It’s frustrating. Usually, if you&rsquo;re seeing &ldquo;cold spots&rdquo; or that cloudy, pearlescent look on your preforms, it isn&rsquo;t a mystery. It almost always comes down to how the lamp is aligned and what the filament is actually doing.</p> <h2 id="the-truth-about-heat-distribution">The truth <a href="https://o-yate.com">about</a> heat distribution</h2> <p>We build our <a href="https://goldisgood.com">Replacement</a> IR lamps to fit the KHS oven footprint exactly. But the real secret is in the winding. If the filament is bunched up too tight at the ends, you get hot spots that scorch the plastic. It&rsquo;s a mess. We use a calibrated winding process to keep the watt-density steady across the whole tube. You get a flat, even heat profile. No surprises.</p>
