Out on the line, an ADS blow molder doing PET stretch blow molding lives and dies on repeatable preform heating. Once the infrared lamps start to age, the heating tunnel drifts—hot spots, cold spots, and inconsistent stretch. That means scrap and surprise stops. We built our ADS infrared lamp replacement to bring the heat profile back to the OEM intent. No guesswork. What matters, technically We spec the emitter to match the ADS heating tunnel geometry and power density: short-wave infrared, quartz envelope, rated 2400 W at 230 V, R7s base. The filament layout is set so the focal line stays stable across the preform shoulder and body. Lamp length and end-seal design clear the reflector clamps and ceramic holders without interference. Output stays flat over the service window, tracking within tight tolerance. Set the tunnel zones once and keep the cycle. Why it works on an ADS On an ADS blow molder, the preform has to hit the right temperature before stretch blow molding. These replacement lamps restore the intended heat curve, so you see fewer pinholes, better weight control, and less neck distortion. Energy draw stays close to the original, and lamp changes drop because the materials take thermal shock and repeated start-stop cycles in stride. The payoff is more uptime and fewer quality excursions between scheduled maintenance. Here is what to watch for Installation is straightforward, but you still need to check reflector alignment and ceramic seating. Verify voltage and connector fit against the machine label—mismatched bases or under-rated sockets will cut lamp life. Pair the lamp with a clean reflector. If the reflector is pitted, replace it too. Expect a short warm-up drift after start-up; set zone control with a pyrometer to lock the setpoint.
