If the temperature profile isn’t right across the body and neck, the stretch goes sideways—wall thickness drifts, hazing shows up, stress marks follow. You can run the heater and see the power readings look good, but repeatability can still slip away. The problem usually isn’t intent. It’s control, stability, and how the heat actually couples into the PET. We built infrared preheating for one reason: get a repeatable temperature profile into the preform quickly, and hold it steady cycle after cycle. This isn’t window dressing. It’s the first step of stretch blow molding, and it sets the ceiling on your uptime and yield.</p>
