Replacement lamp for SIPA blow molding

Introduction

We built this infrared lamp for one reason: to finally end the heating roller coaster on your SIPA rotary blow molding machine. It’s all about giving you steady, predictable heat. No more wild swings that leave your PET preforms underdone or scorched. This lamp was designed to match the original specs exactly, so you get the kind of consistent output that keeps things running smoothly.

The Power, Voltage, and Fit

Here’s the thing: this lamp doesn’t just work with your SIPA machine—it was born to work with it. It’s built to run at 400V, with a serious 2500W punch. That kind of power gives you the concentrated heat you need to get PET heating up to speed, fast. And the 300mm length? Not random. It’s cut to match the exact heating zone, so the infrared energy blankets the preform evenly. Get the length or power wrong, and you’re asking for trouble. You’ll see hot spots and weak spots, which drag out your cycle time and send more scrap down the line.

SIPA SFR 12: The Retrofit Engine for Blow Molding Output

Ever looked at your old blow molding machine and thought, “She’s got plenty of life left in her, but she’s just not keeping up”? That’s exactly the problem we built the SIPA SFR 12 infrared heating lamp to solve. We designed it for one simple mission: to bring your aging equipment back to life. The big question, of course, is whether a simple replacement lamp can really make that much of a difference. The answer is a quiet, confident yes. It comes down to the engineering. This lamp slides right into your existing fixtures, swapping out the old heaters without forcing you to scrap the whole line.

SIPA SFR 10 infrared radiator

On the blow molder, the day is won or lost in preform heating. If the heating tunnel can’t hit and hold the right temperature profile, you’re staring down uneven wall thickness, blown bottles, and scrap piling up. On the SIPA SFR series, the SIPA SFR 10 infrared radiator is built to keep that tunnel stable, shift after shift. What matters under the hood The SFR 10 is a short-wave infrared emitter—quartz tube, halogen filament—tuned for fast response and tight thermal control in preform heating. It runs on the standard voltage the SFR is spec’d for, with power density calibrated to the typical preform wall thickness and cycle times you see in stretch blow molding. The R7s connector and footprint are 1:1 with the OEM layout, so you drop it in without rewiring or tweaking brackets. In practice, that means the heating tunnel recovers fast after a jam clear and repeats the same profile, bottle after bottle. Why it fits the SIPA SFR environment This radiator was designed for the SFR’s real-world conditions. The wavelength and power profile pair cleanly with PET preforms, so surface heat penetrates quickly without scorching. The payoff: fewer temperature swings, more consistent biaxial stretching, and fewer pinholes. Startup recovery is quicker, changeovers throw off less scrap, and output stays predictable. Energy use drops, too—the emitter heats on demand and cools fast, so you don’t carry the idle losses you get with older, slower heaters. The practical bits Installation is straightforward, but the heating window is tight. Double-check the voltage and phase match your SFR unit, and verify reflector alignment—misalignment throws off the profile and drives uneven heating. Keep the quartz tube clean and inspect the R7s contacts for oxidation; contamination and poor contact are the two usual suspects when life comes up short. Expect consistent output for 5,000+ hours under normal duty cycles, and plan replacements during scheduled maintenance so you don’t get blindsided by downtime.
