Infrared lamp 400V 2500W for SIPA

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.

SIPA SFR 12 infrared radiator

On the SFR line, the heating tunnel is where you stop chasing scrap and start making money. If infrared output starts drifting, preforms heat unevenly. Walls thin out, and the machine slows down just to keep things from going sideways. The SIPA SFR 12 infrared radiator is built to drop in as the original emitter, without having to re-tune the whole oven. You get stable heat back, repeatable timing, and consistent bottle quality. What matters, technically The SFR 12 is a short-wave infrared radiator made for the SIPA SFR blow molder. Quartz tube, halogen filament—fast response and tight control in the heating tunnel. The mounting, wiring, and spacing match the OEM, so the reflector geometry and focal line stay where they should. In practice, that means the intended heat profile across the preform neck and body, without hot spots or cold bands. Why it works on the SFR Put the SFR 12 in, and warm-up is quicker, you tweak parameters less, and uptime goes up. Plants on the SFR often see the heating section’s energy use drop 12–18%, because the emitter hits setpoint fast and holds it without a lot of overshoot. After a jam clear, cycle recovery is faster. Scrap from uneven stretch drops, because the preform lands in the right temperature window every time. Lamp life typically lands around 5,000 hours, so you change them less often and keep maintenance predictable. The practical details This is a direct-fit replacement, but double-check voltage, connector type, and clamp orientation against your machine spec before ordering. The quartz tube doesn’t like rough handling—clean with a lint-free cloth, never touch the glass with bare fingers, and confirm reflector alignment after installation. Keep the power clean, too. Voltage sag and spikes shorten emitter life, so a stable supply is worth a quick check.

SIPA SFR 6 infrared lamp bulb

On the floor, the SIPA SFR 6 runs to its own beat. But when preform heating starts drifting, the blow station struggles to keep up—light bottles, short shots, and resin going straight into the scrap bin. The heating tunnel is where the whole process either stays honest or falls apart. What matters under the hood The SIPA SFR 6 infrared lamp bulb is built around short-wave quartz infrared emitters, chosen for quick response and repeatable output. You’re looking at 2400–3000 W, matched to the machine’s voltage and heating zone layout. The R7s base and standard length are meant to drop straight into the existing lamp holders and reflectors—no mods to the heating tunnel. In practice, that translates to faster warm-up, stable temperature across the preform wall, and less cycle-to-cycle drift. Why this matters in stretch blow molding The preform surface temperature window is tight. When the infrared output is properly matched to the SFR 6, you get even heating across the neck and body, so the stretch ratio stays consistent. That means fewer rejects, more predictable bottle weight, and a line speed you can actually plan around. Energy use comes down because the emitter heats on demand and holds set point without overshooting. Lamp life stretches compared to weaker options, so you spend less time on changeovers and more time making good bottles. The details that keep it honest Installation is straightforward, but alignment is where people get tripped up. Even a slight mis-seat in the R7s socket can create uneven heating and shorten lamp life. Keep the reflectors clean, and keep an eye on heating tunnel airflow—too much draft and the temperature profile goes sideways. And match the bulb to the exact SIPA SFR 6 configuration. Swapping in a non-matched emitter changes the thermal profile and bites into bottle quality. Treat the details right, and the lamp does its job.
