Infrared heating can support the interlayer-separation stage of laminated-glass cutting by applying controlled energy along a defined line or zone. It does not replace the scoring and breaking steps, and this arrangement should not be assumed suitable for every glass-cutting process. Cost claims are useful only when they compare equivalent glass, width, line speed, separation quality, reject rate and production conditions. Installed wattage or lamp price alone does not show the real process cost.
Record glass construction, thickness, cutting or scoring method, heated width, line speed, separation quality, electrical demand, rejects, downtime and maintenance. Use the same acceptance criteria for every comparison.
AGC's laminated-glass processing guide describes IR heating after scoring and breaking for its PVB products and cautions against overheating the edges.
Specify wavelength family, heated length, reflector direction, lamp-to-glass distance and the required heating-zone width. Confirm how curvature, coatings, interlayers and glass support affect energy delivery.
Measure actual electrical input over representative production and divide it by accepted output rather than comparing nameplate power. Use the same meter boundary and treatment of warm-up, standby and stops. This follows the U.S. DOE process-heating sourcebook's energy-per-unit-output approach.
| Input | Why it matters | Record |
|---|---|---|
| Process output | Creates a fair denominator | Accepted panels or metres |
| Energy | Shows actual operating demand | kWh during production |
| Quality losses | Captures hidden cost | Rejects and downtime |
Coordinate power with line speed and product detection. Define safe power reduction for stopped glass and verify the response after gaps, restarts and recipe changes.
Inspect separation consistency, edge quality, thermal marking and downstream handling. Include lamp life, cleaning, replacement labour, rejects and lost production when comparing the total process cost.
Compare the process with YFR's laminated-glass separation case and industrial infrared heating lamps. Confirm the final layout through representative glass trials.
No. Measure energy against equivalent accepted production.
No. Thickness, coatings and interlayers can change the response.
Gaps and restarts change heater and glass conditions.
Include energy, lamps, maintenance, rejects, labour and lost production.
Send YFR your material, dimensions, target, cycle time and current equipment details for an application-specific review.
