Molding on Quartz IR Point Heating

Krones blow molding infrared solution

Out on the plant floor, a Krones blow molder running hot puts the heat on every preform. They’ve got to hit the right temperature profile before stretch blow molding. If the heating tunnel starts underperforming, the PET comes out too stiff or too soft, and the machine spends the whole shift chasing rejects. We built the Krones blow molding infrared solution to break that cycle.

What matters technically

We spec the Krones blow molding machines with short-wave infrared emitters and quartz heating elements matched to the OEM thermal curves. The emitters run on standard line voltage, drop in with R7s bases, and mount the way the machine expects—so you can swap them into the existing holders without rewiring the heating tunnel. Power density is tuned for PET preform heating: fast response, tight control, and consistent output across the cavity bank.

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.
