Oil bottle runs are brutal on the heating tunnel. Thick-wall preforms need deep, even heat. Undershoot, and you get stress lines. Overshoot, and you scorch the neck ring. Either way, you lose yield and pace. We built this thick preform heater for exactly that reality—OEM-grade, engineered for repeatable temperature control on Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB blow molders. What actually matters under the hood It runs on short-wave infrared halogen emitters with quartz tubes—fast response, tight spectral output for PET. You can spec 2400–3600 W, 220/240 V or 380/400 V, and standard R7s connectors so it drops in clean. The reflector geometry focuses energy on the preform body while keeping the neck ring shielded. The heater block is held to OEM tolerances, so you swap it in without reworking the tunnel. Materials and welds are spec’d for 24/7 duty, and every lamp is aged and measured before it ships, against a documented QC curve. Why it holds up on oil-bottle profiles Oil bottles demand more heat than water or carbonated lines because the walls are thicker and the stretch profile is longer. This heater holds that profile with stable output, so you see fewer rejects from uneven wall thickness and faster cycle recovery after tool changes. You also trim energy use because the emitter hits setpoint quickly without overshoot, and downtime drops because the lamps last longer and alignment stays repeatable. The details that save you headaches Installation is straightforward, but match the voltage and connector type to your blow molder’s socket, and confirm tunnel clearance—reflector depth can vary by model. Set the heater to the preform’s optimal absorption band and keep the emitter surface clean; otherwise output drifts. We provide the full OEM replacement specs and tolerance sheets, so you can verify fit before you change over.
