On the blow molding floor, preform heating is where the money is made—or lost. When temperatures run uneven, setpoints drift, and lamps burn out early, the heating tunnel turns into a black box. You feel it in fluctuating bottle weight, flash, and unplanned line stoppages. We build infrared emitters for PET blow molding machines to cut that uncertainty out.
What matters, technically
We supply short-wave infrared emitters engineered to match the OEM heating profiles of Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB blow molders. The specs are job-specific: 230V or 400V configurations, fast-response quartz elements, and R7s bases for a drop-in fit. Output is tuned to heat preforms quickly without scorching the neck finish, and the geometry is calibrated to match tunnel lane spacing and reflector assemblies. We do 1:1 parameter matching—wattage density, focal line, and spectral response—so your existing PID and zone controls stay exactly as they are.
Here’s why this matters on the floor: fast, repeatable heating is the lever that drives cycle time, scrap, and uptime. Our emitters hit setpoint faster, hold temperature tighter across the tunnel, and stay stable even when line speeds shift. The payoff is fewer temperature-related rejects, more consistent bottle wall distribution, and less energy wasted chasing drift. We’ve got units running 5,000+ hours with less than 5% output drop, which means fewer lamp changes and less pressure on maintenance windows.
Installation is straightforward on standard R7s sockets, but reflector cleanliness and alignment matter. If reflectors are pitted or mis-set, you’ll lose irradiance and see uneven heating even with a perfectly matched lamp. Also, verify voltage and tolerance at the terminal block—mismatched voltage will shorten element life. Give the emitter proper thermal clearance, and keep the heating zone free of dust and oil. When those basics are covered, the upgrade is a direct swap with predictable performance.
