Stop the Headache of Tube Breakage in Your SIG Blomax Lines

Let’s be honest: there is nothing more frustrating than a line shutdown because a heating tube decided to burn out right in the middle of a run. Usually, when these tubes pop, it’s because of structural stress or some annoying voltage spikes. That’s why we built our PC preform softening lamps differently. We didn’t just follow the standard factory manual—we beefed them up. We focused on structural reinforcement so you can actually stop worrying about these interruptions. The Heat Struggle Working with Polycarbonate (PC) is tricky. You need the infrared heat to soak deep into the material to get it soft, but if you overdo it, you scorch the plastic. Our lamps are designed for high-wattage output to keep that heat density consistent across the preform. But here is the thing: your power supply has to be steady. When you’re pushing high wattage through a 400V system, things get incredibly hot. If your oven’s cooling fans are clogged with dust or acting up, the ends of the lamps will overheat. Keep those fans clean. It’s a simple fix that saves a lot of money. Built to Take a Beating Most lamps fail at the pinch seal. It’s the weak point. To fix that, we used reinforced quartz glass and tougher electrodes. High-speed production lines are brutal—especially with those rapid start-stop cycles. These lamps are built to handle that expansion and contraction without cracking. Plus, we use high-purity quartz. This keeps the shortwave IR emission steady. No more “cold spots.” When you have cold spots, the preform stretches unevenly, and that’s exactly how you end up with bottles that burst. Getting Them Running The best part? You don’t need to rewire your whole setup. These are direct replacements for SIG footprints. Just plug them into your existing connectors and you’re good to go. Now, a quick tip on maintenance. Even the toughest lamp can’t fight physics. Check your reflectors. If they’re pitted or oxidized, the heat doesn’t go into the preform—it bounces right back into the tube. That puts massive stress on the quartz and burns the lamp out way too early. Keep those reflectors polished. Your lamps will last longer, and your life will be a lot easier.

Sidel preform heating box parts

On a blow molding line, the heating box is where the run lives or dies. If preform temperature starts to drift, you’ll see the fallout fast—PET bottles splitting at the shoulder, haze showing up in the sidewall, or weight drift that keeps you chasing the fill line. On Sidel machines, the heating tunnel has to be kept tight, and the emitter stack is the first line of control.

Preform reheat lamp 1000W 230V

Out on the blow molding floor, a tired reheat lamp doesn’t just cost you speed. It shows up as uneven preform temperature, thick-walled spots, and too many rejects. When the heating tunnel can’t hold setpoint, the blow molder tries to chase stability by slowing the wheel or cranking power. Either way, you lose output. We built the 1000W 230V preform reheat lamp to deliver OEM-grade performance without the OEM price tag, so you can get back to stable cycles. What matters on the machine is matching energy and interface. This 1000W infrared emitter runs on 230V and draws the same load as standard OEM lamps, so your power circuits and controls don’t need changes. The quartz envelope gives you fast-response short-wave infrared, heating preforms quickly without surface overshoot. It uses an R7s connector and standard lamp lengths, so it drops straight into existing heating zones on Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB machines. And here’s why it works: consistent heat equals consistent stretch. With stable output, you can keep preforms in the intended temperature window, which cuts down crystallinity issues and keeps bottle weight in spec. That translates to fewer jams, less scrap, and more repeatable changeovers. The 1000W rating also covers the heat demand of thicker preforms and faster wheel speeds, so the lamp isn’t the bottleneck when you push the line closer to rated capacity. Before you install, verify the lamp holder and terminal block condition. Corroded contacts cause voltage drop and drive uneven heating. This emitter is a direct-fit replacement, but if your machine uses a different wattage or voltage, confirm compatibility with the heating controller and transformer. Keep the reflector clean and make sure airflow in the tunnel is proper. Infrared lamps run hot, and overheating shortens service life.
