You&rsquo;re working with a tiny window of temperature. Go too hot? You&rsquo;ll scorch the coating or warp the aluminum. Go too cold? The coating won&rsquo;t stick, and you&rsquo;ll end up with cans rusting in the wild. Neither is a great look.</p> <h2 id="how-we-handle-the-heat">How we handle the heat</h2> <p>Instead of tossing the whole can into a massive convection oven, we use short-wave infrared (SWIR) modules. Think of it like a laser instead of a space heater. We can focus the energy on a spot just a few millimeters wide. By tweaking the wattage and the focal length, the heat hits exactly where the coating is. It happens in milliseconds. The coating cures, but the rest of the can stays cool.</p>
