A Better Way to Fix Your SIG Blomax 4 Lamps

If you’re running a SIG Blomax 4, you know the drill. Those short-wave infrared (SWIR) lamps are the heart of the machine—they do all the heavy lifting to soften the preforms before they stretch. But when one burns out, it’s a headache. Usually, the first instinct is to call the OEM and wait weeks for a proprietary part. But here’s the thing: you don’t actually have to do that. We build our lamps to mirror the exact electrical and physical footprint of the originals. Because we stick to those specs, our lamps fit just about 95% of the blowing equipment used globally. It’s a straightforward swap. Getting the heat just right Heat is a balancing act. We use high-wattage halogen filaments wrapped in heavy-wall quartz, but the magic is in the precision. If the wattage is too low? You get “cold spots” and uneven heating. Too high? You’re scorching your plastic. We spend our time tweaking the filament length against the voltage so the heat hits the preform exactly where it needs to. No guesswork. No weird wiring required Nobody wants to spend their afternoon modifying sockets. That’s why we use standard R7s or SK15 connectors. You just plug them in and go. We also treat the quartz glass so it can handle the constant “hot-cold-hot” cycling that happens during blow molding. And if you need the heat to penetrate the PET wall faster, we’ve got coated options that shift the emission spectrum to speed things up. Putting them to work These are true drop-in replacements. You pull the dead lamp, slide ours in, lock the clips, and you’re back in business. One quick tip, though: if you decide to push the wattage to the limit to squeeze out faster cycle speeds, keep an eye on your cooling fans. More heat means more load on your oven. If your airflow is clogged with dust, the ambient heat will eat through your lamps faster. Keep those fans clean, and your lamps will last. We keep these in stock and ready to ship. It turns a “weeks of downtime” nightmare into a “few days” fix.
