects. No teardown, and you never write a rule.
