Stop Fighting Your SIPA Heating Profiles
Ever feel like you’re constantly chasing your tail with a SIPA rotary machine? One minute everything is fine, then suddenly you’ve got wall thickness issues or bottles bursting on the line. It’s frustrating. Usually, the culprit is something simple: replacement lamps that aren’t actually a match for the originals. When the power specs are off, your heat distribution goes sideways. That’s why we build our lamps for the SIG Blomax 6 to be a 1:1 power match. We want your heat profile to stay flat across every single zone, without the headache.
Why “close enough” isn’t good enough
Here’s the thing about physics: if you swap a factory lamp for a generic one and the wattage is even slightly off, you’ve changed the infrared wavelength. Even a tiny 5% difference forces your operators to start messing with oven timers and temperatures. That’s how you end up with “hot spots.” We spec our tubes to hit the exact voltage and wattage the Blomax 6 expects. This means the energy hitting that PET preform is exactly what it should be. No guessing. No tweaking.
Built for the real world
We use high-purity quartz for these shortwave infrared lamps. Plus, we added specific coatings so the heat actually goes into the preform instead of just warming up the oven walls. And because nobody wants to spend their afternoon rewiring sockets, we made these drop-in replacements. They fit the footprint perfectly. You just pop them in and get back to work.
A quick tip from the shop floor
High-wattage lamps are great because they give you the heat density you need for fast cycle times. But there’s a catch. Running these lamps at 100% puts a lot of stress on your oven’s cooling fans. If your ventilation is clogged or acting up, these tubes are going to burn out way faster than they should. Keep that airflow clear, and your lamps will last much longer. When your lamps actually match your machine, the guesswork disappears. You can stop fiddling with settings and just hit your production targets.
