Stop the Cycle of Blown Lamps on Your SIG Blomax Line
There’s nothing more frustrating than a SIG Blomax line grinding to a halt because a lamp decided to quit. Again. Usually, when these tubes burn out way too early, it’s not just bad luck. It’s usually a mix of structural stress and thermal shock. The lamps just can’t handle the heat swings. That’s why we build our preform heaters to be reinforced, drop-in replacements. We wanted to make something that actually lasts. The struggle with heat and stress Most standard lamps tend to snap at the pinch seal or right where the electrode hits. It’s a weak point. We fixed that by using a reinforced quartz construction. By tightening up the filament tension and using high-purity quartz, the tube doesn’t freak out when it expands and contracts during the heating cycle. Plus, we’ve matched the footprint of the SIG oven exactly. This means the heat hits the preform right where it needs to, exactly when the mold needs it. No guesswork. Getting the connection right Here’s the thing: the connection point is where a lot of these failures actually start. If the fit isn’t perfect, you get arcing and overheating at the terminals. We use precision-fit connectors to stop that from happening. Whether you’re running high wattage for those fast cycle times or specific voltage ratings, we’ve tuned the internal geometry to kill off those annoying hotspots. The result? You get a steady stream of short-wave IR. Your PET reaches that glass transition temperature perfectly, without scorching the outer wall. A quick heads-up on high output If you’re pushing more wattage through a shorter tube to speed up your line, you’re increasing the heat density. It works great for production speeds, but it does put more pressure on your cooling fans. If you’re running these at max capacity, just double-check that your ventilation is keeping up. You don’t want ambient heat warping your reflectors. The best part? These are direct replacements. You just pull the old tube out, wire the new one in, and get back to work. No need to mess with the machine chassis or spend hours on a retrofit.
