Shock resistant IR radiator for PET machine

On the blow molding floor, downtime isn’t something you watch happen. When an infrared radiator dies inside the heating tunnel, preforms cool unevenly, bottles go off spec, and the line stops. We built a shock-resistant IR radiator for PET machines to keep your Sidel, Krones, SIPA, Husky, SACMI, or Nissei ASB running, even through the roughest cycles. What matters under the hood The emitter uses a quartz envelope with a high-purity halogen filament, tuned for short-wave infrared. That gives you fast thermal response and tight control over preform surface temperature—exactly what stretch blow molding demands. The shock resistance isn’t a pitch; it’s mechanical. Internal supports and a rugged mounting base cut filament stress from vibration and repeated thermal shock. Specs are straightforward: standard 120V/240V options, power matched to OEM heating zones, and R7s connectors for drop-in fitment. We hold dimensional tolerances to match the original lamp geometry, so alignment inside the reflector stays consistent. Why it plays in PET On a PET blow molder, heating is the gatekeeper for output and quality. This radiator hits target temperatures quickly, shortens warm-up, and stabilizes the tunnel profile. The payoff is fewer rejects from inconsistent heating and more uptime between lamp changes. Energy draw stays in line with OEM ratings, so you’re not paying extra for stability. A few shop-floor notes Installation is simple, but the environment is brutal. Confirm voltage and connector match your machine, then check the reflector for oxidation and the holder for spring fatigue. Handle the quartz with clean gloves—oil residues can create hot spots. If your heating zone runs extreme temperatures or sees high air velocity, tell us so we can adjust the base material and mounting hardware accordingly.
