Reducing Operational Costs in Can Oven Sealing via Infrared Radiator Retrofitting

Stop wasting money heating the air in your sealing lines

Let’s be honest: electricity bills for the sealing stage are usually a nightmare. Most plants are still using old-school heating elements that basically turn the entire oven into a giant space heater. You’re paying to warm up the air, the oven walls, and probably the rest of the factory floor. It’s a waste. The fix is actually pretty simple: switch to infrared (IR) radiators. Here is why it works. Traditional ovens rely on convection, which is sluggish. IR is different. It sends electromagnetic radiation straight to the can. We tune these lamps to a specific wavelength so the metal and the coating actually soak up the heat. It’s an instant hit. No more waiting around for the oven to “get up to temp.” That annoying thermal lag? Gone. When we’re picking out the hardware, we look closely at the wattage-to-length ratio. This is the secret sauce. High-density IR lamps let you shrink the size of your oven without losing any of the punch. We use quartz envelopes because they can handle the heat stress without flaking out on you. One quick heads-up on the electrical side: check your voltage before you start wiring. Moving to higher voltage lamps can drop your current draw, which takes some of the pressure off your electrical panels. But there’s a trade-off. More heat density means the lamps get hotter. If your ventilation is weak, you’ll burn through the lamp ends way faster than you should. Keep them cool, and they’ll last. At the end of the day, it comes down to the cost per ten thousand units. Installation is usually a breeze—mostly just drop-in replacements with standard connectors to keep your downtime to a minimum. You’ll notice the biggest difference if you’re running high-throughput lines where the ovens are constantly humming. Check your kWh per unit after the switch. The numbers usually speak for themselves.

Getting Your Can Lids Sealed Right (Without Slowing Down)

When you’re pushing 500 cans a minute, you don’t have time to wait around. You’ve got a tiny window—literally milliseconds—to get that lid to the right temperature so it seals tight. Standard heating elements just can’t keep up. They’re too sluggish. That’s why we use shortwave infrared lamps. Instead of warming up the air around the can, these lamps shoot energy directly into the metal. It’s instant. The timing is everything. At those speeds, the lid is barely under the heater before it’s gone. We set these lamps up for a near-instant response. Because the heat hits the surface immediately, the seaming tool can do its job and create a leak-proof joint without you having to touch the conveyor speed. If your lamps lag? You’re looking at inconsistent seals and a mountain of scrap metal. Nobody wants that. The nuts and bolts We pack a lot of wattage into a pretty small space. By using a shortwave quartz tube, we concentrate the heat right where it needs to be. One quick tip: keep an eye on your power supply. Factories are notorious for voltage spikes, and those can fry your filaments in a heartbeat. Make sure you’ve got decent regulation in place so you aren’t replacing bulbs every other week. Fitting them in The good news is these are basically drop-in replacements. They wire up fast and get you running quickly. But here’s the catch: this much energy in one spot creates a lot of heat. You can’t just slap them in and forget it. You need to be smart about your cooling fans and shielding. If the airflow isn’t right, you might find your mounting brackets warping or your sensors acting up because they’re overheating. It’s all about balance. If you go too heavy on the wattage, you’re just wasting power and killing the life of the lamp. But if you go too light, you’ll never hit that 500 CPM mark without risking a leak. Get the wattage matched to your line speed, and you’re golden.

Stop Throwing Away Your First Batch of Cans

If you’ve ever run a beer can line, you know the headache of the “warm-up.” You flip the switch, wait for the heaters to get up to temp, and then—inevitably—the first few dozen cans are scrap. The internal coating just didn’t set in time, the seal isn’t tight, and you’re tossing good aluminum into the bin before the shift has even really started. It’s a waste of time and a waste of money. Here is how we fix it.
