OUR CORONA TREATERS
A Treater for Every Application
From narrow web label presses to wide-web film extrusion lines, every QC corona treater is custom-configured for your exact substrate, line speed, and production environment.
MOST POPULAR
Advantage Bare Roll
The workhorse of converting. Treats both conductive and nonconductive substrates with unmatched power density. The only bare roll treater with patented zero carbon tracking.
ConvertingPrintingCoatingLaminating
FILM EXTRUSION
TNT Covered Roll
Patented design for blown and cast film lines. Delivers high-efficiency treatment on nonconductive substrates with minimal heat transfer to your film.
Blown FilmCast FilmPatented
PRINTING & LABELS
Narrow Web
Compact, high-power treater purpose-built for flexographic and digital label presses. Drops into any narrow web line with zero modification.

R&D
DocuDyne Lab
The only benchtop treater that replicates production-scale watt densities. Validate treatment parameters in your lab before committing to full-line equipment.
LaboratoryScale-UpTesting
SHEET FORMAT
Advantage Sheetfed
Uniform treatment across the full sheet width for rigid and semi-rigid materials. Eliminates edge-to-edge variation that causes downstream adhesion problems.
SheetfedFull-WidthRigid
SPECIALTY
Vacuum Table
Precision treatment for ultra-thin and delicate substrates. Vacuum hold-down ensures consistent substrate contact with no duty cycle limitations.

INTELLIGENT CONTROLS
Complete Control at Your Fingertips
Our intuitive touchscreen interface gives your operators real-time visibility and precision control over every aspect of the treatment process. No guesswork. No manual adjustments. Just consistent, repeatable results.
Real-Time Monitoring
Live watt density, line speed, and treatment status displayed at a glance.
Recipe Storage
Save and recall treatment presets for every substrate — one tap to switch jobs.
Auto Gap Adjustment
Electrode gap adjusts automatically to maintain optimal treatment across your full web width.
Data Logging
Production data captured and stored for quality reporting, traceability, and process optimization.
Fault Alerts
Instant alarm notifications with diagnostic codes — identify and resolve issues before they stop your line.
Operator Lockout
Restrict access to critical settings so only authorized personnel can modify treatment parameters.

BEYOND THE EQUIPMENT
Support that Comes Standard
Every QC corona treater comes backed by direct factory support, the world’s largest electrode inventory, and engineers who answer the phone.
Free Lab Testing
Ship us your substrate. We’ll run it through our treaters, measure dyne levels, and send you a detailed report with recommended parameters—before you invest in equipment.
Fastest Electrode Shipping
World’s largest inventory of stock ceramic electrodes compatible with QC and all major OEM brands. Ship within 3 business days.
Direct Factory Support
No call centers, no third-party reps. When you call QC, you talk to the engineers who designed and built your treater. Phone, email, or on-site—we’re here.

Why Manufacturers Switch to QC
“
We needed ceramic electrodes for a treater that wasn’t even a QC system. OEM quoted us 8 weeks. We couldn’t wait that long. Called QC and we were back up within the week.

Flexible Packaging Converter
“
Our previous treater was going down every 6-8 weeks. We’ve been running the TNT for 14 months straight on our blown PE line with no unplanned downtime.

When I call QC, I talk to an engineer who knows my system. We had a power supply question on a Saturday and got a call back within the hour. Try that with the big guys.
