Oil bottle thick preform heater module

On the line, oil bottle preforms are heavier and thicker than standard PET, so the heating tunnel has to dump heat in fast—and do it evenly. Let the profile drift and you’ll see weak necks, crystallized shoulders, or parisons that blow out. That burns resin, drags down the blow molder, and keeps you re-tuning all shift.

What matters under the hood

We built the oil bottle thick-preform heater around short-wave infrared halogen emitters in quartz tubes. They respond quickly and pack serious power density. You can spec 1.5–3.0 kW per zone, 220–480 V to match your plant, and fit the physical envelope of your heating tunnel, right down to standard R7s connectors. The reflector geometry is shaped to concentrate the beam pattern on the preform wall, and closed-loop control keeps the thermal profile tight across the neck and body. With thick sections, the module drives heat in faster without scorching the surface—so cycle time comes down and stretch ratios stay stable.

On the floor, a blow molder running flat-out can’t live with uneven preform heating. When the heating tunnel is off, you see it in the bottles—weak necks, crystallized bases, wall thickness that drifts. The line slows down, scrap piles up, and you spend time chasing temperature instead of making parts. What matters, technically We build our water-bottle preform preheat modules around short-wave quartz emitters, tuned to the preform wall and how the material absorbs energy. Power density is controlled, not guessed at. The heating profile is engineered as a clean temperature rise curve, so the surface heats fast while the core hits target without scorching. We shape the thermal field across the heating tunnel to keep it even—no hot spots, no cold seams. Power is matched to the blow molder’s electrical spec and the preform cycle, so emitter output lines up with dwell time instead of fighting it. This is penetration heating done right: energy goes where it needs to, period. Why it plays on these machines Drop it into a Sidel, Krones, SIPA, Husky, SACMI, or Nissei ASB blow molder and it fits the existing heating tunnel geometry. Warm-up is quicker, setpoints are repeatable, and heating stays stable even at high cavitation. You get fewer rejects, bottle weight that holds steady, and less downtime chasing temperature swings. Energy use drops because the emitters hit target fast and hold it with tight control, instead of over-running the heaters. Here are the details that bite you if you ignore them Matching the lamp length, base type, and connector—often R7s—to your blow molder model matters. During install, check clearance around the preform path and make sure the reflectors are aligned. And if the line runs multiple preform sizes, the heating curve and power settings will need retuning. Plan a short validation run when you switch formats.
