We commenced production of multi crystalline ingots in May 2006. We have developed processing technologies to reduce our production costs at each step of the production process, which include recycling more poly silicon, producing bigger ingots, increasing wafer size, reducing wafer thickness, recovering slurry and increasing production yield.

We utilize large capacity, up to 800Kg charge size, state-of-the-art multi crystalline furnace equipment enabling LDK Solar to produce the highest industry quality standards in a cost effective manner. After rigorous inspection criteria, the multi crystalline ingots are squared by wire squaring machines. Through high-precision cutting techniques, the squared ingots are then sliced into wafers by wire saws using steel wires and slurry composed of silicon carbide and glycol. After the wafers are cut, they are cleaned and dried with a proprietary cleaning process and inspected to ensure adherence to strict customer bulk and surface quality requirements. Finally, the wafers are inspected before they are packed in boxes and shipped to customers or our cell facilities.
