Slow or uneven heating? You’ll see it immediately. You’re running heavy preforms, thick walls, and a long stretch path. When the heating tunnel can’t hold a stable, repeatable thermal profile, biaxial orientation goes sideways—weak shoulders, necks off-center, and scrap that climbs. Changeovers drag. Energy use creeps up. The heater that came with the machine was spec&rsquo;d for smaller formats. It was never meant for the thermal mass of a 5-gallon preform. We built the 5-gallon large preform IR heater to swap guesswork for repeatable engineering. It’s a direct-fit infrared solution, designed for large-container stretch blow molding. The goal is controlled heating from the neck to the bottom dome, without hot spots or cold bands.</p>
