That&rsquo;s a rookie mistake. You need that infrared energy to actually sink deep into the plastic wall without torching the outside. If you&rsquo;re running Sidel SBO 20 Series 2 or Husky HyPET high-speed lines, that&rsquo;s exactly why we built our replacement lamps the way we did.</p> <h2 id="the-science-of-the-deep-soak">The science of the &ldquo;deep soak&rdquo;</h2> <p>Here is the thing: to get heat to pierce through the wall quickly, you need short-wave infrared (SWIR). We play around with specific quartz blends and halogen fills to make sure the light spectrum is hitting exactly where it needs to. It&rsquo;s a balancing act. If the power density is too low, you end up with cold spots and bottles with wonky wall thickness. But push it too hard? You&rsquo;ll burn the resin. We spec <a href="https://o-yate.net">these</a> tubes to hit that sweet spot right in the middle.</p>
