Getting Your KHS Blow Molding Heat Actually Consistent

Ever pull a batch of PET bottles off the line and realize the walls are uneven? Some spots are thin, others are thick, and you’ve got structural weak points that just shouldn’t be there. If your preforms are hitting the mold with cold spots or a center that’s way too hot, it usually comes down to one thing: the IR lamps. Specifically, how they’re throwing heat.

The Trick to Even Heat

We don’t just make generic bulbs. We build our replacement IR lamps to fit the exact focal length and wattage that Krones and KHS ovens demand. Getting that “flat” thermal profile—where the heat is the same everywhere—is a bit of an art. It’s all about the filament winding and the thickness of the quartz. We obsess over the wattage-per-centimeter ratio. Here’s the catch: high-wattage tubes are great for speeding up your cycles. But if that filament isn’t centered perfectly? You get “hot stripes.” And those are a nightmare for bottle quality.
