Stop Overpaying for SIG Blomax 4 Replacement Lamps

If you’re running a SIG Blomax 4 or a Krones Contiform, you know the drill. It’s a constant fight against lamps burning out, and every time you order parts from the OEM, the bill makes you wince. It feels like a tax just for keeping your machines running. We decided to fix that. We build infrared lamps that do exactly what the originals do, but without the “brand name” price tag.

Getting Your Sidel and SIG Blomax 6 Lamps Right

We built our replacement lamps to work across the whole Sidel family. Whether you’re still running those old-school SBO units or you’ve moved up to the Matrix series, these will fit. For the SIG Blomax 6 specifically, it’s all about the heat. You need that PET preform to hit the glass transition temperature perfectly—hot enough to shape, but not so hot that you’re scorching the plastic. The fit has to be spot on. If the lamp doesn’t match the original footprint, you’re in for a headache. We make sure the length and the connectors are an exact match for the Sidel gear. Why? Because nobody wants to spend their afternoon hacking away at an oven chassis just to get a wire to reach. And a word of caution: don’t mess with the voltage or wattage. If it’s even a little bit off from the original specs, you’re looking at a blown power supply or annoying cold spots in your heating zone. It’s just not worth the risk. The science part (kept simple) These lamps use shortwave infrared to punch through the PET wall fast. To handle that kind of heat, we use high-purity quartz glass. We also added a specific coating to the tube. It pushes the heat forward into the preform instead of letting it bleed backward into the oven wall. It keeps the housing from overheating, which keeps everything running smoother. Installing them without the stress The best part? You can swap these into any Sidel-compatible oven without digging into your machine settings. We obsessed over the mechanical tolerances so they just slide into the sockets. No forcing, no stressing the quartz. But here is the thing you need to watch out for. If you crank up the wattage to shave a few seconds off your cycle times, you’re putting a lot more pressure on your cooling blowers. If you’re running at peak output, double-check that your airflow is actually clear. And honestly? Dust is your biggest enemy. A dirty reflector will kill your efficiency way faster than the lamp actually wearing out. Next time you change a lamp, take a minute to give the reflectors a good scrub. It makes a world of difference in how evenly your heat hits.

Getting More Out of Your Old SIG Blomax

If you’re running an older SIG Blomax 4, 6, 8, or 10, you probably know the feeling. The machine just isn’t hitting the numbers it used to. It slows down. You lose cycle time. Most of the time, it’s because your heating elements are just tired. But here’s the thing: you don’t need to rip out the whole oven to fix it. Usually, a simple swap to higher-density infrared (IR) lamps does the trick. The Heat Factor These machines use short-wave IR to get those PET preforms soft enough to blow. Now, you have to be careful here. Your wattage and voltage need to line up with your power supply. If you go with a lamp that has a higher wattage than what came with the machine, you’ll get heat penetrating the plastic much faster. That means you can crank up the machine speed. Just keep in mind there’s a catch. More heat puts more stress on your reflectors. And if your timing is off by even a split second? You risk scorching the preform. It’s a balance. Built to Last (And Fit) We use high-purity quartz glass for our lamps. Why? Because these things go through a brutal cycle of heating and cooling, and cheap glass just warps. We also stick to R7s or SK15 connectors. A loose connection is a nightmare. It creates resistance, the terminal overheats, and eventually, you’ve burned out the socket. The best part is that these are drop-in replacements. The length and diameter are a perfect match for the SIG footprint. No rewiring the oven, no modifying holders. You just put them in and go. Putting It Into Practice Swapping these lamps is probably the quickest way to get your heating profile stable again. You’ll notice it immediately in your bottles—the wall thickness just looks more consistent. One quick tip before you start: higher-output lamps make the inside of the oven a lot hotter. Check your cooling fans. Make sure they’re clean and actually moving air. If your vents are clogged with dust, those new lamps will just bake your machine frame instead of heating the PET.
