NCM-ZW torsion bar press brake is extensively used for forming various types of steel and stainless steel door frames, or for the forming of the lock side/hinge side of the front and back panels of the door leaf. This sheet metal bending machine is equipped with a torsion bar synchronous adjustment structure, which can achieve precise bending operations at multiple angles and degrees by precisely controlling the movement of the torsion bar. Its main motor power ranges from 5.5kW to 18.5kW, and the nominal pressure can reach 630KN to 2000KN. Through the electrical control system, operators can easily set bending angles, bending lengths, and other parameters.
