Getting Your Heat Right on Sidel Matrix Systems
Here is the problem with swapping out infrared lamps in a Sidel Matrix or Sacmi SBF 24 blower: if the heating curve shifts even a little bit, you’re in trouble. When the wattage or spectral output is off, your preforms don’t heat evenly. That leads to those annoying wall thickness variations or that cloudy, pearlescent look in the final bottle. It’s a headache you just don’t need. That’s why we build our replacement lamps to match the original specs exactly. 1:1. No guessing.
It’s more than just wattage
A lot of people think as long as the wattage matches, they’re good to go. But it’s not that simple. To get the heat right, we obsess over the voltage and the filament diameter. Why? Because we want the heat density per millimeter to be identical to the factory lamp. This ensures the infrared radiation sinks into the PET preform at the exact same rate it did on day one. The best part? You won’t spend your entire afternoon recalibrating oven zones or messing with conveyor speeds. You just pop them in and get back to work.
The nitty-gritty stuff
We use high-purity quartz glass because these things take a beating with constant rapid heating and cooling. We also spent a lot of time on the connectors. They fit tight. No loose ends, no arcing, and no overheating at the terminals. We also tuned the spectral distribution—specifically the shortwave IR—so the heat actually hits the plastic instead of just warming up the oven walls.
Real talk: What happens on the floor
Now, a quick heads-up. High-output IR lamps put a lot of stress on your power supply. Even with the best lamps in the world, a worn-out contactor or some frayed wiring will kill your consistency. If you have a loose connection at the lamp holder, you’ll get a voltage drop, and your heating will go all over the place. And please,keep your reflectors clean. A layer of dust can cut your heat transfer by 20%. That forces your lamps to run hotter just to keep up, which burns them out way faster than they should. A little cleaning goes a long way.
