On the floor, the Contiform S keeps your stretch blow molding humming, and the heating tunnel is where the whole cycle sets its tone. When a lamp burns out, you don’t just lose a bulb—you lose predictable preform temperature, stable stretch ratios, and consistent bottle weight. Throw mismatched emitters into the mix and the heater zones go out of balance. Rejects climb, and those re-heats chew straight into uptime. What actually matters under the hood We build this replacement to match the Contiform S heating system: short-wave infrared halogen emitters, in the standard wattage and voltage configurations. The quartz tube, filament geometry, and R7s connector are dimensioned to drop into the existing sockets—no rewiring needed. Each unit is tuned for repeatable spectral output, so the preform sees the same heat profile across the tunnel: no hot spots, no cold seams. Why it holds up in production With this lamp, you keep the original heating logic intact, so cycle times stay stable and bottle quality doesn’t drift. It’s engineered as an OEM-quality alternative, giving you the same control over preform heating without the OEM price. In practice, that translates to fewer temperature-related rejects, steadier output per hour, and a maintenance plan you can plan around. Units are running 5,000+ hours with less than 5% output drop, and the replacement cost comes in well below going through the original supplier. A few shop-floor notes Installation is straightforward: verify voltage, check connector alignment, and make sure the lamp is positioned correctly in the reflector. Halogen emitters run hot, so keep the tunnel clean and airflow where it should be—protects the lamp and keeps preforms consistent. This lamp is built as a direct replacement for the Contiform S, but always cross-check the exact wattage and length against your machine’s current configuration before ordering.
