Getting Your IR Preheating Right for Silk-Screened Glass

When you’re moving glass straight from silk-screening into the tempering furnace, you’re walking a pretty thin line. You need enough heat to set the ink and get the glass ready, but if you push it too far? Your crisp patterns start blurring and the ink bleeds. It’s a mess. That’s why we lean on short-wave infrared (IR) lamps. They hit that sweet spot. Keeping Your Patterns Sharp The trick is to heat the surface fast without soaking the whole slab of glass too early. Short-wave IR does exactly that. It flashes off the solvents and locks the ink in place before the glass even hits the main belt. But be careful with your settings. If your lamp wattage is cranked too high for your conveyor speed, the ink starts to migrate. You lose that sharp edge. We set these lamps up to put the heat exactly where it belongs: right on the ink layer. The Gear and the Setup We usually go with quartz halogen tubes for these CNC setups. Why? Because they can handle the shock of turning on and off rapidly without popping. We use standard R7s or SK15 connectors, too. That way, when a tube finally burns out, you can just pop a new one in and get back to work. Now, if you’re working with thick glass, you’ll want high-wattage configurations to get the heat density you need. Just a heads-up: those arrays put off a ton of ambient heat. Make sure your cooling fans and vents are up to the task, or you’ll end up frying your CNC electronics. Why This Actually Works Ditching the old convection ovens for IR lamps saves a massive amount of floor space. Plus, they’re instant. They keep pace with your CNC cutter perfectly. The best part is that the glass stays warm from the moment it’s printed until it hits the furnace. It takes the pressure off your main furnace and keeps those nasty internal stress fractures from happening. It just flows better.
