Replacement lamp for Husky preform machine

Stop Overpaying for Your Krones Heating Lamps

Let’s be honest: OEM parts for Krones Contiform machines are expensive. Like, really expensive. It feels like you’re paying a premium just for the brand name on the box, while your overhead keeps climbing. We’ve got a better way. We make heating lamps that do the exact same job as the originals, but without the eye-watering price tag.

How it actually works

These aren’t your average lightbulbs. We’re talking shortwave infrared. We take a tungsten filament and wrap it in high-purity quartz to blast heat straight into the PET preform wall. Whether your oven runs on 230V or 400V, we push the wattage high enough to hit that glass transition temperature in a matter of seconds. If the heat is off—even by a little—you end up with uneven walls and bottles that just aren’t right. We make sure that doesn’t happen.

Husky preform molding IR radiator

On a Husky stretch blow molder, the heating tunnel is where the whole cycle hangs together. When preforms run uneven, you’re immediately chasing neck finish stability, stretch ratios, and wall distribution. If the IR output drifts or the emitter geometry is off relative to the machine’s focal line, you’re going to see scrap and unplanned stops.

What matters, technically

The Husky preform molding IR radiator is built around short-wave infrared in a quartz envelope, engineered to match the original OEM heating profile. Typical ratings are 2400–3600 W, 220–240 V, with R7s base termination for a direct fit. We hold filament geometry and reflector alignment to tight tolerances so energy density stays consistent across the preform wall. Output holds steady over thousands of hours, with field-reported life of 5,000+ hours and low lumen decay.
