As business volume increases, some customers may need to cut thicker sheets, but existing machines can only meet the demand for cutting thin sheets. The machine may have only been in use for two to three years. Due to cost savings and limited customer budgets, we can help customers upgrade their machines. For example, a 1KW machine can be upgraded to 3KW, with only the need to replace the laser head, fiber optic device, chiller, and some wires. This saves more cost and time than purchasing a new device.
