Preforms sit under lamps that pull heavy current, dump excess heat into the machine frame, and force the cooling system to work overtime. When those lamps don’t pull their weight, you see it fast—stretch marks, uneven wall thickness, and rejects that cost more than the electricity. We built our infrared heating approach around one plant-floor truth: energy use in blow molding comes down to how cleanly you turn electricity into the exact heat profile the preform needs, and how easily you can swap the emitter without re-engineering the machine.</p>
