EVA/TPT Online Cutting & Laying Machine for Solar Panel Production Line
The Ooitech GC-1500 EVA/TPT Online Cutting & Laying Machine is a high-performance automated cutting and laying system specifically engineered for solar panel manufacturing. This machine handles the precise cutting and placement of EVA, POE, PYE encapsulant films, and backsheet (TPT/KPK/KPE) materials onto glass substrates as part of an integrated solar module production line.
Designed to support cell sizes from 156.75mm to 210mm (G1, M6, M10, M12), the GC-1500 delivers a rapid 16-second production cycle with cutting accuracy of +/-2mm for EVA and +/-1mm for backsheet materials. The system features scissor-type upper and lower blade cutting, servo-controlled material feeding with constant tension, and automatic robotic stacking after each cut. An advanced isolation and reverse-flattening mechanism ensures wrinkle-free EVA laying every time.
The GC-1500 series is available in multiple configurations to match your production requirements, including single-layer EVA cutting (GC-1500FE), dual-layer EVA cutting (GC-1500SE), and dual-layer backsheet cutting (GC-1500ST). Each model integrates seamlessly into existing solar panel assembly lines and supports half-cut, full-size, single-glass, and double-glass module formats.
Whether you are building a new solar panel production line or upgrading your current EVA/backsheet cutting process, the GC-1500 provides the reliability, speed, and precision required for modern MBB, PERC, TOPCon, IBC, and shingled module manufacturing.
