On the floor, the oven heater is the heartbeat of your PET stretch blow molding line. When preform heating starts to drift, you know it immediately—scrap bottles piling up, top load all over the place, and the line losing pace. We build infrared oven heaters to stop that drift and give you control back. Here’s the technical part: you have to match the physics to the process. Our emitters run short-wave infrared with fast response, so the heating curve can track preform wall thickness and material grade. We spec quartz tubes and halogen lamps in the standard power bands to line up with OEM profiles, and we use R7s connectors so swap-in is quick. Output stays stable across the heating tunnel, and the reflector geometry keeps the energy where it needs to be—on the preform shoulder and body—without hot spots. Why it works in the real world is straightforward: it fits, and it performs. Our oven heaters drop into Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB blow molders with 1:1 parameter matching, so you don’t have to re-tune the whole oven. The payoff is fewer rejects, consistent bottle weight, and cycle times you can count on. Energy use comes down because the heaters hit setpoint fast and hold it with tight control. Replacement intervals stretch, which eases downtime and spare parts pressure. A couple of practical notes. Confirm voltage and connector type before ordering, and keep the reflector path clean. Dust and flaking build up fast in the heating tunnel and will skew output. If your line runs heavy color or thick-wall preforms, let us know. We adjust the emitter spectrum and power density to keep the preform in the sweet spot for stretch blow molding.
