Stop the Constant Lamp Swaps on Your SIG Blomax Lines

If you’re replacing tubes every few weeks, you already know how frustrating it is. It’s not just the cost of the parts—it’s the downtime, the annoyance, and the feeling that you’re just fighting a losing battle. Most people think it’s just a bad batch of filaments. But usually, it’s something deeper. Between the mechanical stress and the thermal shock, those lamps are just taking a beating. We decided to fix that. We make IR lamps specifically for these lines that actually hold up under the pressure of a high-cycle operation. The heat struggle To get PET blowing right, you need a massive hit of heat, and you need it instantly. That’s the only way the plastic stretches the way it should. But here’s the catch: pushing that much wattage through a tiny quartz tube creates a ton of internal pressure. If the seal is off by even a fraction, the tube snaps. Simple as that. To stop the bleeding, we used a thicker quartz wall. It handles the pressure without changing the size of the lamp, so it still drops right into your existing setup. It’s all in the fit A lot of lamps fail at the pinch seal or where they plug in. Think about the vibration on a machine running 24/7. If the lamp is even slightly loose in the socket, you get electrical arcing. That creates a “hot spot” at the base that burns the lamp out way before its time. We tightened the tolerances on our connectors and beefed up the end-caps. No shifting, no arcing, no premature burn-outs. A quick reality check Look, these lamps are built to take a beating, but they aren’t magic. They put out an incredible amount of ambient heat. If your cooling fans are choked with dust or your airflow is blocked, the lamps will overheat regardless of how thick the quartz is. Keep your cooling systems clean. Do that, and you’ll actually get the full lifespan out of the quartz.

Getting Your Sidel Heating Lamps Right (Without the Headache)

If you’ve spent any time around PET stretch blow molding, you know the struggle. One wrong move with your thermal profile and suddenly you’re staring at pearlescence or thin walls that just won’t hold. It’s frustrating. That’s why we make infrared heating bulbs that actually fit. Whether you’re still running the old-school SBO lines or you’ve moved up to the Matrix series, these are designed to slide right in. The nitty-gritty on power We’ve matched our lamps to the exact voltage and wattage your Sidel oven expects. Whether you’re on 230V or 400V, the goal is simple: get that preform to the glass transition temperature without scorching the neck. To make that happen, we use high-purity quartz glass. It can take the hit of rapid heating and cooling cycles without cracking. But here is a pro tip: keep an eye on your power supply rails before you swap them out. If you decide to push the wattage higher than what the OEM originally called for, your cabinets might start running hot. And when cabinets get too hot, contactors fail. Nobody wants that mid-shift. No rewiring, no fuss We use standard R7s and SK15 connectors. Why? Because you shouldn’t have to rewire your entire machine just to change a bulb. They are true drop-in replacements. We also add a special coating to the quartz. Instead of wasting heat on the machine frame, this coating shifts the infrared spectrum so the heat goes exactly where it belongs—into the PET. We’re also obsessive about the dimensions. If a bulb is off by a fraction, it rattles in the reflector. And if it rattles, it burns out early. We keep the tolerances tight so they stay put. A few things to watch out for These work great for Matrix and SBO series, but there’s a trade-off. That coated quartz is a beast at transferring heat, but it’s a bit more fragile than the uncoated stuff. Please, use gloves. If you touch the glass with your bare hands, skin oils leave marks. Those marks create hot spots, and the lamp will likely snap the very first time it heats up. Just seat them properly in the reflector, keep the oils off the glass, and they’ll last as long as they’re supposed to.
