On a Krones Contiform blow molder, uneven preform heating shows up fast—off-center bottles, blown-out shoulders, and a line that never stops chasing setpoints. We built our Contiform white-coating IR radiator as a straight swap for the OEM heating element: same geometry, same output, so the heating tunnel runs the way the machine was designed. The core is short-wave infrared inside a white-coated quartz envelope, sized and wired for the Contiform tunnel and standard lamp holders. The white coating shifts the emission curve, cutting down on glare and evening out reflector surface temperature. That helps keep the preform skin temperature profile repeatable. We match the original lamp wattage and length, and spec the filament layout and terminals so the power delivery lines up with the machine’s control strategy. Here’s what that buys you on the floor. Stable heating lets you hold stretch blow molding windows without constantly trimming offsets—less scrap, and cycle time stays where it belongs. Energy use drops because the emitter hits target fast and holds it with tight control, and the white coating keeps the heat focused where it needs to be. Replacement is straightforward—same mounting, same connections—so downtime stays short. Installation note: keep the reflector clean and dry, and make sure the lamp seats squarely in the holder. On Contiform lines that run hot and dusty, set a regular inspection interval. If the reflector degrades, heating uniformity drifts.
