Getting Your PET Preforms Just Right with 650mm Halogen Lamps
If you’re running a bottle blowing line, you know the struggle. You need that PET preform to soften up fast, and you need it to happen evenly. That’s exactly why we built our 650mm 1500W halogen infrared lamps. Instead of wasting energy heating up the air inside your oven, these lamps shoot shortwave heat straight into the plastic. It’s direct. It’s fast. And it saves you a lot of wasted power. Let’s talk power. We went with 1500W over a 650mm length because that’s the sweet spot for getting resin to its glass transition temperature in a matter of seconds. But here is a quick heads-up:check your power supply before you plug these in. If your oven isn’t built for this kind of wattage, you’re looking at a blown fuse or a tripped circuit. It’s a simple check, but it saves a huge headache later. Why quartz and halogen? Ever noticed how some lamps get that weird dark film on the glass over time? That’s the tungsten filament evaporating. We use a halogen cycle inside a quartz envelope to stop that from happening. The result? The glass stays clear and your power stays consistent. Plus, quartz is tough. It can handle the constant “on-off-on” thermal shock of a fast-moving production line without cracking. We also use standard industrial connectors, so you can just swap them out without needing a degree in engineering. Keeping things running smooth When these lamps are in your oven, they’re doing the heavy lifting to make sure your plastic is melted evenly. Because the heat penetrates deep into the plastic, you don’t end up with those annoying thin spots in your bottles. One last thing—these lamps gethot. Really hot. If your cooling fans are clogged with dust or just aren’t pulling enough air, that heat starts creeping back into the lamp ends. That’s a one-way ticket to burnt-out electrodes. Keep your airflow clean, and these lamps will last you a long time.
