The Manufacturing Process of Design Laminated Glass

The production of high-quality design laminated glass is a multi-stage process requiring precision engineering and adherence to strict quality control protocols. The primary objective is to create a durable, clear, and perfectly bonded composite structure.

Key Materials:

• Glass Substrates: Typically float glass, but can include tempered, heat-strengthened, low-iron, tinted, reflective, or patterned glass depending on specific project requirements. Common thicknesses range from 3mm to 19mm per pane.
• Interlayers:
  • PVB (Polyvinyl Butyral): Standard for safety, security, and acoustic dampening. Available in various colors and transparencies. Thicknesses typically 0.38mm, 0.76mm, 1.14mm, 1.52mm.
  • EVA (Ethylene-Vinyl Acetate): Offers excellent adhesion, humidity resistance, and transparency, often used for decorative or outdoor applications. Thicknesses from 0.38mm to 0.76mm.
  • SGP (SentryGlas Plus by DuPont): A stiff interlayer providing significantly higher strength, stiffness, and post-breakage performance compared to PVB, ideal for hurricane, blast, and structural glazing. Thicknesses from 0.89mm to 2.28mm.
  • Specialty Interlayers: Acoustic-specific films, switchable films (privacy glass), or interlayers with embedded materials (fabrics, meshes, LEDs).

Manufacturing Process Flow:

1. Glass Cutting: Raw glass sheets are cut to precise dimensions using CNC-controlled cutters, minimizing material waste and ensuring accuracy.
2. Edge Working & Grinding: Edges are ground and polished to remove sharp points, enhancing safety and reducing stress concentrations which can lead to cracks.
3. Washing & Drying: Glass panes undergo a thorough washing process with deionized water and are then completely dried to remove any dust, dirt, or contaminants that could compromise interlayer adhesion or optical clarity.
4. Interlayer Lay-up: In a clean room environment to prevent particulate contamination, the interlayer film(s) are carefully placed between the glass panes. For complex design laminated glass, multiple interlayers or decorative elements are precisely aligned.
5. Pre-pressing (Nipping/De-airing): The assembled glass-interlayer sandwich is passed through a nipper roll or a vacuum bagging system to remove trapped air and lightly bond the layers, creating a temporary seal. This stage ensures initial adhesion and prevents bubbles in the final product.
6. Autoclaving: The pre-pressed assembly is placed into an autoclave, where it undergoes a controlled cycle of heat and pressure. Temperatures typically range from 130°C to 150°C and pressures from 10 to 14 bar. This process completely fuses the glass and interlayer, creating a robust, bubble-free, and optically clear laminate.
7. Final Inspection: Each sheet of design laminated glass undergoes rigorous quality inspection for optical clarity, interlayer adhesion, edge quality, and overall dimensions to ensure compliance with specifications.
