If the preforms come out too cool, you get thin <a href="https://o-yate.net">walls</a> and blowouts. Run them too hot and they sag, stretch unevenly, and still blow out. When the IR emitter underperforms, you don&rsquo;t just lose a few bottles—you lose rate, scrap resin, and the confidence that the machine will hold. We built our IR radiator for one job: heating 5-gallon PET preforms on stretch blow molders. Not a generic heater. A direct-fit replacement, laid out around the geometry and power density needed to hit the preform&rsquo;s temperature window quickly—and keep it there.</p>
