Getting Your Infrared Lamp Layout Right for Resin Curing
Curing brake pad resins is a finicky process. If the heat doesn’t hit every spot just right, you’re in trouble. When we build custom heating walls for paint booths or curing ovens, the real headache is that no two parts are the same. If you just throw in a standard lamp layout, you end up with the classic nightmare: some spots are freezing cold, and others are burnt to a crisp. The secret is in the vertical layout. You can’t just space your lamps evenly and hope for the best. Different vehicle shapes create “thermal shadows”—basically, blind spots where the heat can’t reach. We handle this by mapping out the vertical spread based on how tall the part is and how far the lamp sits from the surface. For those big chassis, we pack more short-wave IR lamps into the center zone. It makes up for the heat that naturally leaks away. Plus, we don’t run the whole wall as one big block. We split it into independent vertical banks. This lets you crank up the power for the bottom section—where those heavy castings live—while keeping the top section dialed back. It stops the top layer of resin from flashing too fast and ruining the finish. The trade-off with high heat Now, high-wattage quartz lamps are great because they get the resin polymerizing fast. But there’s a catch. If you jam too many lamps into a tight space to hit your temperature goals, the oven shell gets incredibly hot. If there isn’t enough airflow around the tube ends, the lamps will just burn out. It’s a waste of money. You’ve got to make sure your ventilation is actually moving air across the reflectors, or you’re just cooking your own filaments. Making it flexible We build these walls as modular inserts because things change. Maybe you switch to a different vehicle size next year. Instead of ripping out the whole wall, you just shift the brackets or swap in different length tubes. Pair that with independent PID controllers for each zone, and you’ve got a setup where the resin cures evenly from top to bottom. No matter what the part looks like, it just works.
