Hanuuha TechM Multi Wire Sawing System Main Roller Management Wire Management Slurry Management An Advanced Cutting Machine for Solar Wafers An equipment that cuts polysilicon bricks into wafers (120~180f<m) which are the base of solar cells The multi wire saw is used for the watering process where polysilicon bricks are used to produce wafers with a thickness of 120~180um to be used as the base of solar cells. The PSM10 model processes 1,000mm bricks placed in series. Diamond wires can be applied to the multi wire saw. Maximum yield and highest wafer quality Convenient optimal structure User-friendly operating system

The existing open slurry tank was modified to an underground type and made to be more compact, reducing 10-15% of the existing installation space. Also, the durability and performance of the main roller have been improved for more pow- erful cutting, ultimately contributing to increase in productivity.
