SIPA Preform Heating Lamp: The Secret Weapon for Perfect PET Bottles
We built this SIPA preform heating lamp for the wholesale crowd. Same quality we send to the big brands—now it’s ready to roll right onto your shop floor. Its mission? Keep things rock-solid. Deliver intense, even heat to your preforms so every bottle comes out with a smooth, consistent wall. Less scrap. More peace of mind.
Power, Voltage, and Size—Why It Matters
Here’s the heart of it: a 400V high-voltage design, cranking out 2500W of heat inside a 300mm tube. That 400V setup is smart. It pulls less current than the lower-voltage options, so your wiring stays cooler and you don’t lose power over distance. And that 2500W packed into a 300mm space? It means your preforms hit the target temperature fast. Really fast. That speed keeps your line moving, but it also means one thing: your machine’s cooling has to be up to the task. Keep that airflow sorted, and you’re golden.
The Details That Make a Difference
Inside, we use a halogen element in a quartz tube. Why? Because it keeps the heat steady, even when you’re cycling temperatures again and again. The coating on the tube keeps the heat focused where it needs to be. More efficiency, less stray heat that could mess with nearby parts. And the R7s connector? It’s all about simplicity. Easy to wire, built to handle swap after swap on a busy line. When a lamp burns out, you’re back up and running in no time.
Built for the Real World
Out on the PET blowing line, this lamp brings the heat—literally. It gives you the density you need to warm preforms evenly, so the stretch and blow happen the same way, every time. It can take the heat, the vibration, the dust—and still keep its cool. For wholesale buyers, the combo of 400V efficiency, 2500W power, and the 300mm footprint means one lamp can fit across multiple machines. Less inventory to juggle. Less maintenance headache. Just remember: with this kind of power, you’ve got to plan your airflow and reflector setup to keep everything running safely. Do that, and you’ve got a tough, practical lamp that just gets the job done.
