On the lamination line, preheat is where you either make yield or throw it away. Uneven surface heat drags thermal stress into the press, and you end up with hairline fractures after autoclave. Ramp too slow, and the whole line sits idle, burning hours and energy for no reason. We built our infrared preheat modules to hit the thermal profile you need—shift after shift.
What matters under the hood
We run short-wave infrared quartz emitters tuned to glass emissivity, so you get fast, surface-dominant heating with minimal convection. The numbers are chosen for the floor, not a slide deck: heating rate up to 6°C/s from ambient, temperature uniformity within ±2% across the active zone, and power density of 30–40 kW/m². That gives you a clean, repeatable ramp without overshoot. Footprint matches common lamination feed tables, and the electrical integration supports 380/400 V three-phase, with IP54-rated termination for real plant conditions.
Why this plays in EVA, SGP, and PVB
In lamination, preheat has to bring the plies into a tight temperature band so the press closes clean and traps as little air as possible. Even heat cuts down bubble defects and edge slip, and it shortens the time from loading to vacuum bagging. In practice, you get faster cycles, fewer scrapped stacks, and energy use per batch that stays predictable. For automotive and architectural glass, that means consistent quality and line capacity you can actually plan around.
A few shop-floor notes
These modules drop in, but alignment and clearance are not optional. Keep the hot zone airflow clean and give it room away from shields—otherwise you get localized shadowing. Expect a short warm-up to reach setpoint stability, and keep optics and reflectors on your PM schedule. Match the module to your conveyor speed and press timing, and it performs. Just respect the thermal boundary conditions on the line.
