Stop Fighting Your SIG Blomax 4 Heat Distribution

If you’ve run a KHS-based blow molding line, you know the headache. One minute everything is fine, the next you’re staring at bottles with uneven walls or that annoying pearlescence. Once your thermal field shifts, your scrap bin starts filling up fast. It’s frustrating. That’s exactly why we built our replacement lamps for the SIG Blomax 4. We wanted to kill those distribution gaps once and for all. The secret is in the winding. Most generic lamps have loose filament winding. That leads to “cold spots” that ruin your consistency. We did things differently. We tightened the tolerances on the winding to make sure the infrared heat is steady from one end of the tube to the other. They’re designed as a direct swap. We matched the wattage-to-length ratio perfectly, so the machine keeps the heat profile it was born with. Built for the grind. Industrial blow molding is brutal on equipment. The rapid cycling can kill cheap glass. We use high-purity quartz because it actually lasts. Depending on your oven, these come with R7s or Sk15 connectors. You just pop them in. No messing around with sockets, no custom wiring. Plus, we use a halogen cycle inside the tube to stop the filament from evaporating too quickly. It just means you aren’t climbing a ladder to change bulbs nearly as often. One thing to keep in mind… Higher heat density is great because it speeds up preheating. But there’s a catch. More energy in the preform means your oven’s ventilation has to work harder. If you go with the high-output lamps, just double-check your cooling blowers. You want to make sure they can handle the extra heat so you don’t bake your machine frame. At the end of the day, these tubes perform just as well as—and sometimes better than—the OEM versions. You get the same deep IR penetration, but you aren’t paying that “original equipment” tax. It’s a simple swap that finally stabilizes your heat.

Introduction

We built this replacement lamp for one reason: to fit your SIG Blomax 4/6/8/10 like it was born there. Whether you’re moving from the older SBO models to the new Matrix line, it just works. No rewiring. No machine tweaks. No messing with the socket. It drops in the same way the original did, so you’re back up and running without the headache.

The Nitty-Gritty

This isn’t a run-of-the-mill bulb. It’s engineered to handle the heat and power needed for PET blowing. So we matched the 400V input to the Blomax electrical setup, keeping the current draw exactly where your machine expects it. And the 2500W output gives you the thermal punch to heat preforms fast and evenly. Size matters, too. At 300mm long, the tube fits the tight heating zone of the Blomax series like a glove. That length gives you even coverage across the preform. Cut it short, and you’ll get hot spots. Make it too long, and it won’t even fit the chamber.
