On the blow molding floor, a SIPA stretch blow molder that can’t hold a steady preform temperature is a profit leak. Underheated preforms stretch weak, and the blown bottles come up short on pressure. Overheating scorches the material. Every minute you spend chasing the heating tunnel is a minute lost to scrap and restarts. What matters under the hood We built this infrared lamp for SIPA machines at 400V, 2500W, so it lines up with the heater circuits and power budget of the original design. The short-wave emitter responds fast and holds tight control across the heating zones. Preform heating is time-critical: the material has to hit the right temperature profile in seconds, then stay there. The quartz tube runs hot and stable, and the R7s connector drops straight into the standard mount. Swap is clean, repeatable. Why it plays nice with a SIPA blow molder On a SIPA, consistent preform heating translates to consistent stretch, consistent weight, and fewer rejects. With this lamp, you get repeatable output from startup through long runs, so the heating tunnel isn’t fighting the rest of the machine. Energy stays in line because the emitter comes up fast and holds setpoint without hunting. Longer service life means fewer shutdowns for lamp changes, which helps keep OEE steady. The shop-floor details Installation is straightforward, but the heating window is sensitive. Make sure the lamp is aligned to the reflector and secured without stress on the R7s ends. Verify your thermocouple and controller are reading true. Expect slightly higher inrush current on cold starts, so confirm the wiring and terminals are tight and rated for the load. Match the lamp to the machine, and the process follows.
