Let’s talk about the 960mm 1500W Halogen Lamp
If you’re running a blowing machine, you know the struggle. You need your PET preforms soft enough to shape, but you can’t just blast them with heat or you’ll end up with burnt surfaces and wasted plastic. That’s exactly why we built this lamp. At 960mm and 1500W, it’s all about that sweet spot. We wanted something that hits the plastic hard and fast, but stays uniform. Since the preform is rotating, the length of the tube ensures it gets a steady soak of radiation from every angle. A quick word of caution on the power. We landed on 1500W because it’s the best balance between getting the job done and making the lamp actually last. If you try to push too much wattage through a tube this size, you’re asking for hot spots. And hot spots warp quartz. Also, do yourself a favor: check your power supply. Voltage spikes are filament killers. Keep it stable, and these things will treat you right. Why halogen and quartz? Ever notice how some lamps get cloudy over time? That’s tungsten evaporating and sticking to the glass. We use a halogen cycle to stop that from happening. It keeps the glass crystal clear, which means your heat output stays consistent for thousands of hours. We wrapped it all in a quartz envelope to handle the intense heat of shortwave radiation. Plus, we used standard industrial connectors, so you can just pop these into your existing array without a headache. Getting the most out of them These lamps are workhorses, built for the non-stop grind of bottle production. Because they use shortwave IR, the heat sinks into the plastic almost instantly, which lets you speed up your cycle times. But here is the thing: the lamp is only half the battle. **Check your reflectors.**If they’re pitted, dirty, or just slightly crooked, you’re throwing away a huge chunk of that 1500W. When that happens, the temptation is to run the lamps hotter to compensate. Don’t do it. That just puts unnecessary stress on the filament and kills the lamp early. One last tip? Keep the quartz clean. A little bit of oil or dust might not seem like a big deal, but it bakes onto the surface. Once that happens, the thermal stress can actually crack the tube. Keep them clean, keep your voltage steady, and they’ll do the heavy lifting for you.
