Getting Your Reggiani PET Heat Just Right

If you’re running Reggiani machines, you know the struggle. You need your PET preforms to hit that exact glass transition temperature, but there’s a razor-thin line between “perfectly heated” and “burnt to a crisp.” We don’t just ship you a box of lamps and wish you luck. We actually tune the spectrum.

Why the “Physics” Part Actually Matters

Here’s the thing: most standard IR lamps are wasteful. They pump out energy in wavelengths that the PET plastic just ignores. It’s like trying to heat a room with a flashlight. We do things differently. We focus on the specific peaks the plastic actually absorbs. By tweaking the tungsten filament diameter and the halogen gas pressure, we shift the emission curve. The result? The heat actually sinks into the thick base of the preform without scorching the thinner walls. It’s a much more balanced bake.
