On the blow molding line, uneven preform heating doesn’t just throttle output—it shows up as scrap and weight swings from bottle to bottle. When the heating tunnel can’t deliver the temperature profile the mold actually needs, you end up chasing micro-adjustments instead of running the machine the way it was designed.

What matters under the hood

We build custom infrared heaters for blow molding machines, and we match the OEM’s key parameters so the lamp fits the machine—period. That means controlling the wavelength choice (short-wave halogen or medium-wave quartz emitters), filament geometry, and power density to line up with preform wall thickness and cycle time. Each emitter is engineered to a target voltage and current curve, with R7s or other connector types that mate cleanly to the existing socket. We tune the spectral output so the PET surface absorbs heat efficiently, while keeping overheating in check to avoid crystallization.
