Getting Your PET Heating Just Right: The 500mm 1000W Halogen
If you’ve ever worked with PET blowing machines, you know the struggle. You need the plastic soft enough to shape, but the second you overdo it, you’ve got scorched preforms and a lot of wasted material. It’s a delicate balance. That’s why we built these 500mm 1000W halogen lamps. They’re designed to slide right into your current setup without any fuss. The Sweet Spot for Heat Here is the thing about power: it’s all about the spread. By pairing 1000W with a 500mm length, we’ve hit a balance that keeps the heat even across the whole surface. If you push too much wattage into a space this size, you get hot spots. And hot spots mean your bottle walls end up uneven. With this setup, you get that infrared punch needed to hit the glass transition temperature fast, but without the risk of ruining the plastic. What’s Actually Inside We use a halogen cycle inside a quartz envelope. In plain English? It stops the tungsten from evaporating. This keeps the filament exactly where it should be, so your heat output doesn’t drift over time. The best part is the response time. These aren’t like those sluggish heaters that take forever to warm up. They react almost instantly to voltage changes. If you need to tweak your heating zones on the fly, you can just do it. And since we used quartz, these bulbs can handle being switched on and off constantly without cracking from the thermal shock. Plus, we stuck with standard industrial connectors. You just plug them in and get back to work. A Few Things to Keep in Mind These lamps are powerful. They put out concentrated short-wave radiation, which is great for speed, but it means you have to stay on top of maintenance. Keep your reflectors clean. Seriously. A bit of dust or a smudge of oil can mess up your heat distribution and might even kill the lamp early. Also, remember that a bunch of 1000W units packed together creates a lot of heat. Just make sure your cooling fans are up to the task so things don’t get too toasted in there.
