Stop Fighting with Uneven Bottles on Your KHS Line
Ever pull a batch of PET bottles off the line and realize the walls are thin in some spots and thick in others? It’s frustrating. Usually, it means your KHS oven has some cold spots, or your lamps have just drifted over time and aren’t hitting the wattage they used to. That’s where we come in. We make quartz heating lamps that you can just pop right into your existing setup to close those thermal gaps.
The Secret to a Perfect Stretch
If you want a bottle that stretches evenly, you need a steady infrared field. No guesswork. We use high-purity quartz glass because it lets short-wave heat pass right through. Instead of wasting energy heating up the air in the oven, the heat hits the preform directly. And here is the clever bit: we’ve tightened the way the filament is wound. Most lamps run cooler at the tips than in the middle—the “end-effect.” We’ve basically fixed that. You get a flat, consistent heat profile from one end of the tube to the other.
No Headaches During Install
Nobody wants to spend their weekend modifying sockets or rewiring an oven. Our lamps are built to fit KHS footprints exactly. Whether you’re running high-voltage or standard wattage, the internal filament is centered perfectly—down to a fraction of a millimeter. We use the same connectors you’re already used to, like R7s or SK15. You just swap them out and get back to work.
A Quick Word on Power
It’s tempting to go for the highest wattage possible to speed up your cycle times. But there’s a trade-off. When you cram more power into a short tube, things get hot. Really hot. This puts a lot more pressure on your cooling fans. If you decide to max out the heat, just double-check that your ventilation can keep up. If the oven gets too stuffy, you’ll just burn through your lamps faster. At the end of the day, it’s all about the match. When the infrared wave actually lines up with what the PET material absorbs, you stop paying for wasted electricity and start seeing consistent bottle weights every single time.
