Introduction

We built this 650mm, 1500W halogen infrared heat lamp for one reason: PET bottle blowing. This isn’t a general-purpose heater you throw at a bunch of different jobs. It’s built to put intense, focused heat right where it matters—on the preform. The point is simple: get the material up to the glass transition temperature fast, evenly, so it stretches the way you want. No scorching. No thin spots. Just predictable results.

Power, Voltage, and Geometry—Why It Works

The 1500W rating at standard line voltage gives you heat output you can count on, so you can match it to your cycle times and the wall thickness of your preforms. And the 650mm length? That’s chosen to cover the whole preform in many blow-molding setups, creating a heating zone that stays consistent—no hot spots at the ends, no cold shoulders. The length-to-power balance is the sweet spot: enough energy density to heat quickly, but balanced so the center doesn’t get overdriven while the ends lag behind.
