Getting Your PET Heat Just Right

If you’ve spent any time around PET blowing machines, you know the drill. Everything depends on that infrared energy hitting the preforms at just the right moment to soften them up before they hit the mold. If the heat is off, the whole batch is off. That’s why we built our 362mm 800W halogen lamp. It’s a simple, drop-in replacement designed for those high-cycle environments where you can’t afford any downtime. Why the size and power matter Here’s the thing: 800W packed into a 362mm length isn’t random. It’s about hitting that “glass transition temperature” fast. By using a shorter, high-wattage tube, you can blast the body of the preform with heat without accidentally melting the neck. Plus, the length is exact. It slides right into your oven rack without forcing it, which means you aren’t putting unnecessary stress on the quartz glass. The tech side of things We use a halogen cycle here. In plain English? It stops the tungsten filament from evaporating and gunking up the inside of the tube. This keeps the glass clear and the heat consistent for thousands of hours. The quartz itself is tough, so it doesn’t crack when you’re rapidly switching the power on and off. One quick tip: when you’re wiring these in,**keep your connectors spotless.**If there’s oxidation at the contact points, you’ll get localized overheating, and your lamp will burn out way sooner than it should. The trade-offs These lamps are fast. Really fast. Because they use shortwave radiation, they penetrate the plastic much quicker than those old-school ceramic heaters. You get your cycles done faster and you stop wasting energy. But, there is a catch. 800W in such a small footprint creates a lot of intense, concentrated heat. Before you fire it up, just double-check that your cooling fans are actually up to the task. If the airflow is choked, the lamp runs too hot and the filament will give up the ghost. Also, keep an eye on your voltage stability—spikes are the enemy here.

Getting Your PET Preform Heating Just Right

If you’ve ever dealt with PET blowing, you know the struggle. You need the preform to hit that sweet spot—the glass transition temperature—without accidentally scorching the plastic. It’s a delicate balance. That’s why we use halogen-filled quartz lamps. They pump out high-intensity shortwave infrared radiation, which is basically the fastest way to get that plastic ready for blowing. Let’s talk power. We build these lamps to pack a lot of punch into a small space. Depending on how long your oven is, you’re probably looking at tubes between 200mm and 500mm. We usually go with high-voltage setups (like 230V or 400V). Why? Because it lets us push more power through the filament without cranking up the current to a point where your wiring starts to melt. It gives you a concentrated heat profile, which means your cycle times drop. But a word of caution: high wattage means intense heat. If your cooling fans aren’t up to the task, you’re going to cook the lamp ends. Keep an eye on that. The build and the “swap” Inside that high-purity quartz envelope is a tungsten filament. We add halogen gas in there to stop the filament from evaporating too quickly. It keeps the light output steady and makes the lamps last much longer. When it comes to plugging them in, we stick with R7s or SK15 bases. They’re simple. They fit right into most industrial PET ovens, so when a tube finally burns out, you can swap it in a few minutes. No need to rewire the whole rack and lose an afternoon of production. Making it work in the real world These lamps are designed to hit the polymer chain of the PET preform directly. The shortwave radiation sinks in fast, so the preform doesn’t have to sit in the oven forever. This is huge because it stops that annoying “skin effect”—you know, where the outside of the plastic burns while the inside is still cold. Here’s the catch, though. Halogen lamps are fast, but they’re picky. Positioning is everything. If the lamp is even a little too close, you’ll end up with hot spots and bottles with uneven walls. Get the distance right, and you’re golden.

Introduction

We built this 670mm, 600W halogen infrared lamp for one simple reason: to drop straight into PET blowing machines and replace the standard halogen heaters. No messing around. It’s about getting heat that’s consistent, dependable, and ready to keep up with the pace of the blow molding line. And the best part? It fits into what you already have—no redesigning the reflector or socket. You just swap it in and get back to work.

Introduction

We built these short-wave, golden Heraeus quartz halogen IR dryer bulbs with one person in mind: you—the engineer running PET plastic welding. The idea is simple. Give you a blast of high-density infrared that heats the weld zone fast, over and over again, without drying out the material or wasting energy on the frame around it.

The Nitty-Gritty

When you’re welding PET, speed matters. Heat has to show up and show up fast. That’s why these bulbs are short-wave emitters. Most of their energy is packed into the near-infrared band, so the surface grabs the heat immediately and gets the weld interface up to melt temperature in seconds. The power and electrical specs are built to drop straight into industrial machines. Most run at 400V, which keeps the current draw reasonable while still delivering the wattage you need for quick cycle times. And the tube length? We set it at around 300mm because that fits snugly into compact heating heads and tight tooling spaces. Here’s the catch, though: packing high watt density into a short tube makes things hot. Really hot. Your machine needs solid airflow and smart thermal management around the socket and reflector. If you’re running full power nonstop, expect surrounding components to feel the heat—plan for heat shielding and leave enough clearance.
