When the heating tunnel on your SIPA stretch blow molder starts drifting, preforms come out uneven. You’re suddenly dealing with thin walls, flash, or a line that can’t hold pressure. The fallout is scrap, stops, and overtime. We built the 400V 2500W infrared lamp for SIPA to replace the original spec without cutting corners, so you can get the heat profile back under control.
What matters, technically
This is a 2500W short-wave infrared emitter, engineered for 400V line voltage. The quartz tube heats fast, and the response time matches the timing of SIPA heating cycles. It uses the standard R7s connector and fits the same physical envelope as the OEM lamp, so it drops straight into the existing holders and wiring. We match the filament layout and spectral output to the original, so the preform skin heats consistently—no scorching, no cold spots.
Why it works on SIPA machines
The lamp is designed specifically for SIPA machines, including Matrix and the newer X-Series platforms. It also fits SIPA lines that run high-output heating zones, so you can standardize one lamp across multiple blow molders. With stable output, you can hold tighter wall thickness and keep bottle weight where it belongs. The 400V rating reduces current draw compared with lower-voltage alternatives, which lowers conductor stress and helps keep the heating tunnel cooler at the busbars.
The details that make the difference
Installation is straightforward, but alignment is critical. If the lamp is off on focal distance to the preform, you’ll see banding and thickness swing. Verify the holders are clean and the lamp is seated squarely. Confirm the machine control is set to the correct voltage, and make sure the reflectors are intact—cracked reflectors scatter energy and change the heat pattern. This lamp is rated for 400V—don’t run it on mismatched voltage. Plan replacement during a scheduled stop so you don’t get caught by unplanned downtime.
