The metal brake bending machine has high labor productivity and high work accuracy for bending metal sheets. It uses simple molds to press metal sheets into desired geometric shapes and can be widely used in electrical appliances, electronics, metal structures, instruments, meters, household hardware, building decoration, and other industries.

 

The metal press brake machines are divided into manual bending machines, hydraulic press bending machines, and CNC sheet metal brakes. Manual bending machines are divided into mechanical manual bending machines and electric manual bending machines. According to the synchronization mode, hydraulic bending machines can be divided into torsion axis synchronization, machine-hydraulic synchronization, and electro-hydraulic synchronization. According to the movement mode, hydraulic bending machines can be divided into the up-moving types and down-moving types.
