A Better Way to Handle Your Sacmi SBF 12 Lamps
Let’s be honest: replacing heating lamps in a PET blow molding line is usually a headache. Most of the time, you’re stuck with proprietary specs that basically force you to buy from the OEM, whether you want to or not. We got tired of that cycle. So, we built a shortwave infrared halogen lamp specifically for the Sacmi SBF 12 that actually fits without the drama. It’s a true drop-in replacement. Getting the heat right Here’s the thing about the SBF 12: you need a very specific kind of heat. Too little and the preform doesn’t soften; too much and you get that annoying pearlization or a melted neck. We focused on high-wattage density to match what the original equipment puts out. By tweaking the tungsten filament, we make sure the heat stays concentrated right in the center of the tube. No more “cold spots” in your preforms. Just a steady, consistent heat from one end of the oven to the other. The nuts and bolts We used high-purity quartz glass because it doesn’t freak out when the temperature swings rapidly. Standard glass just can’t handle that kind of thermal shock. Plus, the halogen cycle keeps the tungsten from gunking up the inside of the glass, so your lamps don’t dim as they age. As for the connection, we use standard R7s or SK15 connectors. Depending on which version of the machine you’re running, it just plugs right in. No rewiring, no modifying holders, no swearing at the sockets. Real-world talk Because we stuck to the physical footprints the industry already uses, these work in about 95% of global blowing equipment. You can swap them into your Sacmi line and be back in production in a few minutes. But a quick heads-up: if you push these lamps to their absolute max wattage, your oven’s cooling fans are going to work harder. If your vents are clogged or your airflow is weak, you might overheat the lamp holders. Just double-check your airflow before you crank the power up to ten.
