Mercury UV Lamps for Plastic Bottles: Heat, Right Where You Need It
We build mercury UV lamps for one place: the plastic bottle line. They’re all about delivering intense, focused heat for pre-heating and stabilizing bottles. The point is simple: give your process the thermal punch it needs so your cycle stays fast and your output stays steady.
The power behind the heat
At the heart is the mercury vapor arc—engineered to crank out high-intensity UV and infrared. These lamps run at high voltage, usually 400V, to push that arc with serious power density. And the wattage is matched to the size. A standard 300mm tube often runs at 2500W. That’s a lot of heat packed into a small footprint. But here’s the thing: that kind of power comes with a trade-off. The lamp runs hot, so your machine’s cooling needs to be up to the job. If the surrounding temperature isn’t managed, you can start pushing both the lamp and nearby parts into thermal stress.
Built to take the heat
We use a high-purity quartz envelope. It handles the shock of rapid on/off cycling and lets the UV spectrum through cleanly. Inside, the coating is designed to keep the spectral output stable over the lamp’s life—so the heating performance stays consistent. On the practical side, the R7s connector makes installation straightforward. It gives you a secure, two-contact connection that can handle high current without getting hot itself. That means the lamp drops in clean, and your downtime stays minimal.
Why this matters on the shop floor
In bottle production, the lamp covers the thermal steps right before blow molding. The intense, controlled heat helps you hit the right temperature on the PET preform—and that matters for how the material distributes and how strong the bottle ends up. The heat stays focused where you want it, so you get fewer issues from uneven heating. For your team, that translates into fewer burnouts, easier maintenance, and a process that feels stable. We build these lamps to take the pounding of 24/7 production—so you can keep your head down and run the line.
