650mm 220v 660w Halogen Lamp Replacement Parts for Bottle Blowing

Let’s talk about the 650mm Halogen Heater for PET Blowing

If you’re running PET bottle blowing machines, you know the heating oven is where the magic—or the nightmare—happens. We built these 650mm halogen lamps to make sure it’s the former. At 220V and 660W, these tubes hit that sweet spot. They use shortwave infrared radiation to dive deep into the PET preform, softening the plastic from the inside out. It’s fast. Efficient. And it keeps the surface from getting scorched. The deal with power and size The 650mm length is a standard fit for most medium-to-large ovens, so you aren’t fighting with the installation. But the 660W part? That’s the important bit. You need that specific punch of heat to get the plastic to its glass transition temperature exactly when it needs to be there. If the wattage is too low, the plastic stays stubborn and cold. That’s how you end up with “pearling” or walls that are thin in some spots and thick in others. Nobody wants to scrap a whole batch of bottles because the heat was off. Why quartz actually matters We house the halogen cycle in high-purity quartz glass. Why? Because it stops the tungsten filament from evaporating. Without it, your tubes would blacken and burn out way too fast. The quartz lets the IR energy fly straight through without soaking it up. Plus, we use standard end-caps. You just pop them in, and they work. No fuss. Real-world advice Look, these lamps are tough, but they aren’t invincible. They live in a brutal, high-heat environment. Here is a pro tip:Keep your reflectors clean. If your reflectors are covered in dust, your 660W lamp is basically fighting a losing battle. It has to run longer to do its job, which kills the filament. And please, keep an eye on your cooling fans. These things run hot. If the airflow dies, you’re looking at stressed quartz or melted sockets. Keep the air moving, and these lamps will treat you right.
