Getting Your PET Preforms Just Right: The 362mm 800W Halogen Lamp

If you’ve ever run a PET blowing machine, you know the struggle. You need that preform softened perfectly—not too cold, not scorched—before it hits the mold. That’s exactly why we built our 362mm 800W halogen lamps. They’re designed to slide right into your existing ovens without any fuss. The sweet spot for heat Here’s the thing about the 800W rating. It’s not just a random number; it’s the specific amount of energy needed to get PET to its glass transition temperature without burning the plastic. We use a focused halogen cycle to keep the tungsten filament from evaporating too fast. This means your light output stays steady for a long time. Just a heads-up: don’t try to push these lamps with a higher voltage than they’re rated for. If you do, you’ll burn out the filament way sooner than you should. Built for the grind We used high-purity quartz glass for the tubes. Why? Because these lamps are constantly clicking on and off as preforms move through the oven. That kind of thermal shock would crack cheaper glass. Plus, we kept the connectors standard. You can just wire them up to your current sockets and get back to work. We also added a halogen gas fill so the inside of the tube doesn’t turn dark over time. That way, the infrared heat actually hits the plastic instead of getting trapped in the glass. Real-world tips for your line These are shortwave emitters, so they heat the surface of the plastic almost instantly. It’s fast. Really fast. But to get the most out of them, keep your oven reflectors clean. If they’re oxidized or dirty, you’re basically throwing away a chunk of that 800W output. One last thing to watch out for: these lamps put out a lot of ambient heat. Make sure your cooling fans are up to the task. You don’t want a full bank of 800W tubes baking your machine’s electronics.
