Getting Your PET Blowing Right with Quartz Halogen Lamps

If you’re blowing PET bottles, you know the drill. You need a massive burst of heat to soften those preforms fast before they hit the mold. That’s where our quartz halogen infrared lamps come in. They push out shortwave radiation that cuts right through the plastic. These aren’t your average light bulbs—they’re heavy-duty heating tubes built to slide right into your industrial ovens without a fuss. The Power Stuff Here’s the thing: you’ve got to get your voltage and wattage exactly right. If they don’t match your power supply, you’re asking for trouble. Either the bulb will burn out way too early, or you just won’t get enough heat to do the job. These tubes pull a lot of power to get that plastic to its transition temperature in a matter of seconds. We use a quartz envelope because it can handle the stress of heating up and cooling down over and over again without cracking. What’s Under the Hood We use high-purity quartz glass for a reason. It keeps the tube from soaking up the heat itself, which means more energy actually hits the PET. Inside, there’s halogen gas that stops the tungsten from evaporating. This keeps the glass crystal clear and helps the lamp last a lot longer. Depending on your setup, you’ll probably need R7s or Sk15 bases. We make sure the fit is tight so you don’t get any nasty electrical arcing when the machine starts vibrating. Real-World Advice These lamps put out an incredible amount of heat. It’s great for your cycle times, but it’s tough on your reflectors. If your reflectors are dirty or pitted, the heat won’t spread evenly. That’s how you end up with thin walls in your bottles. And a pro tip:**keep your fingers off the glass.**Oils and fingerprints leave deposits that create hotspots. Those hotspots are what kill the quartz. Just keep them clean, wire them up according to the specs, and you’re good to go.

Let’s talk about the 355mm Quartz Halogen Heater

If you’re running a PET stretch blow molding line, you know the preheating stage is where the magic happens. That’s why we built these quartz halogen lamps. They basically take electricity and turn it into short-wave infrared heat, softening your PET preforms just enough so they’re ready to hit the mold. The power side of things We went with a 440V 2000W setup because it’s a powerhouse. By using 440V over that 355mm length, we can push 2kW of power without things getting unstable. It’s fast. Really fast. And that’s exactly what you need to get those preforms up to temperature quickly. But a word of caution: make sure your wiring can actually handle 440V. If it can’t, you’re looking at a premature burnout. Plus, if your voltage dips, your heat drops. That’s how you end up with bottles that have weird, uneven walls. Why quartz and halogen? The outer shell is high-purity quartz. We use this because it doesn’t freak out when the temperature swings wildly—it won’t crack under thermal shock. Inside, there’s a halogen cycle going on. It basically pushes the tungsten back onto the filament so it doesn’t thin out and snap too soon. Since the quartz is so clear, the infrared energy shoots straight through and hits the plastic. No wasted heat. Fitting them into your line These are designed to be simple drop-in replacements for most standard PET ovens. They get up to speed quickly, which is a lifesaver when you’re pushing for high-speed production. Just keep one thing in mind: 2000W in such a small space creates a lot of intense heat.**Check your cooling fans.**If they aren’t humming along perfectly, your lamp sockets could literally melt. If the air isn’t moving, the lamps won’t last. I’d also suggest popping the hood every few months to check the contact points for oxidation. Keep those connections tight, and you’ll be in good shape.

PET Blowing Machine 220V 1500W infrared halogen lamp

Introduction

We built this 220V, 1500W infrared halogen lamp for one job: PET blowing machines. It’s all about hitting the preform with heat that’s focused and easy to control, so you get even heating without pushing the material too far.

Power, Voltage, and Output: Keeping It Simple

The 220V rating isn’t random. It lines up with standard industrial power, so you can wire it in without needing extra transformers. And the 1500W? That’s a sweet spot. Enough punch to heat preforms fast, but not so much that you have to rework the whole electrical cabinet. It’s high power in a small package—exactly what the PET blowing process calls for.
