550TPD Full Automatic Float Glass Production Line with Complete Tin Bath & Annealing Lehr System

This 550TPD full-automatic float glass production line is a large-scale, high-efficiency flat glass manufacturing system designed for industrial mass production. Utilizing mature tin-bath forming technology, molten glass spreads and levels on liquid tin to form ultra-flat, defect-free glass ribbon with exceptional optical performance.

The complete production line covers batching, melting, tin bath forming, annealing, and cold-end cutting. Equipped with a three-mode PLC intelligent control system, it ensures stable continuous operation, low defect rates, and simplified daily maintenance. Widely used for construction, automotive, mirror, and solar glass production applications.

• Excellent flatness & optical clarity: No waviness, distortion, or surface defects, achieving fire-polished high-transparent glass quality
• Precise thickness control: Stable tin bath temperature and traction speed ensure uniform thickness throughout the glass ribbon
• High durability: Finished glass features superior mechanical strength and chemical stability for extended service life
• Wide thickness range: Supports 2mm-19mm multi-specification production to meet diverse deep-processing requirements
• High automation level: Full-line PLC centralized control reduces manual operation and enhances production stability

Automatic weighing and mixing system with dust removal device to ensure accurate formula ratio.

High-grade refractory construction, energy-saving design, long service life, specially customized for 550TPD large output capacity.

Core forming equipment with stable temperature zoning and sealed structure to guarantee perfect glass flatness.

Supplies nitrogen-hydrogen mixed gas to prevent tin oxidation and avoid glass surface defects.

Optimized cooling curve design to release internal stress and improve glass stability.

Servo-driven cutting, inspection and stacking equipment for high-precision finished glass processing.

• 2-6mm: Building windows, automotive glass, mirrors, decorative glass
• 8-15mm: Shop front glass, interior partition, tabletop glass
• 19mm: Heavy-duty structural glass, large glass door

All glass can be further tempered, laminated and coated for deep processing applications.

Main raw materials include silica sand, limestone, dolomite, feldspar, soda ash, salt cake and cullet. Scientific formulation ensures high transparency, stable chemical performance and low bubble rate of finished float glass.
