Getting the Heat Exactly Where You Need It: Custom Contour Halogen Lamps

Let’s be honest: standard straight lamps are a pain when you’re working with curved plastic. You end up with cold spots, uneven welds, and a lot of wasted energy trying to “trick” the heat into hitting the right spot. That’s why we do things differently. We take our 240V 880W infrared lamps and actuallybend them. We shape the quartz to match your specific welding jig or PET preform. The goal is simple: keep the heat source the same distance from the plastic at every single point. No guessing. No gaps. Why the specs actually matter At 880W, these things pack a punch. We use shortwave IR, which is great because it dives straight into the plastic. It hits your target temperature fast without turning your entire machine frame into an oven. Plus, because there’s halogen gas inside that quartz envelope, the filament can run hotter without burning out. It just lasts longer. The real win here? You can throw away those clunky, complex reflectors. When the lamp follows the footprint of your part, the heat goes exactly where the weld happens. It’s cleaner, faster, and a lot more efficient. A couple of things to keep in mind Wiring these into a standard 240V industrial circuit is easy. But since we’ve bent the tube, that curve is a bit of a sensitive spot. When you’re installing them, use heat-resistant clips. Just make sure they aren’t pinching the quartz. If the tube can’t breathe as it expands and contracts with the heat, it might crack. And one last tip:don’t skimp on the cooling fans. When you’re pushing this much heat density, your housing needs to breathe. If the air stays stagnant, the heat soaks back into the electrodes and kills the lamp’s lifespan. Keep the airflow steady, and your lamps will keep humming along.

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.
