On a Husky HyPET line, preform heating is where the money gets made—or lost. When the original lamp starts to fade, you end up chasing inconsistent stretch, short shots, and scrap. And you’re paying overtime just to swap lamps too often. We built the Husky HyPET preform heater lamp to cut that cycle off at the knees.
What matters under the hood
This is a short-wave infrared halogen emitter, designed to match the HyPET heating tunnel geometry. Quartz envelope, tungsten filament—tuned for fast, repeatable heat-up and tight temperature control. It’s engineered to the OEM footprint, right down to the R7s connector and overall length, so it drops straight into the existing lamp holder without touching the reflector or wiring harness. Wattage and voltage match the HyPET spec, so the control system sees the same load it expects. The spectral output is chosen to get through the preform wall efficiently, so stretch blow molding gets consistent biaxial stretching.
Why it fits the HyPET reality
On a Husky HyPET, the heat-up has to keep up with high-cavity indexing, and the stability has to hold across long runs. This lamp hits target temperature fast, then sits steady—less swing, which means fewer uneven walls and less flash. The payoff is fewer rejects, fewer manual tweaks, and more uptime. Because output stays stable over time, lamp life stretches out and unplanned changeouts drop. Energy use stays where it should, since the wattage matches the original—no overdriving, no underperforming.
The practical details
Installation is plug-and-play only if lamp length, base type, and wattage line up with your exact HyPET model and holder. Check voltage and connector before you order, and make sure the reflector is clean and aligned—dirt on the reflector will steal output no matter what lamp you run. Handle the quartz with gloves to avoid contamination, and run a short warm-up ramp to protect the filament. You’ll get the best life when heating zone setpoints stay stable and the preform dryer keeps material consistent and dry.
