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.
