Stop Fighting Your SIG Blomax 4 Heating Issues
Ever feel like you’re chasing your tail with your PET blowing? One minute the bottles look great, and the next you’ve got wall thickness all over the place or weird deformations. It’s frustrating. If you’re running a SIG Blomax 4 or a SIPA rotary, there’s a good chance the culprit isn’t your machine—it’s your lamps. A lot of people try to save a few bucks with generic replacement tubes, but those things rarely hit the original power curves. The problem is the “cold spot.” If a lamp is even slightly off on wattage or voltage, you get uneven heat. It sounds like a small detail, but it’s the difference between a perfect bottle and a pile of scrap. We build our lamps to match the original specs exactly. No guessing. No “close enough.” Just consistent IR radiation so your preforms hit that glass transition temperature exactly when and where they should. Built for the chaos of the shop floor Rotary machines vibrate. A lot. That’s why we use high-purity quartz glass that can handle the shock of rapid heating and cooling without cracking. We also stick to standard R7s or SK15 connectors, depending on your setup. They fit tight. That matters because a loose connection leads to arcing, and arcing is the fastest way to burn out a brand-new lamp. Getting them in is the easy part You don’t need a PhD or a manual the size of a phone book to swap these out. Just pull the old tube, wire it in using the footprint you already have, and you’re done. Since these are built specifically for the Blomax 4, you can forget about messing with your PID controllers or wasting hours tweaking the oven timing. It just works. One quick tip: before you pop the new ones in,check your cooling blowers. Shortwave lamps put out an incredible amount of heat. If your blowers are clogged with dust or just dying, your reflectors will overheat. That’ll kill your new lamps way faster than they should go. Give the airflow a quick look first, and you’ll get a lot more life out of your gear.
