If preform temperature starts to drift, stretch <a href="https://henruite.com">becomes</a> inconsistent, you start seeing crystallized spots, and scrap piles up fast. We built the R7s halogen heater lamp for PET preheat to stop that drift where it starts.</p> <h2 id="what-matters-technically">What matters, technically</h2> <p>The lamp uses short-wave infrared, so it responds quickly and gives you tight control right there in the heating tunnel. We match the R7s base and the quartz envelope to the OEM footprint, so it drops straight into Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB blow molders without any rework. Typical ratings cover 100–240V, and power density is matched to preform wall thickness. The energy profile stays repeatable shift after shift. The filament layout and reflector geometry are tuned to spread heat evenly across the preform body and neck, cutting down hot spots and cold zones that cause bursts or weak shoulders.</p>
