medium short wave infrared halogen lamp for blow moulding machine

Introduction

Let’s talk about a lamp that’s built for one job and one job only: keeping your blow molding machine humming. These aren’t your run-of-the-mill heaters. We designed these medium short wave infrared halogen lamps to put heat exactly where it matters—right where the polymer hits the mold. The whole point? Hit the perfect temperature lightning fast, keep those cycle times tight, and make sure the lamp keeps running, shift after shift, out there on the shop floor.

Technical Deep-Dive: Power, Voltage, and Dimensions

Here’s the thing about blow molding: you can’t wait around for heat to slowly creep up. You need it on demand. That’s where these shortwave infrared halogen lamps shine. They fire up and radiate intense energy within seconds. The standard setup is 400V at 2500W, and that’s no accident. Running high voltage at that power keeps the current manageable, which means smaller cables and less stress on your connections. The 300mm tube length and 12mm diameter are chosen to match the heating footprint on standard machines. You get a ton of heat density packed into a small space. Just keep this in mind: that kind of power puts heat into the chamber fast. So make sure your machine’s cooling and airflow are up to the task of keeping the ambient temperature in check.

Material & Design: Halogen, Quartz, and Connectors

Inside the quartz tube, the halogen cycle keeps the filament stable, even at scorching temperatures. This fights off blackening and keeps the output consistent over time. And the quartz itself? It handles the shock of rapid on-off cycling without cracking. Many of these lamps also use a reflective coating on the outside to direct infrared energy forward. That means more heat hits the target and less is wasted. On the electrical side, you’ll find the R7s bi-pin connector. It’s the standard for this tube size because it gives you a secure, low-resistance connection that’s easy to wire up and simple to replace without messing with the socket.

Application & Benefits: Built for the Blow Molding Line

On the line, this lamp heats the parison or preform with direct radiation. You get fast, localized control that feels immediate. The shortwave spectrum cuts through the surface efficiently, getting the material to the right temperature without turning surrounding components into hot messes. The compact 300mm size slips into tight spots, and the R7s connection makes replacement a simple drop-in job. Now, there is a trade-off. That high watt density means you need to pay attention to thermal management around the lamp and its mounting. But when it’s matched to the machine’s design, you get repeatable heat that keeps the line moving, without the guesswork.
