Drying Your Can Seals: IR vs. Induction

If you’ve got water hanging around the sealing zone of a can, you’ve got a problem. It’s a recipe for rust and bacteria, and neither of those belong in your product. To fix it, you basically have two options: induction heating or infrared (IR) lamps. Here is the real-world difference. Induction is great at heating up the metal itself. It gets the can wall hot, and it does it fast. But there’s a catch. It’s a bulk heating process. It doesn’t really “see” the water droplets sitting on the surface; it just cares about the metal. That’s where shortwave IR lamps come in. Think of IR as a targeted strike. The radiation hits those water droplets directly, turning them into vapor almost instantly. By the time the seam is actually crimped, the area is bone-dry. It just works. Plus, there’s the hygiene side of things. In a food plant, the last thing you want is oil or weird conductive fluids leaking onto your line. IR lamps are completely non-contact. We tuck them away in quartz sleeves or stainless steel housings, so nothing ever actually touches the can. No touch, no cross-contamination. Simple. Induction is a bit more finicky. You have to get the coil positioning exactly right. If a coil shifts even a little, you end up with hotspots. IR is much more forgiving—it gives you a wider, more even heat footprint. Now, I’ll be honest: IR isn’t a magic fix for everything. Those high-wattage lamps put out a lot of heat. If you don’t set up your ventilation or cooling fans correctly, you’re going to end up cooking your own electronics. You have to plan for that. So, if you just need the metal to be hot, induction is fine. But if your goal is to kill the moisture and keep things sterile? Go with IR. It’s the only way to be sure that sealing zone is totally dry before the lid drops.

Solving Can Lid Bloating via Infrared Thermal Uniformity in Gasket Curing

Why Your Can Lids Are Bloating (And How to Fix It)

If you’re seeing bloated can lids, you already know the deal: your seal is failing. Usually, it comes down to the gaskets. If they don’t soften up enough to create that vacuum-tight bond, air gets in. The real culprit? Your IR lamps are likely throwing out an uneven heat field. If the center of the lid is baking while the edges stay chilly, that gasket isn’t going to cure the way it should. The heat has to be flat. That’s the secret. You want a thermal profile that’s consistent across the whole surface. We use shortwave infrared emitters because they punch through the gasket material fast. You want that rapid soften—but you can’t scorch the coating. Here’s the thing: “hot spots” are the enemy. They create tiny micro-gaps. You can’t see them, but air finds them. That’s how you end up with bloated cans sitting in your warehouse. Getting the heat right It’s all about how those radiation cones overlap. If you tweak the spacing of the emitters and adjust how far they sit from the conveyor, those annoying cold zones just disappear. Now, high-wattage quartz tubes are great for keeping the line moving fast, but you have to balance that power with how long the lids actually spend under the lamps. If you just crank the power to 100% to fix a cold spot on the edge, you’ll probably burn the center of your lids to a crisp. The trade-off Getting that perfect, uniform heat usually costs a bit more in energy. Instead of running one lamp at full blast, we find it works better to run a few lamps at a lower percentage. It’s a smarter way to do it. Not only does it kill the hotspots, but it also stops your filaments from burning out prematurely. Just make sure your power supply can handle the extra load of a multi-lamp setup so your output stays steady all shift long. When the heat is flat, the gaskets soften evenly. The seal bites hard. And the bloating finally stops.

Integrating High Density IR Preheating Lamps into Compact Mobile Can Seamers

Squeezing High-Density IR Heat into Mobile Can Seamers

Trying to fit a high-performance IR preheating system into a mobile, small-shop machine is basically a giant game of Tetris. When your footprint is that tight, you just can’t afford bulky heating elements. That’s why we go with short-wave infrared lamps. They give you the heat density you need for a perfect seam without eating up half your workspace. The struggle with heat and space In a mobile setup, you can’t be sitting around waiting for a machine to warm up. We use IR lamps that hit peak temp in seconds. By focusing all that energy into a narrow quartz tube, the heat goes exactly where it belongs—on the can rim—instead of bleeding into the rest of the machine frame. But here’s the catch: if you crank the wattage too high in a closed box, you’ll fry your wiring. It’s a balancing act. You need enough power to get the job done, but you’ve got to have active ventilation to keep your control board from melting. The nuts and bolts We stick with quartz halogen tubes. Why? Because quartz handles thermal shock way better than glass. To make these a breeze to install in different mobile frames, we use standard connectors like R7s or Sk15. It means if a tube burns out, you can swap it in a couple of minutes. No need to rip apart the whole electrical panel. Plus, we often add a specific coating to the quartz. This stops the heat from just bouncing off the metal and actually forces it to penetrate the surface. Making it work in the real world Wiring these into a mobile unit takes a bit of care. Small workshops often have messy power with voltage spikes that can snap an IR filament in a heartbeat. To fix that, we pair the lamps with an SCR power controller. It lets you dial in the heat depending on what you’re canning. Aluminum and tin-plated steel don’t react the same way, so you need that flexibility. Just keep in mind that this kind of intense heat comes with a trade-off. If you run them at 100% all the time, those filaments are going to wear out faster. It’s just the nature of the beast.

Using Infrared Preheaters to Eliminate Residual Moisture in Milk Powder Can Sealing

Getting the Moisture Out of Milk Powder Cans

Here’s the deal: if there’s even a tiny bit of moisture left on the sealing rim of a milk powder can, you’ve got a problem. When that water gets trapped during crimping, it’s basically an open invitation for bacteria to move in or for the powder to spoil way too early. To stop that from happening, we use infrared (IR) preheaters to flash-dry the rim right before the can hits the seamer.

Using Infrared Curing Lamps to Eliminate Moisture in Can Seaming Zones

Stop Trapping Water in Your Can Seals

If you’ve got moisture hanging around the seaming area of a can, you’ve got a problem. It’s a recipe for contamination or, even worse, a seal that just fails. To fix this, we use short-wave infrared (IR) curing lamps to basically flash-evaporate those tiny water droplets right before the seal locks in. It’s more than just drying things off. It’s about building a wall against bacteria.

Eliminating Can Bloating Through Infrared Heat Field Uniformity in Lacquer Drying

Stop the Bloat: Getting Your IR Heat Right

Ever pull a batch of cans and see them bloating? It’s a nightmare. Usually, it comes down to a bad seal. If those gaskets don’t soften up enough during curing, you’re going to get leaks. Most people think they just need more power—more wattage. But that’s rarely the actual problem. The real culprit is usually “cold spots” in your IR array. When parts of the lacquer don’t get enough heat, the gaskets stay hard, and the seal fails.
