Getting Your PET Heating Right with 630mm Halogen Lamps
If you’ve ever dealt with PET bottle blowing, you know the struggle of getting the heat just right. That’s why we built our 630mm 800W halogen lamps. They use shortwave infrared, which is basically a fancy way of saying the heat hits the plastic fast. No waiting around for the air to warm up—it just works. The sweet spot for power We went with 800W over a 630mm length for a reason. It gives you a steady, controlled flow of heat. Ever seen a bottle with those annoying burnt spots or walls that are thin in some places and thick in others? That usually happens when your heat is uneven. These lamps fix that. They keep things consistent, which is a lifesaver when you’re running high-speed lines and every second counts. Built to actually last Here’s the cool part: we use a halogen cycle. Without it, the tungsten filament would just evaporate and gunk up the glass. By keeping the tube clear, the light gets through properly for thousands of hours. Plus, the quartz is tough. It can take a serious thermal shock without cracking. If you’re cranking out high volumes, you don’t want your lamps popping the second you flip the power switch. Fitting them into your setup These are pretty much “plug and play” for most standard PET oven arrays. The 630mm size fits right into the usual heater banks. But a quick tip: check your reflectors. If they’re oxidized or dirty, they’ll kill your efficiency. You’ll end up pushing the lamps harder than they need to go, which just wastes energy. One thing to watch out for… There is a trade-off. 800W of shortwave radiation puts out a lot of heat inside that oven housing. Make sure your cooling blowers are actually doing their job. If the airflow is blocked or the fans are too weak, you risk warping the oven frame or frying your wiring over time. Worst of all? Your lamps won’t last nearly as long. Keep them cool, and they’ll keep working.
