Let’s talk about the 650mm Ruby Quartz IR Lamp
If you’re running PET blowing machines, you know the struggle of getting that preform heated just right. That’s why we built these 650mm lamps. At 230V and 800W, they’re designed to spread heat evenly across a long stretch. No weird cold spots. No uneven plastic. Just a consistent heat that gets the job done before the stretch blow happens. The nitty-gritty on power Since these are 800W over a 650mm length, you don’t have to worry about localized hot spots burning your material. We stuck with the 230V standard because it just works with most industrial grids. You can wire it straight into your control system without messing around with clunky step-down transformers. One quick tip: these tubes are long. If they aren’t seated perfectly in your oven rack, they can bow. Keep an eye on that during install. Why the “Ruby” part matters We use ruby-coated quartz for a reason. The coating acts like a filter, pushing the energy directly into the plastic instead of wasting it by heating up the air or the machine frame. And the halogen cycle? That’s the secret sauce. It keeps the tungsten filament from thinning out too quickly. Since these lamps are constantly clicking on and off, that extra durability means you aren’t replacing them every other week. Keeping things moving on the floor In a blowing machine, speed is everything. You can’t wait around for a lamp to warm up. These hit their operating temperature almost instantly, so your cycle speeds stay high. But here’s the catch: that ruby coating puts a lot of thermal stress on the glass. If your cooling fans quit or something blocks the airflow, the quartz can crack from the shock. Just make sure your ventilation can handle 800W per lamp. It’ll save you from a premature burnout and a lot of headaches.
