**Mabilis na sagot:** Ang GC-1500 ay isang EVA at TPT online cutting at laying machine para sa mga linya ng produksyon ng solar panel. Gumagana ito sa mga format ng cell at module mula 156.75 mm hanggang 210 mm, pinuputol ang film sa kapal na tolerance na malapit sa 0.05 mm, na may mga sukat ng trabaho hanggang 1,500 mm at 1,500 W na drive. Pinupunit nito ang encapsulant at backsheet sheets sa tamang sukat at inilalagay ang mga ito sa stack online sa halip na mula sa pre-cut stock. Mahalaga ang inline cutting dahil ang EVA ay lumiliit at sumisipsip ng moisture kapag na-unwrap na, at ang sheet na pinutol sa fixed size isang araw bago ay maaaring hindi na magkasya sa module pagkatapos ng storage. Tinatanggal din ng inline cutting ang film trim waste na naiipon kapag ang mga sheet ay pinutol nang oversize at tinrim pagkatapos ng lamination.

## EVA/TPT Online Cutting & Laying Machine para sa Solar Panel Production Line

Ang **Ooitech GC-1500 EVA/TPT Online Cutting & Laying Machine** ay isang high-performance automated cutting at laying system na espesyal na dinisenyo para sa paggawa ng solar panel. Ang makinang ito ay humahawak ng tumpak na pagputol at paglalagay ng EVA, POE, PYE encapsulant films, at backsheet (TPT/KPK/KPE) materials papunta sa glass substrates bilang bahagi ng integrated solar module production line.

Dinisenyo upang suportahan ang mga sukat ng cell mula 156.75mm hanggang 210mm (G1, M6, M10, M12), ang GC-1500 ay naghahatid ng mabilis na 16-segundong production cycle na may cutting accuracy na +/-2mm para sa EVA at +/-1mm para sa backsheet materials. Ang sistema ay may scissor-type upper at lower blade cutting, servo-controlled material feeding na may constant tension, at automatic robotic stacking pagkatapos ng bawat cut. Ang advanced na isolation at reverse-flattening mechanism ay nagsisiguro ng walang gusot na EVA laying sa bawat pagkakataon.

Ang GC-1500 series ay available sa maraming configuration upang tumugma sa iyong mga pangangailangan sa produksyon, kabilang ang single-layer EVA cutting (GC-1500FE), dual-layer EVA cutting (GC-1500SE), at dual-layer backsheet cutting (GC-1500ST). Ang bawat modelo ay walang putol na nagsasama sa mga umiiral na solar panel assembly lines at sumusuporta sa half-cut, full-size, single-glass, at double-glass module formats.
