On the plant floor, the heating tunnel is where the clock really starts ticking. Preforms running cool give you streaks, weak stretch, and bottles that miss the spec. Run them too hot, and you’re burning material and chasing rejects. On your Krones Contiform 3, that infrared lamp isn’t just another part—it’s the control point that keeps every cycle honest and repeatable. What matters under the hood We build the Contiform 3 infrared lamp as a direct-fit emitter, matched to the machine’s heating geometry. It’s a short-wave quartz halogen design, so the energy lands right in PET’s absorption band. Filament layout and reflector geometry focus the heat onto the preform shoulders and body, giving you even temperature without hot spots. Output is tuned to the Contiform 3 power envelope, and the lamp comes with the correct R7s base, proper arc length, and leads sized for the existing socket and wiring path. Why it earns its keep on the Contiform 3 Stretch blow molding demands that the preform hit a tight temperature window before it reaches the blow station. This lamp restores the original heating profile the Contiform 3 was designed to run, so you get faster stabilization after startup and steadier temperatures across long runs. That means fewer pinholes, more uniform wall thickness, and less scrap. Energy use drops because the emitter heats on demand and cools quickly, and stable output keeps you from overdriving the tunnel just to compensate. Field-level practicalities Installation is straightforward, but treat the lamp carefully. Keep oils and contaminants off the quartz, and verify socket alignment and voltage—mismatched voltage will shorten filament life and drift the heating curve. Typical service life supports multi‑thousand‑hour runs, but plan replacements during scheduled stops so the heating zone stays balanced.
