Introduction
We built this conveyor infrared annealing system to solve one specific headache: getting large injection-molded parts out of the mold and locking in their material properties instantly—no waiting around for batch ovens. The whole idea is simple: a high-density infrared heating zone that slides right into your production line. Parts glide through at line speed and come out ready for the next step, without the usual pause.
The Nitty-Gritty: Power, Voltage, and Size
We went with a 400V electrical setup because it gives you stable, high-current output with almost no voltage drop, even over long runs. That translates to fast heat-up—crucial when you need to hit annealing temperature quickly and hold it steady. The lamps are sized to fit the part, usually around 300mm long. That keeps the heating zone compact, so you can slip annealing into an existing line without tearing the plant apart.
Material and Design: The Details That Matter
We use halogen-filled quartz tubes because they handle repeated heating and cooling without complaining, and they keep output steady over time. The tubes are coated to focus the energy where it’s needed and cut down on waste—so your heating stays consistent, no hot and cold surprises. For installation, the lamps use R7s bases. They drop in and lock in place without any custom fixtures. When a lamp burns out, you swap it in minutes and keep the line moving. No drama.
What It Feels Like on the Floor
On-line annealing means the part never leaves the flow. It goes straight from the mold into the infrared zone and back onto the conveyor—no batch delays, no extra handling. For large injection-molded components, that means shorter post-processing times and more open floor space, because you’re swapping a bulky standalone oven for a slim, in-line module. But here’s the catch: the heat is concentrated. That means you need cooling and shielding sized right around the zone to protect nearby equipment and keep things comfortable.
