Getting Your PET Preforms Heated Right

If you’re running a high-speed bottle blowing line, you know the struggle. You need the plastic hot enough to shape, but not so hot that you’re scorching the surface. That’s where our carbon fiber lamps come in. Most people are used to standard quartz heaters, but these are different. We use a carbon fiber filament that puts out short-wave infrared radiation. In plain English? The heat sinks deep into the PET wall almost instantly. It’s fast. Really fast. And it means you aren’t just baking the outside of the preform while the inside stays cold. Let’s talk power. We’ve tuned the wattage and voltage to keep up with the breakneck speed of industrial machines. You can hit that glass transition temperature in a matter of seconds. Just a heads-up: make sure your power supply can handle that first big surge when you flip the switch. Also, don’t just crank up the wattage and call it a day. If you don’t have the right airflow, you’ll end up with burnt plastic. Nobody wants that. Built for the shop floor We wrap the filament in high-purity quartz. It’s basically a clear window that lets the infrared heat slide right through without getting stuck. And because we know you don’t have time for a headache during a shift change, we use standard industrial connectors. You can just pop the old, worn-out tubes out and slide these in. No fuss. We also toughened up the joints, so the vibration of a high-speed run won’t shake them to pieces. Making it work in the oven Here’s the best part: these lamps stop those annoying “cold spots” in your oven. Instead of wasting energy heating up all the air around the plastic, the heat goes straight into the preform. Your energy bill will thank you. But, you’ve got to keep them clean. Seriously. A little bit of dust or grime on the glass creates hot spots, and that’s how tubes crack. Keep them sparkling and make sure there’s a bit of breathing room between the lamp and the plastic so nothing warps. Simple as that.

Introduction

In the PET bottle blowing process, the heating stage dictates the entire line’s speed and quality. We built the medium-wave carbon fiber heat lamp specifically for this job. It replaces older halogen and short-wave designs with a focused, fast-response heat source that gives you tighter control over parison temperature without overloading the machine’s electrical budget.

Technical Deep-Dive: Power, Voltage, and Dimensions

Medium-wave carbon fiber lamps are designed to deliver high heat density in a compact footprint, and the numbers tell the story. We spec these lamps to run at 400V, which allows the same power output with lower current compared to a 230V unit. Lower current means thinner wiring, smaller contactors, and less heat buildup in the control cabinet. Wattage is typically 2500W in a 300mm length. This combination concentrates energy into the parison zone, giving you rapid heating and fast recovery after bottle indexing. The 300mm length matches standard blowing head spacing, so you can drop the lamp into existing mounts without redesigning the clamp or oven section. The trade-off is straightforward: high power density demands proper cooling. If your machine runs at high duty cycles, the reflector area and lamp mount must be designed to shed heat, or you risk thermal stress on nearby components.
