Getting Your Heat Right in PET Blowing

If you’ve ever dealt with PET blow molding, you know the struggle. You need the preform to hit that perfect “glass transition” temperature fast—like, seconds fast—but if you push it too hard, you end up scorching the plastic. It’s a fine line. That’s why we stick with short-wave halogen infrared lamps. They pack a punch. They get the PET resin soft and ready to go almost instantly. Let’s talk power. Most of these setups run on 220V or 380V/400V, depending on what your machine’s power rail can handle. We usually see tubes ranging from 2000W to 3000W to keep things moving quickly. But here’s the thing: you’ve got to match your lamp’s voltage to your transformer exactly. If you over-volt them, you’ll burn through your bulbs in a matter of days. On the flip side, under-volting them just drags out your cycle times. And in this business, slow cycles mean you’re losing money. The build quality matters. We use high-purity quartz glass because it doesn’t freak out when the temperature swings wildly from hot to cold. Plus, a lot of our tubes have a special coating. Instead of letting heat bleed into the machine frame, it pushes the energy forward, right where it belongs: on the preform. For the connections, we use R7s or SK15 bases. They’re simple drop-in replacements for most standard ovens. They fit tight, too. You don’t want something wiggling loose while the production line is humming along at full speed. Real-world tweaks. The best part is how much control you get. You can actually mix and match wattages. Maybe you want more heat on the body of the bottle and a bit less on the neck so the walls don’t end up uneven. It lets you dial things in until they’re just right. Just a heads-up: these lamps getinsanely hot. If your cooling fans aren’t up to the task, that heat soak will eventually eat your wiring and connectors alive. It’s a trade-off. You get incredible heating speed, but you have to make sure your machine can breathe.
