Out on the line, a PET bottle lives or dies in the heat. When the heating tunnel drifts off-spec, preforms stick, start to crystallize, or blow unevenly, and you burn minutes every time you change over. We built our infrared heater lamps and wiring to keep every preform in the right thermal window—without paying OEM markups.
What matters under the hood
Our quartz halogen IR emitters put out stable, short-wave energy tuned for PET: fast ramp-up, tight control across the heating zones. The lamps are matched for wattage, voltage, and dimensions to fit Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB blow molders.
Wiring uses high-temperature insulation and secure connectors—often R7s-type interfaces—so the lamp seats clean and stays aligned. We hold filament geometry and reflector placement consistent to keep the spot profile even. That matters when you’re heating thin necks and thick body walls in the same cycle.
Why this matters in stretch blow molding
Yield in stretch blow molding rides on heating uniformity. With these lamps, temperature holds steady across the tunnel, so you see fewer pinholes, less wall thickness variation, and less scrap from preforms that run too hot or too cool.
Fast response cuts warm-up time after a restart, and stable output trims energy use by preventing overshoot. OEM-grade materials and a 1:1 fit mean you can swap lamps in a quick maintenance window, keep the same heating profile, and keep the line moving.
A few shop-floor notes
Installation is straightforward, but the tunnel is hot and tight. Double-check lamp orientation and reflector position to avoid shadowing, and verify voltage at the connector under load.
These are high-temperature parts—gloves on, and don’t touch the quartz surface.
If you run 24/7, plan replacements around scheduled stops. Even durable IR lamps have finite hours, and preventative swaps keep output consistent.
