Fixing the Heat Headache in KHS Blow Molding Lines

Ever pull a batch of PET bottles off the line only to find they look “pearly” or the walls are thin in some spots and thick in others? It’s frustrating. Usually, it comes down to one thing: your preforms aren’t heating evenly. When the heat is off, the stretch ratio fails. We see it all the time. OEM lamps start to degrade, the heat field shifts, and suddenly your quality control is a nightmare.

On the blow molding line, uneven preform heating is the fastest way to burn yield. You see it immediately—off-spec bottles, wall thickness that wanders, and scrap that shows up out of nowhere. The heating tunnel has to deliver repeatable energy, fast, cycle after cycle. We built our infrared heating approach to do exactly that on blow molders from Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB. What matters, technically We run short-wave infrared emitters with quartz elements—fast response, tight control. Power is matched to preform material and wall thickness, and the geometry follows the tunnel layout. Standard connections—R7s sockets and 24V control signaling—keep replacement straightforward. Temperature is closed-loop, with sensor feedback that keeps the heating profile stable even when line speed shifts. Power density is tuned so the preform surface heats quickly without scorching. Emitter life is rated to 5,000+ hours, with less than 5% output drop. Why it works on the floor In practice, the result is predictable. You get faster heating, shorter warm-up, and more consistent stretch behavior once the preform hits the mold. That means fewer rejects, less scrap, and a more stable OEE. Energy use comes down because the emitters deliver heat on demand, with minimal standby loss. And because the design aligns with OEM mounting and wiring, you can swap heaters without re-engineering the tunnel. The practical details Installation is straightforward, but alignment is critical. Mis-aimed emitters create hot and cold bands, and over-tightening can crack quartz. Verify the voltage and connector type for your machine, and make sure the emitter length matches the heating zone. Keep reflectors clean and inspect the insulation—performance depends on the whole thermal path being in order.
