On a PET line, the heating tunnel is where you make or break uptime. One lamp starts drifting on output, and suddenly you’re chasing thin walls, haze, and inconsistent stretch. You need a spare that matches the OEM’s electrical and thermal profile—exactly. What matters, technically This infrared lamp is rated 440V, 2500W, built for the high-current demands of blow molding heaters. The quartz envelope and halogen/IR filament put out short-wave energy that gets into PET fast, so preforms hit temperature in a shorter dwell. That tightens the thermal window across the heating zone and helps keep cycle-to-cycle repeatability steady. We match the power and voltage to the blow molder’s heater circuit so you don’t under-heat the preforms or overload the busbar and control gear. Why it holds up in stretch blow molding In stretch blow molding, the preform has to be heated uniformly before it hits the mold. With this lamp, the tunnel holds target temperature with less swing, which cuts scrap from brittle necks and weak shoulders. In practice, that means fewer line stops chasing temperature drift and more consistent bottle weight. Energy use is also more predictable: at 2500W, the emitter heats fast and recovers quickly after door cycles, so you spend less time waiting and more time blowing. Here are the practical details Check the lamp length and base type—usually R7s—against your holder and reflector. The 440V rating is for specific machine configurations; if your line runs a different voltage, pick the correct variant or you’ll get premature failure. The quartz envelope is sensitive to contamination. Keep the reflector clean and don’t touch the tube; oils create hot spots and shorten life. Install with the specified torque and alignment so contact stays solid and heating stays even.

Out on the blow molding floor, a weak infrared lamp doesn’t just cost you time. It throws your heating curve off, and then the bottles start showing stress lines, uneven wall thickness—or worse, pinholes. On Nissei ASB 70DP/150DP lines, staying in control comes down to matching the original heating geometry, watt density, and response time. We supply a Nissei ASB 70DP/150DP infrared lamp that delivers OEM-grade performance, without the OEM price. What matters, technically We build these emitters as direct-fit replacements, engineered to the same core parameters ASB machines expect: quartz tube geometry, filament layout, and stable spectral output so preform heating stays consistent. Wattage, voltage, and connector interface are calibrated to the ASB 70DP/150DP heating tunnel, so you get the same thermal response and repeatable heat-up across the bank. The payoff is predictable stretch behavior and fewer tweaks when you change formats. Why this matters in stretch blow molding Heat uniformity is what keeps cycle time up and scrap down. With these lamps, you restore the original heating profile, so the preform hits the right temperature window—without overheating the neck or leaving the body under-softened. That means faster stabilization after lamp changes, fewer rejects from off-spec bottles, and less downtime chasing temperature drift. You get OEM-level control, but the replacement cost is in line with an OEM-backed alternative, not the premium of the branded part. A few shop-floor reminders Installation is straightforward—same mounting, same alignment—but always double-check lamp orientation and reflector condition. Infrared output is sensitive to reflection geometry; a worn or misaligned reflector can skew the heating pattern even with a good lamp. And keep the heating tunnel clean. Build-up on the quartz tube cuts heat transfer and can push your heating curve off target. Match the lamp to the machine, keep the optics right, and the line runs the way it was designed to.
