The glass comes out hot, still holding its shape, waiting to set. Then the real work starts—cooling. If the cooling is off, that thermal stress rides right into the next station. You end up with warp, optical distortion, and scrap. In tempering and bending, cooling isn’t just waiting around. It’s controlled heat extraction, and the cooling fan is what makes the profile repeatable. The oven heats fast, sure, but the cooling has to be faster—and steadier—than most people expect. When the airflow is wrong, the top surface cools before the bottom, the edges cool before the center, and the bow shows up before the lehr can even smooth it out. You chase set points, tweak ramps, and the <a href="https://henruite.com">reject</a> bin still fills up. The fix isn’t more heat. It’s the right airflow, delivered where the glass needs it, exactly when it needs it.</p>
