On the blow molding floor, thick preforms don’t just need heat—they need the right heat, right when it counts. If the heating tunnel can’t hold a stable thermal profile, you’re dealing with uneven stretch, crystallized necks, and scrap that climbs fast. We built a high-intensity IR lamp specifically for thick preforms to fix that, matching energy delivery to the wall thickness and the geometry you’re running. The heart of it is a short-wave quartz halogen emitter, built for power density and repeatable output. We spec the filament and reflector geometry to shape the heat flux, so the preform surface takes energy quickly while the interior catches up—without scorching the outside. The lamp runs on a tuned voltage and current curve, letting you match power precisely to each heating zone on the blow molder. The payoff is a controlled temperature rise and a predictable thermal field across the preform wall. This matters because thick preforms need deeper, more uniform heat penetration to stretch cleanly. With this lamp, you can push higher output without driving the preform into thermal shock. You’ll see shorter heating times, more consistent bottle weight, and fewer pinholes and stress marks. Energy use drops too, because the emitter switches fast and puts the heat where it belongs—on the preform, not the machine frame. Installation is straightforward on Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB machines, using standard R7s connectors and mounting dimensions. Just plan for clean power and get the reflector alignment right—if the lamp is off-target, you lose peak efficiency and risk hot spots. Also keep the preform surface free of oils and residues; even a thin film changes absorption and shifts the heating curve. Match the lamp wattage to the OEM’s zone rating, and the heating profile will settle in fast.
