Infrared module for high speed coater

On the line, a high-speed coater on your blow molder can turn a normal shift into a fire drill. Halogen lamps burn out early, preform heating drifts, and every unplanned stop hits you in scrap and labor. You need heat that stays tight, lasts longer, and drops in without a bunch of rework. What matters under the hood We built the infrared module for high-speed coaters around short-wave quartz emitters—fast response, stable output in the heating tunnel. The body is compact, industry-standard, and terminated with an R7s connector so it drops straight into the existing sockets on the coater carrier. Rated 240 V and matched to the OEM power profile, the control system sees a load it recognizes. Peak wavelength is tuned for PET absorption, so you get even preform heating across the neck and body without hot spots. Why it plays in stretch blow molding Coater heating is what governs stretch rate and repeatability. With this module, the temperature band tightens up, so the first bottle and the thousandth run with the same stretch profile. That means fewer pinholes, tighter weight control, and less scrap. Energy use drops because the emitters hit setpoint fast and hold it with minimal oscillation. And with service life that routinely clears 5,000 hours, you cut lamp changes—and the downtime that comes with them. The field notes you’ll appreciate Installation is plug-and-play on the socket side, but you may need to retune the heating window a touch. Match emitter power to the original coater setting, then verify dwell time and preform rotation speed to keep heat distribution uniform. Double-check lamp length and connector orientation against your specific machine model. Dimensions vary between coater carriers, and clearances are tight. Once it’s set, keep the reflector clean and dry—even a thin film buildup can shift output and push preform temperature off target.
