What This Lamp Actually Does
Think of the carbon blowing machine fiber lamp as the workhorse of the plastics shop. It’s a purpose-built infrared heater, designed to get PET preforms and parisons warmed up fast before the blowing step. We built it to deliver intense, focused heat right where the process needs it.
Power, Voltage, and Size—Kept Real
These lamps typically run on 400V, pulling the current needed for serious power—often around 2500W—packed into a 300mm tube. That’s how you get high heat density in a small space. The result? The polymer heats up quickly, without turning the rest of the machine into a sauna. The short form keeps it nimble, fitting into tight necks and tooling without a fight.
The Materials That Make It Tick
Inside, you’ve got a halogen-filled quartz envelope. Quartz is great because it responds instantly and shrugs off thermal shock. It lets shortwave infrared energy through with almost no fuss, and the halogen cycle keeps the filament stable, which helps the lamp last. Then there’s the R7s bi-pin connector. It gives you a solid, low-resistance electrical link—handles the high current and makes the lamp a simple drop-in when it’s time for maintenance. No drama, just a clean swap.
How It Performs on the Line
On carbon blowing lines, this lamp heats the parison evenly, so bottle wall thickness stays consistent. That focused heat profile helps shorten the cycle time. Now, the trade-off is real: with that much power density, your machine needs proper cooling and shielding to keep nearby parts safe. But when the lamp is aligned and the reflector is kept clean, you get performance you can count on—day after day.
