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 chosen based on size, shape, and application to avoid breakage due to thinness or increased costs due to excessive thickness.
Matching Processing Methods: 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 the original glass sheet 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 have width limits of 2.5-3 meters. Old building doorframes and elevator sizes may hinder transportation, requiring advance planning for disassembly.
3. Shape and Cost Relationship
Complexity and Defect Rate: The defect rate for shaped glass cutting can reach 30%. Curved and multi-curved glass requires special molds, increasing costs by 50%-200% compared to flat glass.
Special Process Surcharges: Coatings, lamination, and tempering increase costs. For example, the maximum size for tempered glass is limited to 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" specifies the maximum allowable area for glass of different thicknesses.
Fire and Lightning Protection Requirements: Must comply with "Building Design Fire Protection 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 entire process of hot bending, CNC machining, and tempering.
Project Case Studies: Refer to the complexity and completion of past cases, such as the precision of curved glass splicing and the stability of shaped structures.
Summary of Pitfalls: Customizing shaped glass requires balancing design effects with costs and safety. Confirm the supplier's technical capabilities in advance to avoid cost overruns or delays due to oversized dimensions or complex shapes.
