Fixing Those Pesky Cold Spots in Your SIG Blomax
If you’ve ever stared at a batch of bottles with uneven walls or weird deformations, you know the frustration. It usually comes down to one thing: your heating isn’t even. When those KHS/SIG Blomax machines have “cold spots,” your scrap pile grows and your mood drops. We built our replacement lamps to stop that. We focused entirely on how the infrared heat actually hits the plastic, making sure it’s precise and consistent. The nitty-gritty on the hardware Whether you’re running a Blomax 4, 6, 8, or 10, you need lamps that can push high wattage without just burning out the filament. We make sure our tubes match your original equipment’s voltage and length exactly. That means they just slide right in. No fuss. Now, heating PET preforms quickly takes a lot of energy, which can actually make standard quartz tubes bow or warp. To stop that, we use a heavy-wall quartz. It stays straight, stays strong, and handles the heat. No more “hot stripes” Here’s the thing about standard clear lamps: they often create these intense “hot stripes” on the preform. That’s how you end up with pearlescence or, worse, burnt plastic. We fixed this by adding specific coatings that diffuse the energy. Instead of a harsh beam, you get a spread of heat across the whole surface. And don’t worry about the installation. The connectors fit your existing sockets perfectly. You won’t have to touch your wiring or spend your afternoon rewiring the oven. Real talk from the shop floor Better heat uniformity means less waste. It’s that simple. But a quick heads-up: if you’re cranking up the heat density to shave time off your cycles, your ventilation has to keep up. If your cooling fans are clogged with dust, even the best lamp in the world will overheat the housing. Give your fans a look. We’ve seen these tubes hold their own against the cheap imports. They stay stable much longer, so you aren’t constantly tweaking your oven settings every couple of weeks. Just pop them in, set your profiles, and let them do their thing.
