When your blow molder goes down because a heating lamp took a dive, you don’t want “close enough.” You want the exact emitter that keeps the heating tunnel repeatable. We build quartz lamps with R7s ceramic bases, dimensioned and tuned to match OEM performance on Sidel, Krones, SIPA, Husky, and other stretch blow molding platforms. What actually matters under the hood These quartz infrared emitters are built around an R7s ceramic base and a high-purity quartz tube, so response is fast and output stays stable across the preform heating window. Typical configurations run 1200W–3000W, 100V–240V, with tube lengths matched to the OEM heating zone—commonly 300mm to 1200mm. Filament design and reflector geometry are set to match the original spectral profile, so you keep the same heating curve, thermal balance, and cycle-to-cycle consistency the machine was designed for. Why this matters on the line Preform heating is the first bottleneck on any blow molding line. A lamp that drifts throws off wall distribution, drives scrap up, and forces you to chase temperature every changeover. These R7s lamps drop in as a 1:1 fit, so you don’t have to re-tune the whole heating tunnel. The payoff: more stable preform temperature, fewer pinholes and PET degradation issues, and uptime you can actually plan around. Energy stays under control because output matches the machine’s original thermal profile, not an over-spec that just wastes power. What you need to watch on install Installation is straightforward—match the R7s pin alignment and confirm clearance around the reflector. But ceramic bases are brittle. Use a proper seating tool and torque to the machine’s specified limit; overtightening cracks the base and kills the lamp early. Also double-check socket type and voltage on your blow molder. Mismatched voltage will shorten filament life fast. And treat the heating tunnel like a system: clean reflectors and correct airflow keep the lamp performing the way it’s rated.
