Corona pre-treatment station for coating adhesion
A conveyor-type treatment station for metal panels that paint wouldn't stick to. This is the story of the build — from problem statement to tested machine.

What we build, and how we think.
Customer case studies are being documented and will be published as they are cleared for sharing. What we can show you today, honestly, is our reference build — the flagship corona pre-treatment station — told the way we actually worked through it.
Reference Build · In-House Flagship
The requirement
It arrived the way most requirements do: not as a machine specification, but as a process problem — coatings not anchoring properly on metal panels, and no standard treater that fit the panel size and line. The starting material was a description of the problem and the panels themselves.
The engineering decisions
Three decisions shaped the design: a conveyorized mesh-belt path so panels move through the treatment zone hands-free; an adjustable dielectric electrode assembly so treatment width and gap can be set per panel; and our own 3 kW-class high-voltage module, so electrode and power stage are one matched electrical system.
The build
Aluminum extrusion frame with leveling feet for uneven floors. Stainless mesh belt. Electrode assembly on an adjustable acrylic mount. Controls that interlock with the line, so treatment only runs when panels run. Designed in CAD, approved, then fabricated and assembled on our floor.
The test
Every unit runs before it ships — this one included. Functional run against the agreed criteria, with video acceptance available for remote FAT. You see it treat panels before it leaves, not after it arrives.
What this build proves
That "custom" here is a method: a production problem, a CAD model you approve, a machine you can watch run before shipment. Your panels, coating system, and throughput would change the dimensions — not the method. That's why this build is a starting point, not a ceiling.
More references coming
Customer projects — including hot-cutting knife deployments in film and bag lines — are being written up with the same engineering structure and will be published as they are cleared for sharing.
