Getting Your KHS Blow Molding Heat Right

Ever pull a batch of PET bottles off the line and notice some walls are thin while others are thick? It’s a headache. Usually, it comes down to uneven heating in your KHS machines. It happens all the time. Lamps get old, or someone swaps them out for cheap replacements that leave “cold spots” in the oven. When that happens, your bottles end up with structural weak points. Not great. To actually fix it, you need IR lamps that are built for the specific way KHS equipment breathes and heats. The science part (kept simple) Here is the thing: PET is picky. If the IR wavelength doesn’t hit the polymer’s absorption peak just right, you’re basically burning electricity for nothing. You end up scorching the surface of the preform while the core stays cold. We handle this by focusing on the filament positioning and using high-purity quartz. It keeps the heat field flat. No more random hot spots. The hardware side of things These are drop-in replacements. Whether your KHS model uses R7s or SK15 connectors, they just fit. You won’t have to mess around with your sockets or rewire anything. Just a heads-up: if you’re pushing high wattages to keep your cycle speeds up, your cooling fans are going to work harder. Check your ventilation. If your fans are clogged with dust, those high-output lamps will bake your reflectors and burn out way faster than they should. What this actually looks like on the floor When you switch to precision lamps, the “tweaking” stops. You get a much tighter temperature window and consistent softening every single time. That means way fewer rejects hitting the bin and less time spent fiddling with machine settings every time you change a bulb. We build these to take a beating. In a 24/7 production environment, you need filaments that don’t quit after a few thousand power cycles. These do the job.

Why getting the details right on your Sidel Matrix actually matters

When we build a PET infrared lamp, we don’t just copy what someone else is doing. We dig into how your Sidel Matrix actually behaves—electrically and thermally—so the replacement acts like the original. That way, you don’t have to retune the whole machine just to get back to normal. We match the original’s power density and how it responds to heat. Wattage, voltage, length—everything is chosen to recreate the same heat curve across the PET preform. Because if that curve shifts, you start seeing uneven stretch, weak necks, or crystallization. Keep the curve consistent, and the process stays steady.

White coating IR lamp for PET blowing

On the blow molding floor, unplanned stops and uneven preform heating cost you — in scrap, missed schedules, and overtime. When the heating tunnel isn’t pulling its weight, the whole line drags, and you’re constantly chasing lamp failures and temperature swings.

What actually matters, technically

The white-coating IR lamp we use for PET blowing is a short-wave infrared emitter built around a quartz envelope and a tungsten filament. It’s engineered to match the fast response and tight control that stretch blow molding demands. The white coating is there to shape the spectral output and boost reflectance inside the heating tunnel, so you get repeatable heating across the preform wall. We spec it to the power and mounting standards most blow molders run — R7s base options included — with voltages that line up with typical machine configurations. In practice, that means quicker ramp-up, stable zone temps, and fewer hot and cold spots.
