It’s frustrating. You see <a href="https://o-yate.net">those</a> cold spots in the preform, the bottle bursts, and suddenly you&rsquo;re staring at a pile of scrap and a lot of wasted time. The problem is usually simple: the heat isn&rsquo;t hitting the core.</p> <h2 id="how-we-actually-fix-the-heat">How we <a href="https://o-yate.com">actually</a> fix the heat</h2> <p>We didn&rsquo;t want to just make &ldquo;another lamp.&rdquo; We looked at the quartz tube and the spectral output. By tweaking the halogen gas pressure and the filament density, we shifted the infrared wavelength. Why does that matter? Because it&rsquo;s a wavelength the PET polymer actually <em>likes</em> to absorb. Instead of scorching the outside of the plastic while the inside stays cold, the heat sinks in deep. You hit that glass transition <a href="https://henruite.com">temperature</a> faster, and the plastic <a href="https://goldisgood.com">behaves</a> the way it&rsquo;s supposed to.</p>
