Glass score line heating lamp

On the line, a score line that doesn’t split cleanly is money going out the door—either a lite shattering from thermal shock, or a ragged edge that gets flagged downstream. Usually, the culprit is uneven heat right where you scored: hot spots and cold spots throw the thermal stress out of balance, and the glass pushes back. What matters under the hood We built the score-line heating lamp around short-wave infrared elements in a quartz envelope. They respond fast and pack serious power density without dumping extra heat into the air through convection. The reflector geometry and element spacing are tuned to give you a uniform thermal field across the score line, not just a high peak. You dial in the power precisely, and the heat profile holds steady along the full length of the lamp. In practice, that translates to repeatable heating for straight and curved cuts, with far less temperature drop-off at the edges. It drops straight into existing cutting and breaking stations—standard mounting and terminals that line up with typical industrial controls. Why it holds up on the floor When the score line gets even energy, localized expansion stays controlled, which cuts the risk of fracture and optical distortion. You get a clean, predictable separation—fewer micro-cracks, fewer rejected lites, and less downtime spent clearing jams. The fast ramp-up keeps pace with high-throughput tempering, bending, and lamination lines without forcing you to add dwell time. Energy goes where it needs to—into the glass—not into heating the frame or the air, so your operating cost per square meter stays predictable. Installation is straightforward, but alignment is everything. The lamp has to track the score wheel path, and the distance to the glass needs to be fixed and repeatable; even a small offset shifts the thermal profile and shows up as edge variability. Ambient airflow and reflective surfaces can nudge temperature stability, so shield the zone and verify setpoints against glass type and thickness. Expect shorter lamp life if you run at maximum power continuously—plan periodic output checks and keep spare elements on hand.
