Introduction
We built this replacement lamp to fix one thing: giving every SIG Sidel blow molding machine a true drop-in heat source. Whether you’re running a classic SBO or the newest Matrix, this lamp fits the original footprint and electrical setup. No rewiring. No bracket fabrication. No downtime. Just swap the old lamp, wire in the new one, and get the line running again.
Power, Voltage, and Size: The Details That Matter
Preform heating needs the right kind of heat—precise, steady, and exactly where you want it. So we built this lamp around a fixed power profile and a 300mm quartz tube. That length matches the standard heating zone on Sidel machines, so the heat covers the preform from shoulder to neck without overheating the neck insert. Why 400V? High voltage means lower current for the same power. That keeps the wiring harness small and cuts resistive losses. In practice, that means less voltage drop at the terminals and temperature that stays consistent, run after run.
What It’s Made Of: Halogen, Coating, and a Connector That Stays Put
The tube is quartz, filled with halogen. The halogen chemistry helps keep the filament stable by redepositing evaporated tungsten—so the filament lasts longer and the tube doesn’t blacken. Quartz also handles rapid heating and cooling without cracking, which matters when machines are stopped and restarted often. A reflective coating on the outside pushes infrared energy downward onto the preform. Less heat wasted upward, and nearby parts stay protected. The connector is an R7s bi-pin. It locks in place and aligns the lamp inside the reflector socket. Misalignment causes hot spots and uneven heating, so that solid, repeatable fit matters more than you’d think.
Works Across Sidel Machines—Without the Hassle
This lamp is designed to work across the full Sidel lineup, from the SBO platform to the Matrix line. It matches the original mounting dimensions and the R7s interface, so you can swap lamps without modifying the reflector or bracket. In your plant, that means faster changeovers, fewer spare parts to stock, and heating performance that stays steady across different machine generations. One important note: because it runs at high wattage and high heat density, the machine’s cooling system needs to be in good shape. If airflow is blocked or the area around the machine runs too hot, the lamp will run hotter—and that shortens service life, no matter how well it’s designed. Keep the cooling path clean, and this lamp will run with the same thermal profile as the original, in the same footprint, without the headaches.
