When your SIPA stretch blow molder is running, you need preform heating that holds steady. A weak or drifting emitter doesn’t just throttle line speed—it drives scrap and keeps you from landing on the setpoints you need. You want a lamp that matches the machine’s power, geometry, and control behavior, not a guess that leaves you tweaking the heating tunnel every shift. What matters under the hood We build this infrared lamp for SIPA blow molding machines: 400V, 2500W, so you get the heat density required for fast, repeatable preform heating. The quartz envelope responds quickly, heating up fast and cooling down fast when you’re doing changeovers. The spectral profile is stable and tuned for PET, so absorption across the preform wall stays predictable—no more chasing hot and cold spots. It uses a standard R7s base, so it drops straight into the existing socket without rewiring or custom mounting. Why this fits a SIPA blow molder On a SIPA, the heating tunnel is a tight system. Reflectors, spacing, and airflow are all set to a specific energy budget. A 400V, 2500W lamp keeps that budget intact, so the preform hits the right temperature distribution before it stretches. The payoff shows up as fewer pinholes, better weight control, and less trim. Energy use stays stable because the output matches the machine’s design—no over-firing to compensate for a weak lamp. In the field, we see stable output over 5,000+ hours, with minimal drift, so your process window stays consistent. Field notes that save you trouble Installation is straightforward, but alignment is everything. Even a lamp that’s slightly off-seat shifts the hot zone, and that shows up as edge thinning or inconsistent blow-up. Verify voltage at the terminal and match the lamp to the reflector type—short-wave emitters behave differently depending on the reflector coating. Handle it with clean gloves; oils on the quartz create hot spots and shorten life. If you’re running 24/7, plan replacements around scheduled stops, and swap one lamp at a time. That avoids sudden heating shifts that force a recalibration.
