Introduction
Ever had that sinking feeling when your KHS blow molder starts acting up? You trace the headache back, and sure enough, it’s the heating lamp. We built a replacement lamp specifically for KHS machines to get that heat performance back where it should be. This isn’t just some off-the-shelf bulb. It’s a precision-built piece, made to drop right in and spread steady heat across the entire preform zone.
The Details, Without the Fluff
It runs on 400V because that’s what these industrial machines need. That voltage lets the lamp pack a lot of heat into a small space—so you get serious power without having to rework the machine. And the length? It’s engineered to match the standard heating chamber. If you go shorter or longer, you’ll start seeing hot spots and cold spots. So getting the length right isn’t a “nice-to-have”—it’s essential.
What It’s Made Of
Inside, you’ve got a high-purity quartz tube with a halogen fill. The halogen chemistry keeps the filament stable even when things get scorching, so the output stays consistent over time. The quartz also has a special coating that reflects infrared energy back onto the preforms—more heat where you need it, less wasted into the machine frame. The connector end uses an R7s base, chosen because it makes solid contact and can handle high current without getting itself into trouble. Installation? Straightforward. Line it up, seat it, wire it, and you’re good.
What It Does for You
If you’re running PET preforms on a KHS blow molder, this lamp tackles uneven heating head-on. The coating and halogen design help even out the thermal field across the heating bands. Because it delivers high heat density, you can heat faster through the cycle. But—and this matters—your cooling system needs to be in shape. If the cooling is undersized or clogged, the lamp will run hotter than it should, and its life will shorten. Think of it as a matched set: lamp, voltage, and cooling. The payoff? Predictable heating, fewer temperature swings, and less scrap from inconsistent bottle weight. It’s built as a direct drop-in replacement, so you can spec it, install it, and get back to running.
A Straight-Up Reality Check
A 400V high-power lamp throws off a lot of heat, and that heat has to go somewhere. Make sure your blower airflow and heat sinking are up to spec. Otherwise, you’ll swap uneven heating for a lamp that burns out way too soon.
