Technical Specifications for 700mm 1200W Halogen Lamps in PET Blowing Applications

Let’s talk about our 700mm 1200W Halogen Heating Elements

If you’re running blowing machines, you know the struggle. You need to get those PET preforms soft enough to shape, and you need to do it fast—but without actually melting the plastic into a puddle. That’s exactly why we built these 700mm lamps. They aren’t your typical light bulbs. They’re short-wave infrared emitters designed to hit the plastic with exactly the right kind of heat. Getting the heat just right We set these at 230V and 1200W. Why? Because that specific balance across the 700mm length ensures the preform heats up evenly. Here’s the thing: if the wattage is too low, you’ll end up with bottles that have weird, uneven wall thickness. But if you push it too hard? You’ll scorch the material. It’s a delicate balance, and we’ve dialed it in for you. Built to take a beating These lamps live a hard life. They’re clicking on and off hundreds of times every single hour. To handle that kind of thermal shock, we use high-purity quartz glass to house the tungsten filament. Plus, the halogen cycle keeps the filament from evaporating too quickly. It basically buys you a lot more time before the lamp burns out and you have to swap it. One quick tip:**keep your reflectors clean.**If dust or carbon builds up, the heat doesn’t throw properly. That forces the lamp to run hotter than it should, and that’s a fast track to a dead bulb. Putting them to work These are designed to be simple drop-in replacements. We kept the dimensions tight so they slide right into your existing oven racks. No need to go hacking away at your chassis or modifying the frame. But, a word of caution. 1200W in a tube this size puts out a lot of ambient heat. Make sure your cooling fans and vents are actually doing their job. If that excess heat stays trapped near your electronic controllers, your lamp life is going to tank. And for the love of your equipment, make sure you’re plugged into a stable 230V source. Voltage spikes are brutal—they can snap a filament the second you flip the switch.
