The M-Shape Halogen Heat Lamp: The Heartbeat of Your PET Bottle Machine

Let’s talk about the workhorse of your PET bottle blowing setup: the M-shape halogen infrared heat lamp. We designed this thing from the ground up to slide right into your machine as a direct replacement for the standard heaters. Its whole job is simple—deliver that intense, focused heat that makes PET preforms soften up, nice and even, in a flash.

What’s Under the Hood: Power, Voltage, and Size

Here’s the specs, but let’s make them real. This lamp runs at 2500W and 400V. Why so much power? Because your blow molding cycles demand it. That power is packed into a 300mm tube with that signature M-shape, giving you a compact profile that fits into tight spots without ever skimping on the heat. And it’s fast. We’re talking heat-up times under three seconds. That keeps your cycle times tight and your production moving. But here’s the thing—that kind of power draw means your machine needs a beefy electrical setup and proper cooling around the lamp. It keeps the surrounding components from getting too hot to handle.

The Build: Halogen Tech, Quartz, and a Simple Connection

Inside, you’ve got a shortwave halogen infrared emitter, all sealed up in a quartz tube. The halogen cycle is the secret sauce—it keeps the filament stable even when it’s screaming hot, so the output stays consistent over the lamp’s entire life. The quartz tube itself is a tough cookie. It handles the thermal shock of being switched on and off, over and over, without breaking a sweat. Plus, the special coating on the tube is tuned to match the wavelengths that PET absorbs best, which makes the whole heating process way more efficient. And the best part? It uses an R7s connector. It’s the standard two-pin setup, which means swapping it out is a breeze. Just slide it in and wire it up—it’s a true drop-in replacement.

How It Feels on the Production Floor

On the line, this lamp lives in the preform heating station. It’s got one critical job: get the surface of the preform heated uniformly before it gets stretched. The M-shape focuses the heat exactly where you need it, which helps prevent those nasty hot spots and keeps you from scorching the preform. Because it’s built as an OEM component, it matches the factory mounts and spacing perfectly. That means changeover is quick, and downtime is minimal. You can count on stable output through thousands of cycles, but let’s be honest—running at this wattage and cycling that fast puts a strain on any infrared element. So, it’s always smart to keep a spare on hand.
