The brake system with a metal core is the core technology of the new generation of roller blinds, roman blinds and other interior window treatment roller blinds systems.

The system uses a special metal shaft with high precision. The brake performance is realized by the German imported piano wire spring with high precision, which greatly reduces the friction damping of the system, and the planetary gear reduction mechanism with high precision and special reduction ratio is used to realize the labor-saving effect of the system.
