Laminated Glass Cutting with Infrared Heating Lamp 500V 5900W 3870MM

Due to the high toughness of the PVB interlayer, conventional mechanical cutting of laminated glass often results in edge chipping or residual interlayer material, which has long been a technical challenge in the industry. High-end cutting machines from leading brands address this issue by integrating infrared heating tubes. Through directional radiant heating, these systems enable simultaneous softening of the PVB interlayer and glass cutting, effectively overcoming the technical bottleneck and establishing themselves as a core component in laminated glass deep-processing equipment.

Working Principle: After the glass is scored and separated, the infrared heating tube rapidly radiates heat onto the cutting gap. Fast medium-wave infrared rays (wavelength range 1.4–2.0 μm) closely match the peak absorption spectrum of the PVB interlayer, achieving an absorption rate of over 90% in the interlayer, while the glass itself absorbs minimal energy. This enables precise heating of the interlayer without heating the glass. Once the interlayer is rapidly softened, the glass layers can be easily separated.

Key Advantages: Compared with traditional resistance wire heating, infrared heating tubes offer three significant advantages:

Directional radiation efficiency increases by 30%, reducing PVB interlayer softening time to within 15 seconds. Such as Bottero glass cutting machine and etc..

Temperature control accuracy reaches ±2°C, improving glass edge flexural strength by 25%. Such as LISEC glass cutting machine and etc..

Non-contact heating eliminates surface scratching, increasing the cutting yield rate from 82% to 98%. Such as INTERMAC glass cutting machine and etc..
