Saw wire business that manufactures and sells electrodeposited diamond wires.

The saw wire business manufactures and sells electrodeposited diamond wires used for slicing electronic materials such as solar cells.

In order for solar cells to achieve grid parity, slicing with a fixed abrasive method (using electrodeposited diamond wire) is essential. We sought. We are contributing to the spread of solar cells by providing high-performance, low-cost electroplated diamond wire technology.

*What is grid parity?
It refers to the point (cost) where the cost of power generation by renewable energy is equal to or cheaper than the cost of existing power (power rate, power generation cost, etc.).
