Halogen Heating Lamps for Blow Molding: Power, Precision, and Reliability

Let’s get straight to it. A halogen heating lamp for a blow molding machine isn’t just some fancy light bulb. It’s a compact, high-intensity workhorse, built to melt parisons fast and do it the same way, every single time. We designed these lamps to pack the heat needed for materials like PET and HDPE, hitting that perfect melt point without ever overshooting it.

Power, Voltage, and Size: The Sweet Spot

We build these around a 400V electrical setup, typically paired with 2500W of output. That power gets pushed through a tight, compact quartz envelope. The payoff? You get rapid ramp-up and rock-solid, stable temperatures between 500–700°C. The 300mm tube length gives you a precise heating zone that lines up perfectly with standard parison lengths. This means you’re putting the heat exactly where you need it, and not wasting a single watt of energy anywhere else.

Built to Last: The Materials and Design

At the heart of it is a high-purity quartz tube. We chose it for its ability to handle thermal shock and its extreme temperature limits. Inside, a shortwave halogen element delivers intense infrared heat that responds instantly. A reflective coating focuses all that energy forward, so more of it gets absorbed by the parison and less is wasted. And the R7s connector? It provides a secure, two-point contact that handles the current without getting hot at the terminals. It’s a straight-forward, drop-in replacement you can trust.

On the Line: Why It Works

Out on the blow molding line, these lamps deliver the concentrated heat needed to keep cycle times short, with consistent melt control. They’re compact enough to fit into tight machine bays, and the tough quartz envelope handles the constant heating and cooling of continuous production without blinking. Now, here’s the one thing to keep in mind: that focused 2500W output means you need a properly sized cooling and ventilation setup. It’s essential to keep the lamp and the surrounding parts at a safe, stable temperature.
