Stop Wasting Bottles During Start-Up

If you’re running Krones Contiforms or SACMI machines, you know the drill. Everything moves fast. When you’re cranking out thousands of bottles an hour, every second counts. The real headache? The start-up. Waiting for those infrared lamps to actually hit the right temperature is a drag, and it usually means a mountain of scrap bottles you have to purge before the line is actually dialed in.

Cutting the Lag

We wanted to fix that. We built these replacement lamps to kill the lag between hitting the “on” switch and getting full heat. In a rotary setup, the preform doesn’t hang around—it flies through the oven. If your lamp is too bulky or slow to warm up, the PET doesn’t hit that sweet spot (the glass transition temperature) evenly. To solve this, we tweaked the tungsten filament geometry and the thickness of the quartz. The result? The lamps hit operating temp way faster. It means fewer “cold” bottles in the bin and a much smoother start to your shift.

Krones preform reheating module

Out on the floor, a Krones blow molder is just sitting there, waiting on heat. Preforms hit the machine at the wrong temperature, the heating tunnel starts to drift, and suddenly you’re chasing rejects—thin walls, inconsistent stretch, or worse, a heater that jams up. Nobody needs another guessing game. You need a reheat module that keeps pace with the machine’s timing, follows its profile, and stays inside the tolerances. What actually matters, technically The Krones preform reheat module leans on short-wave infrared halogen emitters. They get to set temperature fast and recover quickly between shots, which is exactly what the cycle demands. We match emitter geometry and power density to the preform wall thickness and pitch, so the energy lands where it matters—shoulder and body—without scorching the neck finish. Output is tuned for a quick ramp and tight control. The module uses the same mounting, alignment, and wiring as the original, including the standard R7s lamp connections. Reflector geometry concentrates the pattern, so you waste less heat and keep the tunnel temperature even across the row. Why this works in stretch blow molding In stretch blow molding, repeatability is the only thing keeping OEE respectable. This module stabilizes preform temperature before the stretch, so thickness swings shrink and cycle-to-cycle variation drops off. The fast response shortens the heating window, which can shave seconds per cycle and cut down on gas pressure spikes. Energy use falls because the emitters deliver heat on demand, not full-time, and the focused pattern keeps losses low. Maintenance is simpler, too—lamp swaps are quick, and the build keeps heat away from nearby components, so you spend less time chasing thermal drift. The details you can’t skip Installation is straightforward, but it still comes down to the specifics. Confirm your machine voltage, connector type, and mounting dimensions. Expect a short warm-up and a recalibration after the first lamp change to lock the temperature profile in. Keep the reflectors clean—dust and bottle debris scatter the energy and force the control loop to work harder. Match emitter wattage to the preform material and color; heavy tints absorb differently and that shifts the heat balance.

Krones PET preform oven parts

On a Krones stretch blow molder, preform heating is the line’s balancing act. If the heating tunnel doesn’t pull its weight, you get uneven wall distribution, flash, and the reject rate starts climbing. If the lamps spike or drift, you spend the day chasing temperature and watching energy costs creep up. The fix starts with the right Krones PET preform oven parts—specifically, infrared emitters spec’d to the machine.
