Introduction
We built the Sidel SBO 16 Series 2 heater lamp bulb to be a straight-up, no-fuss replacement for the original. It’s a shortwave infrared halogen lamp, designed to deliver steady, focused heat for PET blow molding. The whole point? Get the bottle neck and parison to the perfect temperature, fast. No need to tear your machine apart to make it happen.
The Real-World Specs
Let’s get into the details, but keep it real. This lamp is built for the daily grind of industrial blow molding. It runs on 400V and pulls 2500W across a 300mm quartz tube. That power is intentional. It packs the heat into a tight spot, so you can warm up the parison in a flash without turning the whole machine into a sauna. And that 300mm length? It’s a perfect match for the standard heating zone on SBO 16 lines, so the heat hits exactly where it needs to.
What It’s Made Of
At the heart of this lamp is a shortwave infrared halogen element, snug inside a high-purity quartz tube. The halogen keeps the filament steady, even when things get scorching hot. That means you get consistent performance, shift after shift. The quartz tube is tough, too. It handles sudden temperature swings without cracking and stays clear—no clouding to worry about. And we went with an R7s connector because it gives you a solid, two-point connection. It can handle the current without sparking or arcing. This whole thing is built to survive the constant vibration and heating and cooling inside a blow molder.
How It Feels on the Line
When you’re running PET blow molding, your whole rhythm depends on heating that’s consistent. This lamp responds quickly and gives you predictable control, so you can keep your cycle times steady without any hot spots. It’s designed as a drop-in replacement for most global blow molding machines, which means less time spent on engineering and changeovers. Just keep in mind, a 400V, 2500W lamp throws off serious heat. Your machine’s cooling and airflow need to be up to the task to keep everything running safely. But when it’s all set up right, you’ve got a tough, standardized heating solution that just keeps your line moving.
