Getting Your SIG Blomax 4 Heating Back on Track

When your infrared lamps start wearing out in a SIG Blomax 4, it’s easy to think of it as just “losing heat.” But it’s actually more about control. If your thermal profile is off, you start seeing those annoying wall thickness variations and your cycle speeds take a hit. Here is the real deal on getting it right. The trick with the heat profile The Blomax 4 uses shortwave infrared to get that PET resin soft and ready without melting the neck. When you pop in new lamps, you’re basically resetting the heat density. If you go with a lamp that has too much wattage per centimeter, you’re going to scorch the plastic. It happens. That’s why we make our replacements match the original footprint exactly. It keeps the gap between the lamp and the preform consistent, so you don’t have to guess. The gear under the hood We use high-purity quartz glass because these things take a beating with the constant rapid cycling. We also add specific coatings to the lamps. This pushes the energy into the PET material where it belongs, instead of just heating up the oven walls. As for the installation? It’s simple. The connectors are standard industrial interfaces. You just drop them in. No need to spend your afternoon rewiring control cabinets. What this actually does for your production New lamps mean shorter warm-up times and a heating zone that actually stays stable. That’s the part you’ll actually feel. You can push the machine faster. Your bottle weights stay consistent. Fewer rejects in the bin. It just runs smoother. But there is one thing to watch out for. More heat means your oven’s exhaust system has to work harder. If you decide to go with higher-output lamps, take a look at your cooling fans. If the oven can’t dump that extra heat, your electronics might get too hot, or the preform necks could soften and deform during the blow stage. Just make sure your lamp wattage plays nice with your cooling capacity.

A Better Way to Handle IR Lamps for Your SIG Blomax 4/6/8

Let’s be honest: when an infrared lamp pops on your SIG Blomax line, everything stops. It’s a headache you don’t need. That’s why we built our replacement lamps to be simple “drop-in” fixes. No jumping through hoops, no brand-specific restrictions. They just work—not just for SIG, but for about 95% of the blow molding gear out there. Getting the heat right The trick is hitting that sweet spot where the PET preform reaches the glass transition temperature without actually scorching the plastic. We matched the electrical footprint of the original SIG specs exactly. Why? Because nobody wants to spend their afternoon rewiring control cabinets. These shortwave emitters give you that immediate thermal punch you need for high-speed cycles. It’s great for thick-walled preforms. But a quick heads-up: if you’re pushing high wattage, keep your cooling blowers clean. If your fans are clogged with dust, these lamps will bake your oven housing. The build quality We use high-purity quartz glass because it can handle the shock of rapid heating and cooling without cracking. Inside, we use a halogen gas fill to stop the filament from evaporating too quickly. Basically, it means the lamp lasts longer before it finally gives up. We also obsess over the connectors—usually R7s or Sk15. We keep the tolerances tight so the lamp snaps firmly into the socket. If the fit is loose, you get arcing. And arcing will fry your sockets in a matter of weeks. Not a fun way to spend a Friday. Making your life easier At the end of the day, you just want the heat to be even. We designed these to spread infrared energy across the whole preform so you don’t end up with “cold spots” or weird wall thickness in your bottles. But here is the best part: since these are universal, you can stop hoarding ten different types of brand-specific tubes in your warehouse. You can move to one single SKU. It cleans up your shelves, simplifies your inventory, and means you aren’t waiting weeks for a specific part to arrive when you’re in a pinch.
