On the blow molding floor, the day’s uptime is decided in the heating tunnel. If preform temps are uneven, if warm-up is sluggish, or if lamps drift out of focus, you’re chasing instability—thin walls, stress whitening, and unplanned stops. We supply infrared heating lamps built to match OEM performance on Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB machines, so you keep control of the heat instead of reacting to it. What matters under the hood These emitters are short-wave halogen/quartz, tuned for quick response and repeatable output. Power is matched tightly to each heating zone, spectral density is predictable, and filament geometry stays stable so the hot spot stays where it should. We specify the exact voltage, wattage, envelope length, and connector type—usually R7s—so the lamp drops in and aligns with the original mounting and reflector geometry. The payoff is a repeatable temperature profile, consistent thermal uniformity, and a clean, controllable heating curve across the preform wall. Here’s why it plays in stretch blow molding. Preform penetration has to be fast, but controlled. These lamps ramp up quickly so the tunnel hits setpoint fast, then hold it with minimal drift. That means fewer rejects from cold shots or overheated necks, and bottle weight and clarity that stay steady run after run. Energy use drops because the system spends less time chasing temperature and more time in steady state, and lamp life stretches the changeover interval—fewer interruptions, fewer spares tied up on the shelf. The practical details that make it work Power density has to match the blow molder’s reflector and zone layout—no shortcuts. Install with clean contacts, confirm focal alignment, and make sure the heating controller can handle the lamp’s inrush current. Short-wave IR runs hotter visually, so use proper shielding and clear safety labeling. After each lamp swap, run a short warm-up calibration to re-establish the temperature curve and confirm the heat field distribution before you push back to full speed.
