SIG Blomax 10 Replacement Lamp: Built to Be a Perfect Match
We built this replacement lamp for one reason: it was made specifically for the SIG Blomax 10. It all comes down to one thing—rock-solid power. You need consistency to keep heating even on those SIPA rotary lines. The specs are simple: a 400V, 2500W halogen infrared lamp, 300mm long. That wattage and voltage? Not random. It’s the machine’s thermal budget. Get it exactly right, and the control system works like it should. Swap in a weaker lamp, and the whole system falls flat. Go too strong, and you risk tripping protections and cooking parts.
Why Halogen and the R7s Connector?
This is a shortwave halogen infrared lamp. The halogen cycle does a neat trick—it keeps the quartz envelope cleaner, which means the output stays steady over the life of the tube. Less drop-off. No drift in your heating profile. The quartz body is tough enough to handle the on-off cycling of a rotary machine, where the lamp fires up and down again, again and again. And the R7s connector? It’s a direct, drop-in fit. It handles the 400V load with a solid two-contact grip that won’t spark under vibration. Installation is straightforward. Line up the pins, seat the tube, and lock it down. No rewiring. No custom brackets.
What It Does on a SIPA Rotary Line
On a SIPA rotary machine, every preform needs the same heat. If the lamp’s output wobbles, you get uneven stretch and uneven wall thickness. This replacement lays down uniform shortwave infrared across the 300mm active zone, so every preform sees the same heat profile. The payoff? Repeatable heating and fewer rejects. Here’s the trade-off: 2500W at 400V means serious heat density. So your machine’s cooling and airflow need to be in good shape. Keep the reflector clean. And check the voltage at the socket. If the line voltage sags, the lamp underperforms, and the heating drift comes back. This is a direct-fit replacement built to keep your process steady, cycle after cycle.
The Reality: Match the Power, Keep the Cooling Sorted
A 400V, 2500W tube delivers the heat density you need for fast, consistent preform heating. It also runs hot. Make sure the blower and ducting are clear, and that the lamp sits square in the focal path. Before you install, run a power check at the socket. A true 400V supply keeps the lamp in its sweet spot. That means fewer early burnouts and steady output shift after shift.
