Stop Fighting with Hot Spots in Your KHS Blow Molding Lines

Ever pull a PET bottle off the line and see that annoying pearlescence or a wall that’s way too thin in one spot? It’s frustrating. Usually, it comes down to one thing: your preforms aren’t heating evenly. When the heat is all over the place, you get structural weak points, and suddenly your scrap rate starts climbing. We got tired of seeing this happen, so we built a drop-in replacement quartz lamp that actually fixes those stubborn hot and cold spots.

Replacement lamp for SMI blow molding

Stop Letting OEMs Hold Your Blow Molding Heat Hostage

Let’s be honest: most blow molding OEMs love to lock you in. They use proprietary lamp specs for one reason—to make sure you have to buy replacements from them, regardless of the price or lead time. It’s a frustrating cycle. We decided to break that. We built our infrared lamps to ignore those restrictions. By sticking to a standardized footprint and electrical tolerance, we made a lamp that just works. Whether you’re running SMI machines or almost anything else on the global market, these are designed to slide right in.

Infrared lamp 400V 2000W blow molding

On the blow molder, uneven preform heating isn’t just a quality headache—it’s a countdown to downtime. When the heating tunnel starts fighting you, you end up with wall thickness that drifts, bottles that blow out, and resin that walks straight into the scrap bin. What you need is an infrared emitter that meets the original spec, drops in without rewiring, and holds steady output shift after shift. What matters under the hood We build this 400V, 2000W infrared lamp as a direct-fit for the heating zones on common blow molding machines. The quartz tube comes up fast and lays down even radiant heat, with wavelength output tuned for PET preform heating. It runs on 400V, pulls 2000W, and uses standard R7s connectors, so you can swap it in without touching the socket or bracket. Filament layout and reflector geometry are matched to the OEM heating profile, so temperature distribution across the tunnel stays repeatable. Why it holds up in stretch blow molding In stretch blow molding, the heating window is tight: you need a quick, controllable rise without scorching the preform. This lamp lands in that window with stable output, so you see fewer rejects and more consistent bottle weight. Because it’s OEM-matched, you skip the trial-and-error tuning and get back to running the job the way it was designed. You get OEM-grade heating performance, priced the way direct manufacturing allows—no brand premium baked in. A few shop-floor details Match the lamp to your machine’s voltage and mounting dimensions. Double-check the R7s connector type and make sure the reflector shape lines up with your heating tunnel. Expect a slightly longer warm-up ramp than a halogen unit; plan your changeover around that. Keep the lamp clean and aligned, and keep an eye on the heating-zone thermocouples so you don’t overshoot.

Teflon wire for blow molding heater

On a fast-moving Sidel or Krones blow molder, the heating tunnel is where the pressure hits first. One emitter goes down, the line stops, preforms cool off, and you lose output. Standard heaters have a habit of cracking, losing output, or shorting at the terminals. We built our Teflon-wire infrared heaters to fix those weak spots and give you repeatable performance, day after day.

What actually matters on the spec sheet

We run high-purity quartz tubes with tungsten filaments, tuned for short-wave infrared so you get fast response and tight temperature control. Inside, the wiring is Teflon-insulated for high dielectric strength and heat resistance, so the connections stay solid even when that tunnel is running 400–500°C. Each unit is built to OEM-fit dimensions—length, diameter, and the R7s connector interface—so it drops straight into Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB machines without any modification. Power and voltage are selected to match your blow molder’s original spec, so the heating curve and cycle timing stay the same.
