oem odm infrared halogen heat lamp for pet bottle blowing

May 25, 2026

We build infrared halogen heat lamps specifically for PET bottle blowing—OEM and ODM, tailored to the real work on the floor. These aren’t general-purpose heaters. They’re built to blast high-density radiant energy exactly where the preform needs it, and nowhere else. Here’s the power setup, in plain terms. Most units run 400V at 2500W, in either a 300mm or 600mm tube. Why? Because 400V lets you push serious wattage without overloading the wiring, so you don’t end up with bulky conductors. And 2500W packed into that compact length gives you the fast ramp-up PET heating cycles demand. That intensity comes with a trade-off. You get focused, rapid heat—but your machine’s cooling needs to be up to the job. Plan for the ambient heat rise around the lamp, and everything stays solid. The body is quartz, plain and simple. It handles thermal shock and stays stable at high temps, which is exactly what this job requires. Inside, the halogen cycle keeps the filament clean, so output stays consistent over the life of the tube. We add a reflective coating to steer the energy forward. Less stray radiation. More useful heat hitting the preform. And the connectors—R7s or SK15—are chosen for a secure, high-temp fit. Mechanical and electrical, both. The payoff? When it’s time for maintenance, it’s a drop-in replacement. No rewiring the whole heater block. Just swap and get back to work. On the line, these lamps target the preform wall and heat it quickly and evenly. That consistency is what makes stretch and blow performance predictable. The infrared spectrum gets into the PET surface without scorching it, while still hitting the internal temperature profile you need. The heat footprint is tight, so you’re not wasting energy. And the rugged quartz envelope keeps taking the thermal cycling of continuous production. For engineers, that means heating you can count on, cycle times that move, and fewer rejects born from uneven heat.
