When preform temperature starts drifting, you see it immediately—<a href="https://o-yate.net">stretch</a> marks, wall thinning, rejects piling up. Traditional convection is slow, fights ambient drafts, and bleeds energy. Infrared radiation hits the preform directly, heating the PET in seconds, not minutes.</p> <h3 id="what-matters-technically">What matters, technically</h3> <p>We build short-wave infrared emitters around a quartz tube and a halogen lamp filament, giving fast-response heat with tight spectral control. The output is tuned to PET absorption, so the energy goes into the material, not the air around it. Standard specs are 2400 W to 3600 W per emitter, 230 V or 400 V options, and R7s connectors for a drop-in fit. The heating zone footprint stays compact, so you can swap in new elements without reworking the tunnel geometry. Response is near-instant: power on, heat on. Cycle stability improves because temperature recovers quickly between shots.</p>
