On the blow molding floor, the heating tunnel sets the tempo. If preform temperature starts to drift, you’re looking at rejects—thin spots, crystallized necks, and weak biaxial orientation. And that downtime? It stacks up fast. We build infrared lamps specifically for PET and PC preform heating, engineered to hold repeatable thermal profiles on Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB blow molders. What matters under the hood We run short-wave quartz infrared emitters tuned to the absorption curve of PET and PC. The wavelength window keeps the heat on the preform surface and stops energy from bleeding off into the surroundings. Output stays stable across the tube length, so the heating tunnel profile holds from the first row to the last. Specs are straightforward: 120–240 V, standard R7s connectors, and exact arc lengths and diameters to drop into OEM holders and reflectors. Each lamp is rated for 5,000+ hours, and output stays within 5% over that life. Why this matters on your line On your blow molder, repeatable preform heating means fewer rejects and fewer hours chasing setpoints. A stable profile evens out cycle time variability, helps you hold higher throughput, and keeps material orientation consistent. You also see energy come down because the emitter couples with the preform, not the air. And with a long service life and 1:1 dimensional compatibility, replacement frequency drops—so your spare-part inventory does too. Here are the practical details Infrared heating is line-of-sight. Keep reflectors clean and aligned; even a small shift can change the belt profile. Before ordering, verify your blow molder’s lamp length, base, and wattage density—tight tolerances matter. If the reflector geometry isn’t matched, expect slightly higher peak temperatures near the lamp ends. And run with the correct preform color and wall thickness: darker preforms absorb more, so you may need to lower the setting.
