On a line pushing 14,000 to 18,000 bottles per hour, the heating tunnel is where you win the schedule or lose it. Let the heat profile drift, and you’re staring down brittle necks, haze on the sidewall, and a sudden jump in scrap. We built the 480V 3000W infrared lamp for blowing to keep that tunnel steady, even when ambient temperature swings and the conveyor never stops. What matters, technically This emitter is built for blow molding duty. 480V input and 3000W output give you predictable power density, so the preform surface hits set temperature fast—without overshooting the crystalline limit. The quartz envelope and halogen filament deliver short-wave infrared that penetrates the PET wall evenly, so the temperature rise across the preform is repeatable. We match the lamp to the OEM heating zone geometry, so thermal distribution stays uniform from the neck ring down to the bottom. Power matching is 1:1 to the blow molder’s heater bus, with standard R7s connections and the right mounting footprint for a quick swap-in. Why it works in the real world In stretch blow molding, cycle time comes down to how quickly the preform reaches the right stretch temperature. With this lamp, you shorten warm-up, stabilize the dwell, and cut variation in bottle wall thickness. The payoff: fewer pinholes, stronger top-load performance, and a lower reject rate on heavy-weight and specialty containers. Energy use drops because the lamp heats on demand and holds setpoint without big cycling. On Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB machines, it runs like OEM—just faster to stabilize and easier to keep running. Here’s what to watch for Installation is straightforward, but alignment is everything. The lamp has to sit on the reflector’s focal line; even a small offset throws off the heat map and drives uneven heating. Keep the reflector clean, and check lamp seating every time you replace it. Expect high surface temperatures—use proper shielding and verify voltage at the terminal. For best life, match wattage to the zone design. If you run undersized lamps in an oversized zone, you’re back in the scrap cycle.
