Getting Your IR Lamps Right for Sidel SBO and Matrix Machines

If you’ve ever dealt with PET blow molding, you know that preheating is where the magic—or the nightmare—happens. You need that heat to be perfectly uniform. When you’re switching from the old-school SBO machines over to the newer Matrix series, the biggest headache is usually trying to keep the heat distribution consistent without having to rip apart your oven chassis. The trick is all in the footprint. We build our lamps to be a mirror image of the OEM Sidel specs. Why? Because if a lamp is off by even 5mm, or if the wattage is slightly wonky, you’re going to end up with cold spots in your preforms. It’s frustrating. We use short-wave IR emitters so the heat hits the PET wall fast. This keeps your cycle times low. Just a heads-up: if you decide to go with a higher wattage than what the machine was originally built for, keep a close eye on your cabling. You don’t want to fry your wiring looms. No rewiring. No drama. Nobody wants to spend their shift rewiring an oven. That’s why we stick to standard R7s and SK15 connectors. You just swap them out and get back to work. We also use doped quartz glass. It basically filters the energy so the heat goes into the plastic, not into the oven walls. It stops your reflectors from baking and wearing out prematurely. The real-world stuff These are true drop-in replacements. You pull the old tube, slide the new one in, lock the connectors, and you’re done. No drilling. No bending brackets. No swearing at the hardware. But here is the thing… a brand-new lamp can only do so much. If your reflectors are pitted or covered in oxidation, you’re never going to hit your target temperature. It’s like putting racing tires on a car with a broken engine. Do yourself a favor: give those reflectors a good clean before you swap the lamps. That’s the only way to actually get the full wattage you’re paying for.

7 Zone blow molding heater tube

On the floor, every minute of unplanned downtime is money out the door. When a heater tube goes down on a 7-zone blow molder, you’re left with scrap preforms, uneven heating, and a mad dash to find a replacement that actually fits. We built our 7-zone blow molding heater tube to cut that scramble out of the equation and get you back to stable, predictable production. What it is, under the hood This is a direct-fit infrared emitter, built for 7-zone heating tunnels on PET stretch blow molding lines. The heart is a high-purity quartz tube with a halogen filament, tuned for short-wave output that gets into PET fast and even. You get standard 240V and 380V ratings, with wattage matched to OEM zone requirements so each zone recovers heat quickly after door cycles. The ends use R7s connectors, and the overall length and mounting geometry are OEM-matched, so it drops straight into the existing brackets without any fuss. Why it matters on a 7-zone line With seven zones, stability is what keeps thin spots, crystallization, and blow-out defects from creeping in. This tube comes up to temperature in seconds, holds setpoint tight, and repeats that performance shift after shift. The payoff is fewer temperature-related rejects, more consistent bottle weight, and a quicker return to full line speed after heat-up or changeover. Energy stays in line, too, because the emitter delivers heat on demand and cools fast, avoiding the steady bleed you get from under-tuned alternatives. A few shop-floor notes Installation is straightforward, but before you swap, double-check voltage and connector orientation against your machine’s terminal layout. Always handle the quartz with clean gloves — oils and scratches shorten life and set you up for hot spots. You’ll get the best performance when the heating tunnel reflectors are clean and aligned. If you run 24/7, put tube inspections on the planned maintenance schedule. Even the best emitter ages, and catching output drift early keeps the process under control.

Electric Blow Heater: 400V Halogen Tubes, Built for PET Preforms

We built this electric blow heater for one simple reason: to get your PET preforms hot—fast. Because when the clock is ticking, you need heat that keeps up with the pace. Our standard unit runs on 400V, delivers 2500W, and uses a 300mm halogen tube. That combination gives you a tight burst of power, softening the neck and body of the preform without turning the whole machine into a sauna.
