Mercury UV Lamps for Plastic Bottle Manufacturing: The Specs You Need for Branded, Heat-Controlled Production
Let’s talk about keeping your plastic bottle line running smooth. If you’re working with PET preforms and parisons, you know how crucial the right heat is. The kind that keeps things consistent, shot after shot. Our mercury UV lamps are built for exactly that—giving you precise thermal control so your blowing process stays stable and your output doesn’t skip a beat.
Power, Voltage, and Size: The Details That Matter
We don’t build these for guesswork. We build them for repeatable heat, every single time. The core setup? A mercury UV source running on 400V, delivering 2500W of power. That gives you serious heat density, packed into a surprisingly compact size. The 300mm tube length is intentional too—it fits right into the heating zones of most blow-molding cells. So you can swap it in without reworking your reflector housing. But here’s the thing: that kind of power needs the right support. Make sure your electrical setup can handle it, and your cooling is up to the task. If the airflow in your cabinet falls short, the lamp runs hotter—and your output starts to drift.
What It’s Built From: Quartz, Coating, and a Connector That Won’t Quit
The tube itself is quartz. Why? Because it handles sudden temperature swings like a champ, and it keeps that UV transmission steady—even when your machine is cycling on and off all day. We also use a specialized coating that helps control the output spectrum and keeps the operating temperature stable. No more hot spots that leave you with uneven heating on the parison. And the connector? It’s an R7s. Rugged, reliable, and built for high-temp runs. It makes wiring quick and secure, and holds its alignment even in tight reflector housings. No more worrying about arcing or connections that flicker during production.
Real-World Performance: Heat You Can Rely On
When you’re blowing PET, the lamp has one job: deliver uniform heat fast, so the material stretches the way it should. Our mercury UV design nails that. It responds quickly and holds a stable output across the entire tube length. That means fewer scrapped parts due to temperature swings—something that quietly eats into your margins. For wholesale buyers and brand owners, we also offer an OEM program. You get the same engineering, just under your label. Just keep in mind: that higher wattage gives you faster heat-up, which is great. But it also means your cooling and electrical layout need to be planned properly—so your components don’t get pushed past their limits.
