Introduction
We built this 220V quartz halogen lamp to be the heat source for blow machines that need one thing: fast, steady heat—without turning the thermal system into a science project. It’s small, radiant, and designed to keep temperature control predictable on the blow molding line.
The Real-World Details: Voltage, Length, and Power
Running on 220V keeps the wiring straightforward and eases the load on the electrical side. Compared with low-voltage options, that means less heat at the contacts and a simpler supply path. We set the length at 350mm because that’s what fits the heating zone on most blow machine neck heaters. It gives you even coverage across the parison—no hot spots, no guesswork. Wattage is chosen to pack enough heat density for PET and similar polymers. But here’s the trade you already know: this lamp runs hot. So you’ve got to plan your airflow and insulation to keep both the machine components and the people around it safe.
What It’s Made Of: Quartz, Halogen, and a No-Fuss Connector
The envelope is quartz, and that matters when temperatures swing fast. It handles thermal shock way better than glass—especially on cold starts and when production pauses. Inside, the halogen cycle helps keep the filament stable by putting evaporated material back where it belongs. The payoff is steady output over time, with less blackening. And the base? It’s an R7s, a standard double-ended connector. It holds tight, and it makes replacement simple. No custom brackets. No wrestling. Line it up and push it in.
Why It Works on the Floor: Fast Heat, Fast Swap
On a blow machine, you need heat that comes on quickly, holds the setpoint, and installs without drama. This lamp delivers that in a compact package with radiant heat you can count on. It drops right in where standard neck heaters go, so changeover is faster and the machine keeps moving. Yes, the high heat density means you need proper cooling and clearance. But when you spec it right, you get stable heating—and fewer surprises that shut the line down.
