Getting Your SIG Blomax 6 Back Up to Temp
When you’re running a SIG Blomax 6 or a similar PET blowing setup, the last thing you want to deal with is a lamp that “almost” fits. We’ve spent a lot of time making sure our infrared lamps are true drop-in replacements. It’s not about trying to make one lamp fit every machine on earth. It’s about getting the electrical and physical measurements exactly right so you can just plug it in and get back to work.
The Nitty-Gritty on Power
Here is the thing: heating PET preforms is a balancing act. You need enough punch to soften the plastic quickly, but not so much that you melt the neck. We use high-wattage shortwave lamps to get that heat exactly where it needs to go. But a word of caution—if you’re pushing a 2500W tube into a system with weak cooling, you’re asking for trouble. Your blowers have to be able to handle that kind of heat, otherwise, you’ll burn right through your lamp holders.
What’s Under the Hood
We stick with high-purity quartz glass and halogen gas. Why? Because it makes the filament last longer. We also apply specific coatings to these lamps. Instead of just scorching the surface of the plastic, the heat actually penetrates the wall of the preform. As for the connection, we use standard R7s or Sk15 connectors. You won’t have to mess around with your machine’s wiring or hunt for adapters. It just works.
Real-World Advice
Let’s be honest: OEM lead times are a nightmare and the costs are usually eye-watering. Our lamps solve that. Since the dimensions and electrical ratings match your specs, you don’t need custom brackets or voltage converters. You get the right temperature, right now. One quick tip before you install them:**Clean your contact points.**If those pins are oxidized, they’ll create hot spots. I’ve seen a brand-new lamp die in a few hours just because the connection was dirty. Give them a quick wipe, and you’re good to go.
