When your heating tunnel starts drifting, your first move should be the lamp. Uneven preform heating shows up quick—thin walls, crystallization, and a growing stack of rejects. We built the Clear Quartz Lamp R7s 1000W 230V to drop straight into the same lamp positions on mainstream blow molders. No rewiring. No retuning. What matters under the hood It’s a short-wave infrared halogen emitter, housed in a clear quartz tube, sized for R7s sockets. Rated 1000W at 230V, it sits inside the same power and voltage envelope used in Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB heating sections. The quartz envelope transmits high-intensity IR, so preforms heat fast and directly. The R7s base gives you the same mechanical fit as the OEM lamps. In practice, you can replace lamps one-for-one and keep the same heat profile across the tunnel. Here’s the thing about a blow molding line: time and repeatability are the only currencies that matter. This lamp comes up to operating temperature quickly, so you spend less time waiting for the heating zone to stabilize after a swap. That means more consistent preform skin temperature, fewer temperature-related rejects, and cycle rates that stay stable. Energy use stays close to the original spec because the wattage and voltage are aligned with the machine’s design. What to watch on the floor The quartz envelope runs hot, so handle it with clean gloves and keep the reflectors aligned. Misalignment is the fastest route to lost output and hot spots. Also, check the socket condition—worn contacts create voltage drop and uneven heating. If your line runs long hours, swap lamps by hours instead of waiting for failure. That simple move keeps unplanned downtime off the schedule.
