HJT Module Frame Structural Grouting Solution
Coordinate four-edge solar module frame positioning, two-component adhesive dispensing, corner assembly and a separately verified green-cure handling stage.
Buffer-Free Fast Structural Framing for Large-Format Dual-Glass Modules
Coordinate four-edge solar module frame positioning, two-component adhesive dispensing, corner assembly and a separately verified green-cure handling stage. The described scope includes frame positioning and pressing, proportioning, multi-head dispensing and conveyor interfaces. Adhesive, extrusions, glass, handling fixtures and cure residence are confirmed for the module. This assembles existing frames; it is distinct from manufacturing composite profiles.

Capacity and acceptance
Review all preparation, dispensing, curing, handling and inspection stages. Material and component results require separate original test records.
Configuration references are reviewed for the selected material, product geometry and acceptance conditions. A 25-second framing cycle precedes the stated 180-second green-cure handling threshold; protected parallel residence or fixtures are needed rather than immediate unrestricted palletizing. At least eight 25-second positions are required to cover 180 seconds before downtime allowances. Weight and volume 1:1 ratios cannot be equated without density data. ASTM D1002 covers metal-to-metal specimens and does not directly establish glass-to-aluminum joint performance. The stated 100,000 modules in 15 days of two 8-hour shifts also needs reconciliation: two cells at 23.8 seconds each can produce at most about 72,605 modules in that period before downtime.

Dual-Glass Infeed & Automatic Centering
Configured reference: Laminated G12 dual-glass panels transfer via motor rollers into the machine bed, centered within ±0.5 mm by pneumatic aligning pushers.
4-Corner Synchronous Hydraulic Pressing
Configured reference: Four servo-hydraulic cylinders drive corner keys into frame extrusions under 50 kN force, squaring the frame around glass edges.
Closed-Loop Two-Component High-Pressure Metering
Configured reference: Servo gear pumps displace structural polyol and modified isocyanate at 9.0 MPa under Coriolis mass flow measurement within ±0.2% accuracy.
