Customizing shaped glass is complex; here are five key details you need to understand.
1. Material and Process Compatibility
Glass Thickness and Strength: The thickness of shaped glass (e.g., 3mm-19mm) must be selected based on size, shape, and application to avoid breakage due to thinness or increased cost due to excessive thickness.
Matching Processing Technology: Complex shapes require hot bending, cold bending, or CNC machining. For example, curved glass requires precise temperature control in a hot bending furnace, while right-angled shapes require CNC grinding.
2. Size and Space Constraints
Production Equipment Limits: The width of glass sheets is typically 2-3 meters, and the length is 6-12 meters. Oversized pieces require custom extra-large furnaces or splicing processes, drastically increasing costs.
Transportation and Installation Constraints: Transportation vehicles are typically limited to a width of 2.5-3 meters. Old building doorways and elevator sizes may hinder transportation, requiring advance planning for disassembly.
3. Relationship Between Shape and Cost
Complexity and Defect Rate: The defect rate for shaped glass cutting can reach 30%. Curved and multi-curved glass requires special molds, resulting in costs 50%-200% higher than flat glass.
Premium for Special Processes: Coating, lamination, and tempering increase costs. For example, tempered glass is limited to a maximum size of approximately 2.44 meters in width and 5 meters in length.
4. Safety and Regulatory Compliance
Structural Safety: Shaped glass must pass wind pressure and earthquake resistance tests. For example, the "Technical Regulations for Building Glass Applications" specify the maximum allowable area for glass of different thicknesses.
Fire and Lightning Protection Requirements: Must comply with "Building Design Fire Prevention Code", such as limiting the opening area to within 1.8 square meters to avoid escape obstacles in case of fire.
5. Supplier Qualifications and Case Studies
Technical Capabilities: Choose a manufacturer with experience in processing shaped glass, such as mastering the full process technology of hot bending, CNC machining, and tempering.
Project Case Studies: Refer to past cases for complexity and completion, such as the precision of curved glass splicing and the stability of shaped structures.
Summary of Pitfalls: Customizing shaped glass requires balancing design effect with cost and safety. Confirm the supplier's technical capabilities in advance to avoid cost overruns or delivery delays due to size limitations or complex shapes.
