Photovoltaic Equipment

01.

Photovoltaic monocrystal half-chip production line

It is the first cutting production line for half-chips, where, multiple processes have been adopted to achieve large-scale production of half-chips, including squaring, middle splitting, half-rod grinding, and half-chip cutting; it is the leading half-chips cutting technology in the industry.

Squarer Machine

02.

Double-station loop-wire squaring technology

It is the first double-brick vertical loop-wire squaring equipment, where, the non-destructive structure for wings collection is for the first time developed and applied, and the processing of half-brick as well as the rectangular brick can be compatible.

Grinding and Polishing Machine

03.

Composite grinding spindle technology

For the first time the coarse & fine grinding at same station is developed, which can reduce the fine grinding allowance, improve the machining accuracy and efficiency, and increase the service life of grinding wheel.

Slicing Machine
