On the floor, a blown bottle reject is more than just scrap. It’s resin you paid for, cycle time you lost, and a line stoppage that’s just waiting to happen. On your SIPA stretch blow molder, the heating stage is where the whole run lives or dies. When the original lamp burns out, you need a replacement that hits the same thermal targets—without forcing you to pick between downtime and a premium invoice. What matters, technically The SIPA infrared lamp 2500W SK15 is a short-wave infrared emitter built around a quartz envelope and a precise filament geometry. It’s engineered for fast response and stable output inside the heating tunnel. At 2500W, it delivers the heat flux needed to bring the preform wall temperature up quickly, so the stretch blow cycle can keep pace without scorching the outer surface. The SK15 footprint and the R7s connector interface match the OEM mounting and wiring, so the lamp drops straight into the existing holders—no bracketing, no re-engineering the heating zone. Why it works on a SIPA line On SIPA blow molding lines, preform heating has to be repeatable, shift after shift. If the lamp underperforms, heating goes uneven—some preforms run hot, some run cool—and you end up chasing quality by slowing the machine down. This lamp brings you back to the original heating profile: consistent temperature across the tunnel, faster recovery after door openings, and fewer rejects from inconsistent stretch. You keep the same cycle rates and the same output, but you do it with a replacement that costs far less than the genuine part. Here’s what to watch for Installation is straightforward, but alignment is everything. Set the lamp position and reflector geometry exactly as the machine specifies; even a small offset moves the hot spot and can shift bottle thickness distribution. Also, double-check your power supply and cooling airflow. The 2500W load needs stable voltage and adequate cooling—restricted airflow will shorten lamp life. Plan replacements during scheduled maintenance and keep spares on hand so you don’t get stuck waiting.
