Fixing the Heat Struggle in KHS Blow Molding Lines

Ever pull a batch of PET bottles off the line only to find some are cloudy or the walls are way too thin in some spots? It’s frustrating. Usually, it comes down to one thing: your heat isn’t hitting the preform evenly. That’s why we built these 2500W IR radiators. They’re designed to plug right into Sidel-style heating arrays and fill those annoying thermal gaps that cause so many headaches. The power behind it We went with a 2500W rating because, frankly, you need the muscle. If you’re running a high-speed line, the preform spends almost no time in the oven. You have to hit that glass transition temperature now, not in a few seconds. We use shortwave infrared tech here. Instead of just scorching the surface, the heat actually sinks deep into the plastic. It’s fast. Efficient. And it keeps your production moving. Getting rid of those “cold spots” Most lamps have a habit of dying off at the ends, leaving you with uneven bottles. We fixed that by tweaking the filament winding and the quartz thickness. The result? A flat heat curve. The preform gets a steady, uniform soak from top to bottom. Plus, we use high-purity quartz so the tubes don’t just burn out the moment they hit high voltage. No fancy tools required You won’t need to rebuild your oven or spend hours on a custom install. These are spec’d for a direct fit. They use standard industrial connectors, so you just wire them up and get back to work. A quick heads-up on maintenance Here’s the thing: pushing 2500W creates a lot of heat. Your oven’s cooling system is going to feel it. If your blowers are clogged with dust or your vents are blocked, that ambient heat builds up and kills the lamps faster. Keep your airflow clean. It’s a simple step, but it saves you from overheating your sockets. Also, keep an eye on your voltage stability at the lamp head. If the power flickers, the filaments suffer. Keep it steady, and these things will last.

When the heating tunnel starts drifting, you feel it everywhere—scrap piling up, cycles slowing down, changeovers turning into panic drills. You need an infrared lamp that behaves like the original, electrically and thermally, without paying OEM prices to get it.

What matters, technically

This is a 400V, 2500W infrared lamp, built for PET preform heating in stretch blow molding. It holds repeatable output so the heating curve stays steady over long runs, and the 2500W rating lines up with what most OEM heaters are spec’d at. It uses short-wave infrared, so response is quick—tune a zone, and you don’t wait around for the thermal lag to catch up. You get consistent quartz tube clarity and stable filament geometry, which keeps energy density even across the preform shoulder and body. No surprises, just repeatable heat where you need it.
