Getting Your SIG Blomax 4 Heat Just Right

If you’ve spent any time with a KHS or SIG Blomax 4, you know the headache of uneven heat. One part of the preform stretches perfectly, while another stays too thick. It’s frustrating. You end up fighting the machine just to get a consistent bottle. We got tired of seeing those hot and cold spots, so we built our replacement infrared lamps to actually fix it. We focused on the boring stuff—like tighter filament winding and cleaner quartz—because that’s where the real difference happens. The Power Side of Things The Blomax 4 is picky. It needs a very specific balance of wattage and voltage to keep that PET preform in the sweet spot. Our lamps are built to fit the original footprint exactly. You just pop them in. No fuss. We use high-wattage shortwave lamps because they hit hard and fast, which is what you need when you’re running high-speed cycles. But a quick heads-up: pushing these to the limit puts more stress on your oven’s ventilation. If your cooling fans are caked in dust, these lamps will burn out way faster than they should. Keep those fans clean. Better Glass, Better Heat Here’s the secret: we use high-purity quartz. Most glass absorbs some of the heat itself, which just wastes energy and heats up your housing. Our quartz lets the energy fly straight into the preform. We also fixed the “edge-effect.” You know how the heat usually drops off at the ends of the tube? We centered the filaments better to stop that. Now, the heat is flat and even across the whole zone. What Happens on the Floor Installation is a breeze. We use standard industrial connectors, so you don’t have to touch your wiring or “modify” anything. In the real world, we’ve seen these tubes match or even beat the OEM versions. The best part? You stop spending your shift constantly tweaking the heating zones. You set it, it stays consistent, and you can actually focus on other things.

On a blow molding line, uneven preform heating isn’t just a speed killer. It shows up as wall thickness variation, crystallization, and scrap that piles up fast. When the heating tunnel can’t hold temperature across cavities, you end up chasing setpoints instead of running stable cycles. The Sidel SBO 4 infrared lamp is built to get you back to the OEM heating profile—without guesswork. What matters, technically We built the SBO 4 as a direct-fit infrared emitter for Sidel SBO blow molders, with 1:1 parameter matching to the machine’s heating tunnel interface. The lamp uses short-wave infrared in a quartz envelope, so it responds quickly and holds tight control during preform heating. It’s rated for standard line voltages and uses the same connector and mounting as the original, so you can swap it in without modifying brackets or rewiring the heater block. In practice, that means faster warm-up, repeatable temperature across cavities, and less drift during long runs. Here’s why it works in stretch blow molding: the heating phase sets everything that follows—cycle speed, bottle weight, and the reasons you get rejects. The SBO 4 restores the energy density and dwell timing the machine was designed for, so the heating curve stays consistent even when you push higher line speeds. Operators see fewer alarms tied to temperature deviation, and maintenance gets predictable lamp life, which cuts unplanned changeovers. The payoff is stable output, less scrap, and less downtime spent tuning the tunnel. Installation is straightforward, but keep the heating window clean. Dust on reflectors and quartz surfaces robs output and can create hot/cold spots. Match the lamp to the exact wattage and length specified for your SBO model; mismatched emitters can cause over- or under-heating that shows up as quality issues even when the machine looks fine on the surface. Plan replacement around preventive maintenance, not failure, and you keep the line running at the rate it was built to deliver.
