Getting the Heat Right on Beverage Can Lugs

When you’re dealing with anti-corrosion coatings on a pull-tab, you don’t have much room for error. You’re talking about micron-level zones. If you miss the mark, you’re either leaving the coating uncured or, worse, you’re overheating the aluminum and ruining the can. It’s a delicate balance.

Hitting the Sweet Spot

To get that kind of precision, we stick with short-wave infrared emitters. Think of it like a laser instead of a floodlight. It lets us concentrate the energy into a tight beam that hits the coating without bleeding heat into the rest of the can. Speed is the other challenge. Your line is moving fast, so we pump up the wattage density to make sure that coating cures the second it passes through. But you can’t just crank the dial to ten—do that, and you’ll warp the lug. We spend a lot of time tweaking the power against your conveyor speed until we find that perfect thermal equilibrium where everything just works.
