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.
