Replacement lamp for SIPA blow molding

Thu, 09 Jul 2026 12:29:50 +0800

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.

Chumpower blow molding heater lamp

Introduction

Here’s the story behind the Chumpower blow molding heater lamp: we took the same heating power we used to supply to the big OEMs and made it available for every independent blow bottle shop. It’s built to be a direct, drop-in replacement for standard PET heating systems. The goal? Give you rock-solid heat, every time, without making you sacrifice cycle speed or material quality.

Let’s Get Into the Details: Power, Voltage, and Size

At the heart of this lamp is a 400V, 2500W halogen heating element, all wrapped up in a 300mm quartz tube. That power level wasn’t chosen by accident. It’s exactly what you need to heat PET preforms fast enough to keep your production line moving at its pace. And the 300mm length? It creates a stable heating zone that just fits right into the layout of most blow molding machines. Going with 400V also helps by lowering the current draw compared to lower-voltage options. That means less stress on your wiring and less heat building up at the terminals. But let’s be real—this is a heavy-duty load. You’ll want to make sure your electrical setup and cooling are up to the task. It keeps the lamp and the machine’s electrical panel running at a safe, cool temperature.

Husky blow molding machine heater tube

On a Husky stretch blow molder, the heating tunnel is where the money is made—or lost. Underheated preforms? You get crystallization and stress marks. Overheated? They fold around the stretch rod. When the heater tube starts to drift, you end up chasing scrap, throttling the line back, and paying overtime just to keep output moving. We built the Husky blow molding machine heater tube to break that cycle. What matters under the hood We match the OEM footprint and interface—R7s connector, exact tube length—so the lamp sits in the reflector the same way every time. The quartz envelope runs at the watt density Husky specifies, giving you fast-rise infrared response that holds preform wall temperature steady across the heating zone. We use short-wave emitters tuned to PET absorption, so the energy goes into the preform, not into warming the machine frame. Why this replacement behaves differently on the line With this tube in, heat-up is quicker and the heating profile settles fast. In real terms, that means fewer temperature-related rejects and more consistent bottle weight. Energy use drops because the emitter hits setpoint fast and holds it with tighter control. Over a full year, many plants see energy savings in the 15–20% range, and the replacement interval stretches—cutting maintenance labor and spare parts spend. A few shop-floor details that matter Installation is straightforward, but treat the lamp cleanly and align it to the reflector. Misalignment is how you get hot spots. Double-check the voltage matches your heater socket, and confirm the reflector condition—pitting or oxidation cuts output and will shorten lamp life. If you run high-clarity PET or heavy pigments, tell us; we can adjust the spectral output so you get uniform heating without scorching the preform surface.
