Standard heating leaves the neck cold and the body under-softened, so you back off the wheel speed to keep bursts from wrecking your run. The price? Scrap, stretch that’s all over the place, and a lot of extra energy. And the kicker is the time you burn on every changeover.</p> <h2 id="what-matters-technically">What matters, technically</h2> <p>We <a href="https://o-yate.com">built</a> this softening IR lamp for thick-wall preforms. It throws high-intensity short-wave energy that penetrates <a href="https://henruite.com">faster</a> and heats more evenly. The emitter uses a high-purity quartz tube with a tuned filament, optimized for the PET absorption band. That gives you rapid surface-to-core softening without scorching. Power density is matched to the heating tunnel geometry on Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB machines. It drops in with standard R7s connectors and exact OEM mounting dimensions. Output holds steady over 5,000+ hours, with less than 5% drop in irradiance.</p>
