Getting Your Husky HyPET Heating Right

If you’re running a high-speed Husky HyPET system, you already know that just cranking up the wattage isn’t the answer. It’s not about how much heat you throw at the plastic; it’s about where that heat actually goes. The real struggle is getting the center of the PET preform hot enough to blow without torching the outside. That’s exactly why we build our lamps the way we do. We make sure the heat hits the core and reaches that sweet spot—the glass transition temperature—right before the blow cycle kicks in. Getting the heat to soak in Most standard IR lamps just bake the surface. You end up with a preform that looks scorched on the outside but is still cold in the middle. That’s how you get “pearlescence,” and nobody wants that. We fix this by tweaking the quartz and the halogen filling to shift the spectrum. By focusing on medium-wave IR, the heat basically ignores the “skin” and dives deep into the thick parts of the base and neck. It’s a much more natural soak. Speed, power, and a word of caution When you’re running high cycles, you need a rapid ramp-up. Our tubes are built for that intensity. Plus, they’re a direct drop-in for the Husky footprint. You won’t have to mess around with your reflectors or tweak your hardware. But here is the thing: high power density creates a lot of heat—not just for the plastic, but for the lamp itself. Your cooling blowers are doing the heavy lifting here. If your airflow is choked or dusty, the lamp temperature will spike, and you’ll be replacing tubes way sooner than you should. Keep those blowers clean. The nitty-gritty of installation We use heavy-duty connectors because arcing at the terminals is a nightmare in a 24/7 shop. These lamps are built to take a beating, but they still rely on a good connection. A loose socket is a silent killer. It creates a hot spot that burns out the tube prematurely. When you’re wiring these in, double-check that the tension is tight. If the voltage drops across the line, your oven bank won’t pull an even load, and you’ll be chasing heating inconsistencies all shift.
