Fixing those annoying heat spots in your KHS and SACMI lines

Ever deal with bottles that just won’t come out right? Maybe the walls are too thin in one spot, or the whole bottle looks a bit warped. It’s frustrating. Most of the time, the culprit is a messy thermal field in your PET blower. Usually, it comes down to your quartz lamps either wearing out or just not putting out the right kind of heat. The nitty-gritty of heat distribution Here is the thing: the placement of that tiny tungsten filament matters. A lot. If it’s off by even a fraction, you get “cold spots.” And cold spots mean ruined production runs. We make our replacement lamps to fit the OEM footprint exactly. We use high-purity fused quartz because it lets the infrared radiation hit the preform evenly from one end of the tube to the other. It just works. Getting them installed These are simple drop-in replacements. Whether you’re on 230V or 400V, we’ve calibrated the wattage to match your specific resin grade. Plus, we use standard R7s or SK15 connectors. That means you can just plug them in and get back to work without messing around with your sockets. One quick tip: high-wattage tubes put out a ton of heat. Make sure your oven fans are actually doing their job. If the oven gets too hot, you’ll burn through your lamps faster or, worse, warp your preforms. What happens in the real world You don’t have to overpay for OEM just to get a steady heat profile. We’ve tightened the tolerances on the tube diameter and tweaked the halogen cycle to make these last longer. The result? Your first bottle looks exactly like your ten-thousandth. You can finally stop obsessing over your PID tuning and actually trust your oven controllers to do their job.

On a PET line, the heating tunnel is where you earn your uptime and defend your bottle quality. Let one IR lamp underperform and you’ll see the fallout immediately: uneven preform heating, pressure swings in the blow molder, then scrap—weak bottles or blown cavities. The SIPA SFL 6/6 linear blower IR lamp is engineered to keep that tunnel stable, day in and day out, on SIPA SFL 6/6 blow molding machines. What matters under the hood We spec the SIPA SFL 6/6 IR lamp as a short-wave halogen emitter, matched to the machine’s heating-zone geometry. The quartz tube gives you fast thermal response, so the heating profile tracks setpoints quickly when you switch preform colors, weights, or material batches. Output is sized to lay down consistent radiant energy across the full tunnel width, and the lamp uses the standard R7s connector with dimensions that line up with the original SIPA holder. That 1:1 fit is the difference. A mismatched lamp can shift focus, create hot and cold bands, and leave you chasing temperature balance instead of running the line. Why it plays in a linear blower In a linear blower layout, the preform only gets a short window under heat. With the right lamp, it hits target temperature within that dwell, so stretch blow molding runs with repeatable wall distribution and consistent bottle weight. You end up with fewer rejects, more stable cycle rates, and less operator tinkering. Energy stays tight, too—the emitter heats on demand and cools quickly when the machine stops, so you don’t bleed kWh per thousand bottles on long soak losses. Field notes that save headaches Installation is straightforward, but the heating tunnel has to be clean and aligned. A reflector that’s even slightly off will change the spot size on the preform and shift the heating curve. Verify voltage at the terminal, confirm the lamp is seated properly, and set replacement intervals by run hours—don’t wait for a failure. Pushing lamps beyond rated life raises the risk of output drift, and that drift shows up as quality variance long before the lamp looks “done.”
