The 3000W Short Wave Halogen Heating Lamp for Blowing Machines
We built this 3000W short wave halogen heating lamp for one reason: the blowing machine floor. It’s all about getting intense heat exactly where you need it—right onto the parison or preform—without wasting energy. This isn’t some general-purpose heater. It’s a focused tool, built to match the exact thermal needs of PET and other blow molding work.
Power, Voltage, and Size: What It Brings to the Table
We went with 3000W because that’s what it takes to soften material fast. That kind of power gets the surface up to temperature quickly, so your cycle times stay tight. It runs at high voltage, usually 400V. That means you get the same power with lower current. And lower current? Smaller wiring, less voltage drop, and less heat building up inside the machine. The lamp is compact—about 300mm long—so it fits into those tight heating zones where space is at a premium. But packing this much power into a small body means it runs hot. So make sure your machine’s cooling and ventilation are up to the job.
Why Short Wave Halogen Works (and How It’s Built)
Inside, you’ve got a short wave infrared halogen element, sealed in a quartz tube. Quartz can handle the brutal thermal shock of rapid on/off cycling, and it transmits infrared energy cleanly. The short wave output hits the material directly, heating the parison from the outside in. It’s faster and way more controllable than trying to heat the air around it. A reflective coating on the back of the tube pushes all that energy forward, so more of it lands on the product instead of radiating backward. And the connections? It uses an R7s or SK15 connector. These are tough, two-pin ceramic terminals made to carry high current without melting. They give you a secure, low-resistance connection that can take the daily thermal cycling of a production floor.
What It Feels Like on the Floor
On a blowing machine, you need heat that’s predictable and repeatable. This lamp gives you exactly that—focused energy right where it matters. The payoff is a consistent parison temperature, which means uniform wall thickness and fewer rejects. Installation is straightforward. The compact size and standard connector mean it drops right in. The halogen cycle helps keep the element clean and stable, so it lasts longer than standard IR bulbs. Just keep this in mind: it’s intense. Treat it with care, make sure it’s properly shielded, and keep adequate clearances. For engineers running blowing machines, this lamp is a practical, reliable way to solve a tough heating problem.
