PET on Quartz IR Heating Elements

Bulk buy IR lamps for PET blowing plant

Introduction

We make bulk infrared (IR) lamps built specifically for Sidel Matrix blow molding lines. The whole point? Drop our lamps in, and the temperature rise follows Sidel’s original spec. It’s a straight swap—engineered so your PET heating stays steady, no guesswork.

Power, Voltage, and Fit: The Practical Details

Here’s the thing about Sidel Matrix heating sections: the thermal space is tight, and every millimeter matters. So we match the original footprint—same lengths, same clearances—so the lamp sits right inside the reflector without casting shadows. We run these at high voltage, typically 400V. Why? Because it delivers the same power with lower current. And lower current means smaller wiring, less voltage drop at the terminals, and a cooler electrical cabinet. Wattage is tuned for the heat density the PET parison actually needs. Too low, and the cycle drags. Too high, and you risk scorching. Our lamps hit setpoint fast—then hold it steady, without the temperature wobbling.

Customized IR module for PET factory

On a PET line, the heating tunnel is where you earn your stability. Preforms arrive with tight tolerances, and the blow molder needs wall temperature that’s consistent before stretch. If the IR output drifts or lamp-to-preform distance is even slightly off, you’ll see uneven stretch, weak necks, or crystallization. Then the downtime starts. We built a custom IR module to drop in as a direct replacement for the OEM heating—1:1 geometry and electrical fit—so you can swap it in without re-engineering the tunnel. What actually matters is matching the energy profile to the preform. Our module runs short-wave infrared with quartz emitters, tuned to PET absorption peaks so heat penetrates fast without scorching the surface. Power is sized to your blow molder’s cycle—Sidel, Krones, SIPA, Husky, SACMI, or Nissei ASB—and we match the original voltage, connector type (typically R7s), and mounting. The payoff is repeatable heating with tighter band control, so stretch ratios stay stable and rejects drop. Here’s why it works: it puts the machine back inside its designed heating window. You keep the same preform path, the same dwell, and the same timing, but you remove variability from lamp aging and drift. You get faster warm-ups, fewer lamp changes, and lower kWh per thousand bottles. In practice, that means more uptime and less scrap. One thing to get right: customization needs the right interface data. Send us the OEM lamp specs, the heating zone layout, and the preform geometry. The module will fit, but you still have to verify clearances and reflector alignment in your tunnel—misalignment moves the hot spot and wipes out the gains.

Out on the plant floor, one mismatched heater element in the preform heating tunnel is enough to stall the whole line. You get uneven stretch, bottles that blow out, and that mad scramble for a replacement that actually fits. We make OEM-grade PET blow molding heater elements that match the original specs for Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB machines. What we build, technically These are short-wave infrared lamps—quartz tubes with halogen filaments, sized for standard blow molder tunnels. Typical ratings run 1000–3000 W, 230/460 V, with lengths from 300 mm to 1200 mm. You get R7s connectors, and we can do custom terminals when the machine calls for it. Fast response and a focused spectrum get preforms up to temperature quickly, and stable resistance keeps power consistent across the heating profile. Why it plays in production Tight dimensional tolerances and repeatable watt density give you uniform preform temperature, so stretch blow molding runs the cycle it was designed for. You use less energy because the emitter turns more of the input into usable heat, and longer lamp life means fewer changeovers. On Sidel, Krones, and the rest, that means fewer rejects, steady output, and maintenance windows you can actually plan around. Here is the part that matters on the line Infrared heating is finicky—reflector cleanliness and preform spacing make a real difference. Set the lamp at the correct gap to the preform path, keep reflectors free of oxidation, and double-check voltage and connector match before you swap it in. In humid or high-dust environments, protect the lamp ends and verify the cooling airflow; that’s what keeps output stable and the lamp life honest.
