On the blow molding floor, the heating tunnel is where uptime and bottle quality get decided. When preforms undershoot or overheat, you pay for it in scrap, slower cycles, and a line that spends the shift chasing temperature instead of running it. The 2500W 400V infrared heating bulb is built to put your blow molder back where it should be—whether you’re running Sidel, Krones, SIPA, Husky, SACMI, or Nissei ASB. What actually matters, technically This short-wave infrared emitter is rated at 2500W on 400V, so it matches the OEM power budget and the way the heating zones are laid out. The quartz envelope responds fast, and the tight thermal profile helps you control the temperature curve along the preform—neck and body. In practice, that means quicker stabilization, repeatable heat penetration, and a heating window that stays consistent shift after shift. Why this matters in blow molding Stretch blow molding only works when the preform is heated properly before it hits the stretch and blow. With this bulb, heat distribution across the tunnel behaves predictably, so you can run the intended cycle without fighting hot spots or weak zones. That shows up as fewer rejects from uneven wall thickness, better clarity, and fewer jams from underheated material. Energy use tightens up too, because the power is matched to the process instead of bleeding off as drift. Here’s what to watch on install Installation is straightforward, but the lamp has to be mounted in the correct orientation and at the specified spacing to keep the heat field where it’s supposed to be. Check the reflector condition and make sure cooling airflow is right—overheating the quartz shortens service life. Also confirm the connector type and voltage match the machine socket; mismatched voltage or sloppy contact gives unstable output and kills bulbs early.
